"Atkinson Vos are the absolute experts on UNIMOGS in my opinion. They offer wonderful advice apart from sourcing spares and thereby make things so much easier"

"Simon and Frank are passionate in what they do and men of their word. That"s what I think sets them apart. They have literally turned me into a Unimog addict."

"Mark has done a fantastic job and in poor weather conditions too, he resolved an unexpected pump failure and replaced it in time for us to use the Unimog almost immediately after he finished. Our unimog has been on some high profile jobs since Mark left and has impressed all who have seen it in action"

"As a company owner Great British sports cars in the automotive sector, I know how important it is to have a team that offers great customer service but also has the depth of technical knowledge of their products, this has been especially helpful with a personal project of mine restoring an 1969 Unimog 416 were finding people that really know there stuff has been invaluable."

The load-sensing system is a hydraulic control mechanism in which the pressure and/or flow volume of the hydraulic pump is/are adapted to the conditions required by the consumers. In regular hydraulic circuits, the flow volume to the motor is throttled by means of pressure restriction valves or pressure control valves. The hydraulic pump always supplies the full power, even in the case of the flow volume being throttled. In some cases, this can cause high power losses. The load-sensing system, however, ensures that the pump only supplies the flow volume which is currently required for all active consumers.

A hydraulic valve is a mechanical device that regulates the flow of the hydraulic fluid in a hydraulic system. Hydraulic systems are typically high pressure systems, ranging from 200 Bar averaging 700 Bar upwards...

There are three variants of transmission-driven power take-off available. For example, the rapid transmission power take-off with 4-hole flange can be used to drive hydraulic pumps. The rotational speed and direction of the power take-off are the same as the engine speed and its direction of rotation. For implement control from outside the cab, a remote control is also available. Programming of the maximum rotational speed prevents overstepping the permissible upper rotational speed limit.

Equally as powerful is the transmission-driven power take-off with 6-hole flange. For applications whereby a very high power take-up is required, such as for fire service pumps, the third variety – also with standardised 6-hole flange – offers an optimal solution. With a nominal engine speed of 2200 rpm, a working speed of up to 3606 rpm can be attained. Here, too, a remote control for use outside the vehicle is also available.

The Unimog (Daimler Truck (formerly Daimler-Benz, DaimlerChrysler and Daimler AG) since 1951. In the United States and Canada, the Unimog was sold as the Freightliner Unimog.

Unimog production started in 1948 at Boehringer[de] in Göppingen. Daimler-Benz took over manufacture of the Unimog in 1951, and first produced it in their Gaggenau plant. From 1951, the Unimog was sold under the Mercedes-Benz brand. However, the first Unimog to feature the three-pointed Mercedes-Benz star was only introduced in 1953. Since 2002, the Unimog has been built in the Mercedes-Benz truck plant in Wörth am Rhein in Germany.Mercedes-Benz Türk A.Ş. plant assembles Unimogs in Aksaray, Turkey.González Catán factory near the city of Buenos Aires.: 141: 122

The first model was designed by Albert Friedrich and Heinrich Rößler shortly after World War II to be used in agriculture as a self-propelled machine providing a power take-off to operate saws in forests or harvesting machines on fields. It was designed with rear-wheel drive and switchable front-wheel drive, with equal-size wheels, in order to be driven on roads at higher speeds than standard farm tractors. With their very high ground clearance and a flexible frame that is essentially a part of the suspension, Unimogs are not designed to carry as much load as regular trucks.: 7

Due to their off-road capabilities, Unimogs can be found in jungles, mountains and deserts as military vehicles, fire fighters, expedition campers, and even in competitions like truck trials and Dakar Rally rally raids. In Western Europe, they are commonly used as snowploughs, municipal equipment carriers, agricultural implements, forest ranger vehicles, construction equipment or road–rail vehicles and as army personnel or equipment carriers (in its armoured military version). New Unimogs can be purchased in one of two series: medium series 405, also known as the UGN ("Geräteträger" or equipment carrier),: 4 and heavy series 437, also known as the UHN ("Hochgeländegängig" or highly mobile cross country).

The name Unimog is pronounced German "UNIversal-MOtor-Gerät", Gerät being the German word for a piece of equipment (also in the sense of device, machine, instrument, gear, apparatus). It was created by German engineer Hans Zabel, who made the note Universal-Motor-Gerät on one of the technical drawings for the Unimog. Later, the Universal-Motor-Gerät was shortened to the acronym Unimog. On 20 November 1946, the name Unimog was officially unveiled.: 8 Since 1952, Unimog has been a brand of Daimler Truck.

The Unimog"s characteristic design element is its chassis : a flexible ladder frame with short overhangs, and coil sprung beam portal axles with a central torque tube and transverse links. Having portal axles, the wheels" centres are below the axle centre, which gives the Unimog a high ground clearance without the need for big tyres. The coil sprung axles with torque tubes allow an axle angle offset of up to 30°, giving the wheels a wide range of vertical movement to allow the truck to drive over extremely uneven terrain, even boulders of one metre in height.: 23

Unimogs are equipped with high visibility driving cabs to enable the operator to see the terrain and more easily manipulate mounted tools. The newest implement carrier Unimog models can be changed from left-hand drive to right-hand drive in the field to permit operators to work on the more convenient side of the truck. The ability to operate on highways enables the Unimog to be returned to a home garage or yard to thwart vandalism.

Unimogs can be equipped with front and rear tool mounting brackets and hydraulic connections to allow bucket loaders and hydraulic arms to be used. Most units have a power takeoff (PTO) connection to operate rotary equipment such as snow brooms, snow blowers, brush mowers, loaders or stationary conveyor belts.

Unimogs are available with short wheelbases for implement carrier operations or long wheelbases for all-terrain cargo carrying operations. Currently (2022), Daimler Trucks offers the 437.4 heavy series and the 405 implement carrier series. Starting in 1951 having purchased the traditional Unimog from Boehringer, Daimler-Benz started making the Unimog S series in the mid-1950s and added light, medium and heavy series to the model lineup in the 1960s and 1970s, before they successively reduced the available models during the 1990s to end up with the modern implement carrier and the heavy series today.

Originally, the traditional Unimog 70200 was a rather small agricultural tractor, measuring just 3,520 mm in length. It was only offered as a Cabrio with a canvas roof. The engine power output of 25 DIN-PS (18.5 kW) proved to be insufficient for many applications. To accommodate customer needs, a longer wheelbase version, a proper cab and more powerful engines (up to 34 DIN-PS (25 kW)) were introduced soon after Daimler-Benz took over Unimog manufacture; the traditional Unimog evolved into its final stage, the 411-series. Yet, Daimler-Benz decided that an entirely new, more powerful version of the Unimog would be required to meet future customer expectations. This Unimog version would later be known as 406-series.: 12–14

The military Unimog S series is the first Unimog designed to be an offroad truck rather than a tractor, and it is the only series production Unimog that has an Otto engine.

With the introduction of the 406-series in 1962, Daimler-Benz laid the foundation for a completely new Unimog model family, the 406-based medium series (in the 1960s known as heavy series). It was produced until 1994. Unimogs belonging to the medium series are the series 403, 413, 406, 416, 426, and 419. These models were offered with three different wheelbases (2,380 mm, 2,900 mm, 3,400 mm) and two engines, the straight-four and straight-six direct injected Diesel engines OM 314 and OM 352, ranging from 54 DIN-PS to 110 DIN-PS (40 kW – 81 kW). The light series 421 and 431 share their frame design with the 411-series, but borrow their drivetrain and cab design from the 406-series, which is why they also count as 406-related Unimogs.: 11

The heavy series Unimogs were introduced in 1974, and first featured the edgy cab, which is still a design feature of the Unimog today. The first heavy series Unimog was the 425-series, which was available from 1976.: 85The 425 was available with a wheelbase of 2,810 mm, the 424 with 2,650 mm and 3,250 mm, and the 435 with 3,250 mm, 3,700 mm and 3,850 mm.

In 1988, after declining Unimog sales, Daimler-Benz launched a new strategy that was supposed to increase sales and make the Unimog more profitable, called "Unimog-Programm 1988". New models introduced with this programme were the new light series 407 and medium series 417, which ought to replace all Unimog 406-related series.: 119 407- and 417-series were replaced after just four years, in 1992, with the 408- and 418-series.: 134 in 2000, these two models were replaced with the current 405 implement carrier series, making the 437.4 and the 405 the only remaining Unimog series.

Like other trucks, but unlike agricultural tractors, the Unimog is a body-on-frame vehicle with short overhangs. The original Unimog was made with a plane ladder frame: 82 and a wheelbase of 1720 mm. Later, the wheelbase was extended several times to accommodate customer needs. Starting in the mid-1950s, with the introduction of the Unimog 404, the frame received a drop. Originally, this was done to make space for a spare tyre, but soon engineers found out that the new frame would improve the torsion performance, which is why all following Unimog series also received a frame with a drop.: 45 Several mounting brackets, additional cross members and tool boards were offered as factory options for the frame.: 79

The Unimog has live front and rear axles that have portal gears (portal axles). Such axles have a lifted axle centre, but the wheels" centre remains unchanged, meaning that a high ground clearance can be achieved with small wheels and tyres. Unlike "regular" trucks, the Unimog has coil springs with hydraulic shock absorbers rather than leaf springs, as coil springs provide more spring travel. The axles themselves have only one longitudinal pivot point each, the so-called torque tubes. The torque tubes contain the drive shafts and connect the axles" differential gearboxes to the Unimog gearbox, but being also parts of the suspension system, the torque tubes prevent longitudinal movement of the axles, whilst still allowing limited vertical movement. Lateral axle movement is prevented by panhard rods and transverse links. This design results in extreme axle angle offsets of up to 30° possible.: 36–40

A wide variety of wheels and tyres were available for the Unimog. Originally, the first Unimog was equipped with 6.5–18 in tyres designed for both on- and offroad use.: 48–49 Later, bigger wheels and tyres with different tread patterns were available, reaching from agricultural tractor tread patterns to massive bar tyre treads to low pressure ballon tyre treads. Until 1973, drum brakes were standard for all Unimogs, until they were replaced by disc brakes, however, until 1989, drum brakes remained an option for Unimogs of the 406-family.: 78 The steering system used to be a screw-and-nut system until 1970. Then it was replaced by a power assisted ball-and-nut system for the 406-series.: 77

The classical Unimog is rear-wheel drive vehicle, meaning that the rear axle is directly connected to the gearbox. Turning on front wheel drive automatically locks both axles, without torque compensation. The mechanical lever that turns on all wheel drive has a third position that locks front- and rear differentials. As of 1963, a pneumatic power switch was used instead of a lever. Due to the reduction gears inside the portal axles, the rotational frequency of the driveshafts inside the torque tubes is relatively high, meaning that the amount of torque they have to withstand is fairly low.: 23

Traditionally, the Unimog has a splitter gearbox. Over the years, three different base gearbox designs have been used, all following the same principle, and having four gears and two ranges (called groups) and an additional direction gear. Those designs were UG-1/xx, UG-2/xx, and UG-3/xx. UG is an abbreviation for Unimog-Getriebe (Unimog-Gearbox), the number after the slash resembles the input torque in kp·m (=9.80665 N·m).base gearbox UG-1 was a constant-mesh countershaft gearbox, it was then upgraded with synchroniser rings to a synchromesh gearbox. However, the synchromesh-version was only used for the 404-series, and the constant-mesh version remained the standard gearbox for the 411-series. In 1957, the synchromesh-version became an option for the 411-series, before it became the standard gearbox for all Unimogs in 1959.: 38–39 The following gearbox versions UG-2 and UG-3 were made as synchromesh versions only.

The initial Unimogs were equipped with passenger car engines, the first Unimog series to receive a truck engine was the 406-series in 1963.Diesel principle, except for engines used for the Unimog 404-series and the first four Unimog prototypes, which use the Otto principle. The following engines were used as of 1947, with M being Otto and OM being Diesel engines (the list is incomplete):

Traditionally, three different cab options were available for the Unimog: An open roof cab (Cabrio), single cab and double cab, with the single cab being the most popular. Because the Unimog was designed to be a better agricultural tractor, its original design did not include a closed cab (as agricultural tractors in Germany usually did not have a closed cab in the 1940s). The first Unimog series to be officially offered with a cab was the 401-series. However, the first cabs were made by Westfalia in Rheda-Wiedenbrück and then shipped to the Unimog plant in Gaggenau for assembly. These cabs are known as Westfalia type B or simply Froschauge ("frog"s eye"). Starting in 1957, a new cab with 30% more volume, called Westfalia type DvF, Typ D, verbreitertes Fahrerhaus (Type D, widened cab), was used. Both Westfalia cabs were fairly narrow and came with the problem of engine heat causing high cabin temperatures.: 44–47 The first Unimog that was designed with a cab was the series 406. Just for the purpose of manufacturing cabs, Daimler-Benz built a new 1000-Megapond-sheet-panel-press in the Unimog plant.: 60 It was planned that the double cab parts would also be produced with this press, instead, the double cabs were manufactured by Wackenhut in Nagold.: 89 In 1974, the current heavy-duty-series" cab was introduced. Its basic design has not been changed since.

The original Unimog was offered with a pneumatic system. This system was used for powering all auxiliary devices as well as the three-point linkages.: 77 As of October 1961, a hydraulics system became an option,: 76 and as of 1963, the hydraulics system became standard, but unlike the pneumatics system, the hydraulics system was made by Westinghouse Air Brake Company in Hannover. With the introduction of the hydraulics system, the pneumatics system was solely used for operating the brakes.: 27–28

Officially, the Unimog was never meant to be a military vehicle; in fact, Allied permission to develop the Unimog was granted only because Albert Friedrich, inventor of the Unimog, ensured that the Unimog would not have any military purpose.: 6 However, the Unimog has always been a military vehicle. 44 Unimogs of the first model, the Unimog 70200, served as combat engineer tractors in the Swiss army. They proved successful, and the Swiss army purchased 540 units of the 70200"s successor, the Unimog 2010. These early Swiss military vehicles were known as ″Dieseli″. The Dieseli-Unimogs remained in service until 1989.: 32 Officers of the French army, then occupying forces in Germany, noted the Unimog testing at the Sauberg in the early 1950s and considered the Unimog useful for patrolling purposes. Soon after, the French army purchased Unimogs of the series 2010 and 401. The Unimog proved to be so successful that Daimler-Benz was ordered to develop an entirely new Unimog just for military purposes. This new model was supposed to be a small 1.5-tonne truck, capable of carrying 10 to 12 soldiers on its bed, at a speed of up to 90 km/h, rather than being an agricultural tractor. Being a NATO member state, France demanded that the military Unimog would have an engine running on petrol.: 41 Daimler-Benz decided to use an Otto cycle engine, the M 180, displacing 2.2 litres, and producing 85 PS (63 kW).: 47 The military Unimog would later be known as Unimog 404 or Unimog S.

In total, 64,242 units of the Unimog 404 were produced, which makes it the Unimog with the highest production figure. 36,638 Unimog 404 were purchased by the German Bundeswehr.: 43 Apart from the Bundeswehr, many different military forces have either used the Unimog in the past or still make use of it today. In addition to the military series 404, several civilian models have been adapted for military use. In Argentina, the series 426, actually a version of the civilian series 416 produced under licence, was made for the Argentinian, Chilean, Peruvian and Bolivian military. In total, 2643 units of the series 426 were made. The Argentinian made Unimog 431, which was a licensed version of the civilian series 421, was also used as a military vehicle, mainly as a self-propelled howitzer. Another civilian Unimog that was mainly used a military vehicle, is the series 418.: 122

The military Unimogs are used as troop transportation vehicles, ambulances, and mobile command centers equipped with military communications equipment. The United States Marine Corps and United States Army uses the Unimog 419 as an engineer tractor, while the United States Army also uses Unimog vehicles to access remote installations. In total, 2416 Unimog 419 were made, and only used by United States Forces.: 81 Modern Unimogs also serve as military vehicles, and the current Unimog 437.4 chassis is used for the ATF Dingo. More than 5,500 Unimogs are in active service in the Turkish Armed Forces. They were produced by Mercedes-Benz Türk.

Unimogs are used by the German emergency management agency Technisches Hilfswerk (THW),Technical Relief Organization), by fire departmentsmunicipalities as utility vehicles. They can be used as material handlers, auxiliary power providers (generators), and equipment carriers.Alpine towns and districts are equipped with one or more Unimog snow blowers to clear narrow mountain roads that have drifted closed.

In construction, Unimogs are used as carriers of equipment and, with the optional extended cabin,backhoe, front loader, or other contracting equipment. On railroads, Unimogs are used as rail car movers and road-rail vehicles. They have also been used in mining areas, like seen in Gold Bridge, BC, Canada.

In agriculture, Unimogs are used to operate farm equipment. While most farm field implement operations are now performed by a tractor, Unimogs are used to haul produce, machinery and animals. They are also used around the farmyard to run chippers, grain augers, and conveyors.

Unimogs have been uncommon in North America because of differing vehicle regulations and requirements from those in Germany and Europe, and due to the lack of a North American sales and support network. Most Unimog models found in North America have been imported by individual dealers or independent enthusiasts.

In 2002 DaimlerChrysler tried to re-enter the North American market with the Unimog and engaged in four years of aggressive marketing, which included activities such as; truck and trade shows, exposure on the television show Freightliner truck dealerships.Caterpillar, John Deere, AM General, Sterling Trucks (also a Daimler AG subsidiary), and General Motors. After five years and selling only 184 Unimogs, Freightliner LLC exited the market. Daimler AG cited non-compliance with EPA07 emission requirements as the main reason for ceasing North American Sales.

Unimogs have been used in three kinds of competition: Dakar Rally and other desert rally competitions, mud bogging, and slow-moving Truck Trials over obstacles.

Unimogs have won the truck class of the Dakar in 1982 and 1986, the latter an unexpected victory as the vehicle participated for Honda, primarily to provide support for the motorcycles of the team.

In 1973 the Unimog department in Gaggenau also designed the MB Trac, a more tractor-like version. It was produced by Daimler-Benz until 1991, when the product line was sold to Werner Forst- und Industrietechnik, who continues to produce it as the

The Unimog also serves as a technical platform for armoured vehicles like the ATF Dingo, a mine-protected utility and reconnaissance vehicle used by the German and other European Armed Forces (e.g. Belgium) for territorial defence purposes as well as in international missions.

In late Autumn 1956, Daimler-Benz started developing a new military version of the Unimog, the Unimog SH. It was based on the Unimog S and had a rear engine (German: Heckmotor), hence the name Unimog SH.: 56 Until 1960, Daimler-Benz completed 24 Unimog SH and sent them to AB Landsverk for final assembly. Initially, the Belgian Army intended to purchase these vehicle for their police forces in the Belgian Congo, but only 9 vehicles were actually sold to the Belgian forces; the 15 remaining vehicles were purchased by the Irish Army in 1972.: 57 They were intended as a stop-gap vehicle for use until the first Panhard M3 VTT APCs entered service in 1972. The type had excellent off-road capability but poor on-road handling due to a high centre of gravity and several accidents occurred as a result. A four-man dismountable squad was carried, but space was cramped, and in any case a four-man detachment was far too small for any sort of realistic military purpose. Other considerations were that the FN MAG gunner"s position was too exposed. Eventually the Unimog Scout Cars arrived in Ireland in February 1972, their departure having been delayed by a local peace group who thought they were destined for the Provisional Irish Republican Army (PIRA). By mid-1978 all had been transferred to the Irish Army Reserve, the FCA. All were withdrawn by 1984, and two are preserved; one in the transport museum in Howth Co Dublin and one in the Muckleburgh Collection, England.

An updated version of the Unimog SH, the Unimog T was made for the German Bundeswehr in 1962. The German defence ministry decided not to purchase the Unimog T, which is why it was never put into series production.: 59 Further armoured vehicles developed in Germany using Unimog chassis are the UR-416, the Sonderwagen 4 and Condor 1 in Police service, and the ATF Dingo used by the Bundeswehr in Afghanistan. The French Aravis mine-protected vehicle, like the Dingo, based on the Special Chassis FGA 12.5. The Buffel, Mamba, RG-31, and RG-33 armoured personnel carriers from South Africa are based upon the Unimog driveline. The AV-VBL developed by Brazil"s Tectran is also an AFV family based on the Unimog.

Originally, the Unimog was developed in post-war Germany to be used as agricultural equipment. It was designed with equal-sized wheels, a mounting bracket in front, a hitch in the rear, and loading space in the center. This was to make it a multi-purpose vehicle that farmers could use in the field and on the highway.: 7

Albert Friedrich was granted permission to develop the Unimog in November 1945,: 6 and entered a production agreement with Erhard und Söhne (Erhard and Sons) in Schwäbisch Gmünd on 1 December 1945.: 7 Development began on 1 January 1946. Soon after, Heinrich Rößler, the Unimog lead designer, joined the development team. The first prototype was ready by the end of 1946. The early prototypes were equipped with the M 136 Otto engine, because the development of the OM 636 Diesel engine had not been finished.: 13 The prototypes were similar to the later series production models. The original track width of 1.270 m (4 ft 2 in) was equivalent to two potato rows.: 8

The 25-PS (18 kW) OM 636 Mercedes-Benz Diesel engine became standard equipment in the first production Unimogs at the end of 1947. The original emblem for the Unimog was a pair of ox horns in the shape of the letter U. The first 600 units of the 70200 series UnimogsBoehringer. This was done mainly for two reasons: Erhard und Söhne did not have the capacity to build the Unimogs and Boehringer (a former tool manufacturer) could evade dismantling.: 8

Daimler-Benz modified the Unimog for mass production to create the series 2010 and in 1951, started its manufacture in their Gaggenau plant in Baden-Württemberg, where production continued until 2002.

In 1953, the Unimog was updated and the three-pointed Mercedes star began to appear on the bonnet, replacing the Unimog ox horn emblem. The new model became known as the series 401.: 25 A new series 402 with a long wheelbase chassis (2,120 mm (83 in) instead of 1,720 mm (68 in)) also became available.

In 1955, the first Unimog 404 S series were produced. The primary customer of the 404 S was the Bundeswehr (literally Federal Defence, i.e. the West German Armed Forces), which was created in the mid-1950s in the era of the Cold War.: 43

The 406/416 middle series were produced beginning in 1963. They were equipped with the six-cylinder pre-combustion chamber Diesel engine OM 312 producing 65 PS (48 kW; 64 hp). The 406 and 416 are similar, The 416 having a longer 2,900 mm (114 in) wheelbase compared to 2,380 mm (94 in) for the 406. Starting in 1964, the 406-series was equipped with the direct injected OM 352 Diesel engine starting with 65 PS (48 kW; 64 hp) and going up to 84 PS (62 kW; 83 hp) (110 PS (81 kW) for the Unimog 416).: 104

Between the original Unimog and the middle series, Daimler-Benz developed a light series. The light series consisted of two separate Unimog series, the 421 and the 403. The 403, which basically is a 406-series with a 54 PS (40 kW; 53 hp) 3.8-litre four-cylinder engine, has a 2,380 mm (94 in) wheelbase and was later supplemented by the 413-series, which is a four-cylinder-version of the 416-series (long wheelbase (2,900 mm (114 in)) model). The 421 is the successor of the 411-series and has a 2,250 mm (89 in) wheelbase. It is powered by a 40 PS (29 kW; 39 hp) 2.2-litre passenger car Diesel engine.: 107

Argentina was the first country to manufacture the Unimog outside Germany. The first Unimog produced in the Mercedes-Benz Argentina S.A. factory in Gonzalez Catán, in the outskirts of Buenos Aires city, rolled off the assembly line on 1 September 1968.: 232

Despite originally being designed as an agricultural vehicle, the Unimog had more success as a multi-purpose tool carrier. To actually serve the agricultural market, Daimler-Benz designed a completely new agricultural tractor in 1972, the MB Trac. It is a body-on-frame design trac-tractor, has four big wheels of the same size, and all-wheel-drive, a slim bonnet, and an angular driver cab. In contrast to conventional tractors the cab is situated between the axles, similar to comparable four-wheel-drive tractors. There is no articulation between the front and rear sections, instead, the MB Trac has conventional steering.

In 1974, Mercedes-Benz presented the new Unimog U 120. It was the first model of the "heavy duty" Unimog series 425. The heavy duty series, or simply "heavy" series, extended the Unimog model lineup. The characteristic "edgy" bonnet introduced with the heavy Unimog series remains am Unimog style element to this day.

Manufacture of the series 435 for the Bundeswehr began in 1975, as a successor of the Unimog S 404. The 435 was characterized by a long wheelbase of 3,250 mm (128 in), 3,700 mm (146 in) or 3,850 mm (152 in) and shares its cab with the series 425.

The new 424 "middle" series of Unimogs was produced starting from 1976. They share the cab with the series-425 and are designated U 1000, U 1300/L, U 1500, and U 1700/L with 124 kW (166 hp; 169 PS) engine performance.

In the same period Daimler-Benz re-ordered the type designations for the older series. The classical round form series of the Unimog were now designated U 600/L, U 800/L, U 900 and U 1100/L. (The letter L stands for a long wheelbase, because most models were available in two wheelbase variants.)

The Unimog with the rounded driving cab became known as the light series. The new series with angular cab was divided by payload into a middle and heavy series. Some engines overlap – the Unimog nomenclature is not simple to understand (see below for notes on series names).

In the early 1990s, the new light models 408 (U 90) and 418 (U 110-U 140) with newly designed cabins were introduced to replace the predecessor models. The new very diagonal front portion gives the operator a good overview forward. The 408 features an asymmetric front bonnet, which is lower on the driver"s side. This is supposed to permit the driver a good overview. A new ladder frame and progressively working coil springs to improve the Unimog"s handling were implemented. In addition to that, the Unimog received a new tyre pressure adjustment system that can be operated whilst driving, an anti-skid system, new engines, and a "Servolock" mechanism for the hydraulic connection of implements.

In March 1994, Mercedes-Benz presented the design concept "Funmog", a luxury version of the Unimog, on the International Off-Road-Exhibition in Köln, Germany. It was based on the 408-series: 23 The Funmog features chrome bull bars, and air horns, but lacks hydraulics and is limited to a total mass of 5,000 kg.

Mercedes-Benz presented the Unimog 409 (officially called UX 100) in 1996.Multicar subsidiary of Hako GmbH, who specialize in vehicles of this kind and size.

In August 2002 production ended in the Gaggenau plant after 51 years and more than 320,000 Unimogs being made, and started up in Mercedes-Benz"s truck manufacturing plant in Wörth am Rhein. The U 3000, U 4000 and U 5000 models (UHN 437.4 series) were introduced at the same time.

At the Dubai Motor Show in December 2005, the "Unimog U 500 Black Edition" premiered as an offering to wealthy desert-dwellers. It is a similar luxury offering comparable to the Funmog.

At the IAA 2006 commercial vehicle show in Hanover a new UnimogU 20 was presented, which was to be available at the end of 2007. The most striking feature is the cab over design with no vestigial front bonnet characteristic of the traditional Unimog. It has a total mass of 7,500 kg up to 8,500 kg. The underlying technology comes from the U 300. The driving cab is from the new Brazilian Accelo light truck (Caminhões Leves) series. The wheelbase is shortened to 2,700 mm (106 in).

Unimog series numbers like 401, 406, or 425 in this article are the factory numerical designation (in German "Baumuster", literally Construction Pattern). Unimogs also have a sales model number like U 80, U 120, or U 1350. Each series can have several model numbers, as they are equipped with different engines.

In this article, the terms Otto cycle engine and Diesel cycle engine are used to differentiate between a traditional petrol engine and a traditional Diesel engine. This is because the original Unimog does not only have a Diesel engine that can burn petrol (precombustion chamber design), but also used to require petrol as a fuel additive in winter to prevent the fuel from gelling. Furthermore, many German military vehicles (such as the Unimog S) have petrol engines, but several military petrol engines use the Diesel principle.

Hydraulic pumps are mechanisms in hydraulic systems that move hydraulic fluid from point to point initiating the production of hydraulic power. Hydraulic pumps are sometimes incorrectly referred to as “hydrolic” pumps.

They are an important device overall in the hydraulics field, a special kind of power transmission which controls the energy which moving fluids transmit while under pressure and change into mechanical energy. Other kinds of pumps utilized to transmit hydraulic fluids could also be referred to as hydraulic pumps. There is a wide range of contexts in which hydraulic systems are applied, hence they are very important in many commercial, industrial, and consumer utilities.

“Power transmission” alludes to the complete procedure of technologically changing energy into a beneficial form for practical applications. Mechanical power, electrical power, and fluid power are the three major branches that make up the power transmission field. Fluid power covers the usage of moving gas and moving fluids for the transmission of power. Hydraulics are then considered as a sub category of fluid power that focuses on fluid use in opposition to gas use. The other fluid power field is known as pneumatics and it’s focused on the storage and release of energy with compressed gas.

"Pascal"s Law" applies to confined liquids. Thus, in order for liquids to act hydraulically, they must be contained within a system. A hydraulic power pack or hydraulic power unit is a confined mechanical system that utilizes liquid hydraulically. Despite the fact that specific operating systems vary, all hydraulic power units share the same basic components. A reservoir, valves, a piping/tubing system, a pump, and actuators are examples of these components. Similarly, despite their versatility and adaptability, these mechanisms work together in related operating processes at the heart of all hydraulic power packs.

The hydraulic reservoir"s function is to hold a volume of liquid, transfer heat from the system, permit solid pollutants to settle, and aid in releasing moisture and air from the liquid.

Mechanical energy is changed to hydraulic energy by the hydraulic pump. This is accomplished through the movement of liquid, which serves as the transmission medium. All hydraulic pumps operate on the same basic principle of dispensing fluid volume against a resistive load or pressure.

Hydraulic valves are utilized to start, stop, and direct liquid flow in a system. Hydraulic valves are made of spools or poppets and can be actuated hydraulically, pneumatically, manually, electrically, or mechanically.

The end result of Pascal"s law is hydraulic actuators. This is the point at which hydraulic energy is transformed back to mechanical energy. This can be accomplished by using a hydraulic cylinder to transform hydraulic energy into linear movement and work or a hydraulic motor to transform hydraulic energy into rotational motion and work. Hydraulic motors and hydraulic cylinders, like hydraulic pumps, have various subtypes, each meant for specific design use.

The essence of hydraulics can be found in a fundamental physical fact: fluids are incompressible. (As a result, fluids more closely resemble solids than compressible gasses) The incompressible essence of fluid allows it to transfer force and speed very efficiently. This fact is summed up by a variant of "Pascal"s Principle," which states that virtually all pressure enforced on any part of a fluid is transferred to every other part of the fluid. This scientific principle states, in other words, that pressure applied to a fluid transmits equally in all directions.

Furthermore, the force transferred through a fluid has the ability to multiply as it moves. In a slightly more abstract sense, because fluids are incompressible, pressurized fluids should keep a consistent pressure just as they move. Pressure is defined mathematically as a force acting per particular area unit (P = F/A). A simplified version of this equation shows that force is the product of area and pressure (F = P x A). Thus, by varying the size or area of various parts inside a hydraulic system, the force acting inside the pump can be adjusted accordingly (to either greater or lesser). The need for pressure to remain constant is what causes force and area to mirror each other (on the basis of either shrinking or growing). A hydraulic system with a piston five times larger than a second piston can demonstrate this force-area relationship. When a force (e.g., 50lbs) is exerted on the smaller piston, it is multiplied by five (e.g., 250 lbs) and transmitted to the larger piston via the hydraulic system.

Hydraulics is built on fluids’ chemical properties and the physical relationship between pressure, area, and force. Overall, hydraulic applications allow human operators to generate and exert immense mechanical force with little to no physical effort. Within hydraulic systems, both oil and water are used to transmit power. The use of oil, on the other hand, is far more common, owing in part to its extremely incompressible nature.

Pressure relief valves prevent excess pressure by regulating the actuators’ output and redirecting liquid back to the reservoir when necessary. Directional control valves are used to change the size and direction of hydraulic fluid flow.

While hydraulic power transmission is remarkably useful in a wide range of professional applications, relying solely on one type of power transmission is generally unwise. On the contrary, the most efficient strategy is to combine a wide range of power transmissions (pneumatic, hydraulic, mechanical, and electrical). As a result, hydraulic systems must be carefully embedded into an overall power transmission strategy for the specific commercial application. It is necessary to invest in locating trustworthy and skilled hydraulic manufacturers/suppliers who can aid in the development and implementation of an overall hydraulic strategy.

The intended use of a hydraulic pump must be considered when selecting a specific type. This is significant because some pumps may only perform one function, whereas others allow for greater flexibility.

The pump"s material composition must also be considered in the application context. The cylinders, pistons, and gears are frequently made of long-lasting materials like aluminum, stainless steel, or steel that can withstand the continuous wear of repeated pumping. The materials must be able to withstand not only the process but also the hydraulic fluids. Composite fluids frequently contain oils, polyalkylene glycols, esters, butanol, and corrosion inhibitors (though water is used in some instances). The operating temperature, flash point, and viscosity of these fluids differ.

In addition to material, manufacturers must compare hydraulic pump operating specifications to make sure that intended utilization does not exceed pump abilities. The many variables in hydraulic pump functionality include maximum operating pressure, continuous operating pressure, horsepower, operating speed, power source, pump weight, and maximum fluid flow. Standard measurements like length, rod extension, and diameter should be compared as well. Because hydraulic pumps are used in lifts, cranes, motors, and other heavy machinery, they must meet strict operating specifications.

It is critical to recall that the overall power generated by any hydraulic drive system is influenced by various inefficiencies that must be considered in order to get the most out of the system. The presence of air bubbles within a hydraulic drive, for example, is known for changing the direction of the energy flow inside the system (since energy is wasted on the way to the actuators on bubble compression). Using a hydraulic drive system requires identifying shortfalls and selecting the best parts to mitigate their effects. A hydraulic pump is the "generator" side of a hydraulic system that initiates the hydraulic procedure (as opposed to the "actuator" side that completes the hydraulic procedure). Regardless of disparities, all hydraulic pumps are responsible for displacing liquid volume and transporting it to the actuator(s) from the reservoir via the tubing system. Some form of internal combustion system typically powers pumps.

While the operation of hydraulic pumps is normally the same, these mechanisms can be split into basic categories. There are two types of hydraulic pumps to consider: gear pumps and piston pumps. Radial and axial piston pumps are types of piston pumps. Axial pumps produce linear motion, whereas radial pumps can produce rotary motion. The gear pump category is further subdivided into external gear pumps and internal gear pumps.

Each type of hydraulic pump, regardless of piston or gear, is either double-action or single-action. Single-action pumps can only pull, push, or lift in one direction, while double-action pumps can pull, push, or lift in multiple directions.

Vane pumps are positive displacement pumps that maintain a constant flow rate under varying pressures. It is a pump that self-primes. It is referred to as a "vane pump" because the effect of the vane pressurizes the liquid.

This pump has a variable number of vanes mounted onto a rotor that rotates within the cavity. These vanes may be variable in length and tensioned to maintain contact with the wall while the pump draws power. The pump also features a pressure relief valve, which prevents pressure rise inside the pump from damaging it.

Internal gear pumps and external gear pumps are the two main types of hydraulic gear pumps. Pumps with external gears have two spur gears, the spurs of which are all externally arranged. Internal gear pumps also feature two spur gears, and the spurs of both gears are internally arranged, with one gear spinning around inside the other.

Both types of gear pumps deliver a consistent amount of liquid with each spinning of the gears. Hydraulic gear pumps are popular due to their versatility, effectiveness, and fairly simple design. Furthermore, because they are obtainable in a variety of configurations, they can be used in a wide range of consumer, industrial, and commercial product contexts.

Hydraulic ram pumps are cyclic machines that use water power, also referred to as hydropower, to transport water to a higher level than its original source. This hydraulic pump type is powered solely by the momentum of moving or falling water.

Ram pumps are a common type of hydraulic pump, especially among other types of hydraulic water pumps. Hydraulic ram pumps are utilized to move the water in the waste management, agricultural, sewage, plumbing, manufacturing, and engineering industries, though only about ten percent of the water utilized to run the pump gets to the planned end point.

Despite this disadvantage, using hydropower instead of an external energy source to power this kind of pump makes it a prominent choice in developing countries where the availability of the fuel and electricity required to energize motorized pumps is limited. The use of hydropower also reduces energy consumption for industrial factories and plants significantly. Having only two moving parts is another advantage of the hydraulic ram, making installation fairly simple in areas with free falling or flowing water. The water amount and the rate at which it falls have an important effect on the pump"s success. It is critical to keep this in mind when choosing a location for a pump and a water source. Length, size, diameter, minimum and maximum flow rates, and speed of operation are all important factors to consider.

Hydraulic water pumps are machines that move water from one location to another. Because water pumps are used in so many different applications, there are numerous hydraulic water pump variations.

Water pumps are useful in a variety of situations. Hydraulic pumps can be used to direct water where it is needed in industry, where water is often an ingredient in an industrial process or product. Water pumps are essential in supplying water to people in homes, particularly in rural residences that are not linked to a large sewage circuit. Water pumps are required in commercial settings to transport water to the upper floors of high rise buildings. Hydraulic water pumps in all of these situations could be powered by fuel, electricity, or even by hand, as is the situation with hydraulic hand pumps.

Water pumps in developed economies are typically automated and powered by electricity. Alternative pumping tools are frequently used in developing economies where dependable and cost effective sources of electricity and fuel are scarce. Hydraulic ram pumps, for example, can deliver water to remote locations without the use of electricity or fuel. These pumps rely solely on a moving stream of water’s force and a properly configured number of valves, tubes, and compression chambers.

Electric hydraulic pumps are hydraulic liquid transmission machines that use electricity to operate. They are frequently used to transfer hydraulic liquid from a reservoir to an actuator, like a hydraulic cylinder. These actuation mechanisms are an essential component of a wide range of hydraulic machinery.

There are several different types of hydraulic pumps, but the defining feature of each type is the use of pressurized fluids to accomplish a job. The natural characteristics of water, for example, are harnessed in the particular instance of hydraulic water pumps to transport water from one location to another. Hydraulic gear pumps and hydraulic piston pumps work in the same way to help actuate the motion of a piston in a mechanical system.

Despite the fact that there are numerous varieties of each of these pump mechanisms, all of them are powered by electricity. In such instances, an electric current flows through the motor, which turns impellers or other devices inside the pump system to create pressure differences; these differential pressure levels enable fluids to flow through the pump. Pump systems of this type can be utilized to direct hydraulic liquid to industrial machines such as commercial equipment like elevators or excavators.

Hydraulic hand pumps are fluid transmission machines that utilize the mechanical force generated by a manually operated actuator. A manually operated actuator could be a lever, a toggle, a handle, or any of a variety of other parts. Hydraulic hand pumps are utilized for hydraulic fluid distribution, water pumping, and various other applications.

Hydraulic hand pumps may be utilized for a variety of tasks, including hydraulic liquid direction to circuits in helicopters and other aircraft, instrument calibration, and piston actuation in hydraulic cylinders. Hydraulic hand pumps of this type use manual power to put hydraulic fluids under pressure. They can be utilized to test the pressure in a variety of devices such as hoses, pipes, valves, sprinklers, and heat exchangers systems. Hand pumps are extraordinarily simple to use.

Each hydraulic hand pump has a lever or other actuation handle linked to the pump that, when pulled and pushed, causes the hydraulic liquid in the pump"s system to be depressurized or pressurized. This action, in the instance of a hydraulic machine, provides power to the devices to which the pump is attached. The actuation of a water pump causes the liquid to be pulled from its source and transferred to another location. Hydraulic hand pumps will remain relevant as long as hydraulics are used in the commerce industry, owing to their simplicity and easy usage.

12V hydraulic pumps are hydraulic power devices that operate on 12 volts DC supplied by a battery or motor. These are specially designed processes that, like all hydraulic pumps, are applied in commercial, industrial, and consumer places to convert kinetic energy into beneficial mechanical energy through pressurized viscous liquids. This converted energy is put to use in a variety of industries.

Hydraulic pumps are commonly used to pull, push, and lift heavy loads in motorized and vehicle machines. Hydraulic water pumps may also be powered by 12V batteries and are used to move water out of or into the desired location. These electric hydraulic pumps are common since they run on small batteries, allowing for ease of portability. Such portability is sometimes required in waste removal systems and vehiclies. In addition to portable and compact models, options include variable amp hour productions, rechargeable battery pumps, and variable weights.

While non rechargeable alkaline 12V hydraulic pumps are used, rechargeable ones are much more common because they enable a continuous flow. More considerations include minimum discharge flow, maximum discharge pressure, discharge size, and inlet size. As 12V batteries are able to pump up to 150 feet from the ground, it is imperative to choose the right pump for a given use.

Air hydraulic pumps are hydraulic power devices that use compressed air to stimulate a pump mechanism, generating useful energy from a pressurized liquid. These devices are also known as pneumatic hydraulic pumps and are applied in a variety of industries to assist in the lifting of heavy loads and transportation of materials with minimal initial force.

Air pumps, like all hydraulic pumps, begin with the same components. The hydraulic liquids, which are typically oil or water-based composites, require the use of a reservoir. The fluid is moved from the storage tank to the hydraulic cylinder via hoses or tubes connected to this reservoir. The hydraulic cylinder houses a piston system and two valves. A hydraulic fluid intake valve allows hydraulic liquid to enter and then traps it by closing. The discharge valve is the point at which the high pressure fluid stream is released. Air hydraulic pumps have a linked air cylinder in addition to the hydraulic cylinder enclosing one end of the piston.

The protruding end of the piston is acted upon by a compressed air compressor or air in the cylinder. When the air cylinder is empty, a spring system in the hydraulic cylinder pushes the piston out. This makes a vacuum, which sucks fluid from the reservoir into the hydraulic cylinder. When the air compressor is under pressure, it engages the piston and pushes it deeper into the hydraulic cylinder and compresses the liquids. This pumping action is repeated until the hydraulic cylinder pressure is high enough to forcibly push fluid out through the discharge check valve. In some instances, this is connected to a nozzle and hoses, with the important part being the pressurized stream. Other uses apply the energy of this stream to pull, lift, and push heavy loads.

Hydraulic piston pumps transfer hydraulic liquids through a cylinder using plunger-like equipment to successfully raise the pressure for a machine, enabling it to pull, lift, and push heavy loads. This type of hydraulic pump is the power source for heavy-duty machines like excavators, backhoes, loaders, diggers, and cranes. Piston pumps are used in a variety of industries, including automotive, aeronautics, power generation, military, marine, and manufacturing, to mention a few.

Hydraulic piston pumps are common due to their capability to enhance energy usage productivity. A hydraulic hand pump energized by a hand or foot pedal can convert a force of 4.5 pounds into a load-moving force of 100 pounds. Electric hydraulic pumps can attain pressure reaching 4,000 PSI. Because capacities vary so much, the desired usage pump must be carefully considered. Several other factors must also be considered. Standard and custom configurations of operating speeds, task-specific power sources, pump weights, and maximum fluid flows are widely available. Measurements such as rod extension length, diameter, width, and height should also be considered, particularly when a hydraulic piston pump is to be installed in place of a current hydraulic piston pump.

Hydraulic clutch pumps are mechanisms that include a clutch assembly and a pump that enables the user to apply the necessary pressure to disengage or engage the clutch mechanism. Hydraulic clutches are crafted to either link two shafts and lock them together to rotate at the same speed or detach the shafts and allow them to rotate at different speeds as needed to decelerate or shift gears.

Hydraulic pumps change hydraulic energy to mechanical energy. Hydraulic pumps are particularly designed machines utilized in commercial, industrial, and residential areas to generate useful energy from different viscous liquids pressurization. Hydraulic pumps are exceptionally simple yet effective machines for moving fluids. "Hydraulic" is actually often misspelled as "Hydralic". Hydraulic pumps depend on the energy provided by hydraulic cylinders to power different machines and mechanisms.

There are several different types of hydraulic pumps, and all hydraulic pumps can be split into two primary categories. The first category includes hydraulic pumps that function without the assistance of auxiliary power sources such as electric motors and gas. These hydraulic pump types can use the kinetic energy of a fluid to transfer it from one location to another. These pumps are commonly called ram pumps. Hydraulic hand pumps are never regarded as ram pumps, despite the fact that their operating principles are similar.

The construction, excavation, automotive manufacturing, agriculture, manufacturing, and defense contracting industries are just a few examples of operations that apply hydraulics power in normal, daily procedures. Since hydraulics usage is so prevalent, hydraulic pumps are unsurprisingly used in a wide range of machines and industries. Pumps serve the same basic function in all contexts where hydraulic machinery is used: they transport hydraulic fluid from one location to another in order to generate hydraulic energy and pressure (together with the actuators).

Elevators, automotive brakes, automotive lifts, cranes, airplane flaps, shock absorbers, log splitters, motorboat steering systems, garage jacks and other products use hydraulic pumps. The most common application of hydraulic pumps in construction sites is in big hydraulic machines and different types of "off-highway" equipment such as excavators, dumpers, diggers, and so on. Hydraulic systems are used in other settings, such as offshore work areas and factories, to power heavy machinery, cut and bend material, move heavy equipment, and so on.

Fluid’s incompressible nature in hydraulic systems allows an operator to make and apply mechanical power in an effective and efficient way. Practically all force created in a hydraulic system is applied to the intended target.

Because of the relationship between area, pressure, and force (F = P x A), modifying the force of a hydraulic system is as simple as changing the size of its components.

Hydraulic systems can transfer energy on an equal level with many mechanical and electrical systems while being significantly simpler in general. A hydraulic system, for example, can easily generate linear motion. On the contrary, most electrical and mechanical power systems need an intermediate mechanical step to convert rotational motion to linear motion.

Hydraulic systems are typically smaller than their mechanical and electrical counterparts while producing equivalents amounts of power, providing the benefit of saving physical space.

Hydraulic systems can be used in a wide range of physical settings due to their basic design (a pump attached to actuators via some kind of piping system). Hydraulic systems could also be utilized in environments where electrical systems would be impractical (for example underwater).

By removing electrical safety hazards, using hydraulic systems instead of electrical power transmission improves relative safety (for example explosions, electric shock).

The amount of power that hydraulic pumps can generate is a significant, distinct advantage. In certain cases, a hydraulic pump could generate ten times the power of an electrical counterpart. Some hydraulic pumps (for example, piston pumps) cost more than the ordinary hydraulic component. These drawbacks, however, can be mitigated by the pump"s power and efficiency. Despite their relatively high cost, piston pumps are treasured for their strength and capability to transmit very viscous fluids.

Handling hydraulic liquids is messy, and repairing leaks in a hydraulic pump can be difficult. Hydraulic liquid that leaks in hot areas may catch fire. Hydraulic lines that burst may cause serious injuries. Hydraulic liquids are corrosive as well, though some are less so than others. Hydraulic systems need frequent and intense maintenance. Parts with a high factor of precision are frequently required in systems. If the power is very high and the pipeline cannot handle the power transferred by the liquid, the high pressure received by the liquid may also cause work accidents.

Even though hydraulic systems are less complex than electrical or mechanical systems, they are still complex systems that should be handled with caution. Avoiding physical contact with hydraulic systems is an essential safety precaution when engaging with them. Even when a hydraulic machine is not in use, active liquid pressure within the system can be a hazard.

Inadequate pumps can cause mechanical failure in the place of work that can have serious and costly consequences. Although pump failure has historically been unpredictable, new diagnostic technology continues to improve on detecting methods that previously relied solely on vibration signals. Measuring discharge pressures enables manufacturers to forecast pump wear more accurately. Discharge sensors are simple to integrate into existing systems, increasing the hydraulic pump"s safety and versatility.

Hydraulic pumps are devices in hydraulic systems that move hydraulic fluid from point to point, initiating hydraulic power production. They are an important device overall in the hydraulics field, a special kind of power transmission that controls the energy which moving fluids transmit while under pressure and change into mechanical energy. Hydraulic pumps are divided into two categories namely gear pumps and piston pumps. Radial and axial piston pumps are types of piston pumps. Axial pumps produce linear motion, whereas radial pumps can produce rotary motion. The construction, excavation, automotive manufacturing, agriculture, manufacturing, and defense contracting industries are just a few examples of operations that apply hydraulics power in normal, daily procedures.
