Wire rope is constructed of multiple strands of wire that are twisted and braided together to form a spiral design or helix. Once the separate wires are shaped into a solid form, they become a single wire with greater strength because the individual wires equalize pressure and have greater flexibility than the individual strands.

To further enhance the strength of wire ropes, they are grouped and wound together to produce cables, which adds to their usefulness as a means of support, ability to lift, and give structural stability.

A key factor in wire rope is the lay of the strands, which can be regular or lang. With regular lay, or right and ordinary lay, the strands are wound from left to right with the wires laid in the opposite direction of the lay of the strands. With lang lay, the wires are wound in the same direction.

The structure and design of wire rope produces a final product that has superior strength, excellent strength flexibility, and the ability to handle constant bending stress as well as being weather resistant.

Wire rope is one of those products that has found a place in a wide variety of industries since it can be adapted and shaped to fit several applications. It can be found as a tow cable for boats and airplanes or in the movie industry as a harness for stunt artists. The varied uses of wire rope have made it an essential part of operations that require a rope with strength, endurance, and flexibility.

In the aerospace industry, wire ropes, or Bowden cables, connect pedals and levers in the airplane cockpit to send power to aircraft systems to control the airplane. The things that are controlled by wire ropes are propeller pitch, cowl flaps, and throttle. Wire ropes on aircraft are insulated to avoid vibrations.

Wire rope is extensively used in the auto industry for a wide variety of applications due to its versatility and strength. It is used for raising windows and opening and closing sunroofs. Other uses include steering wheels, cables, exhausts, springs, sunroofs, doors, and seat components. In the manufacturing process, wire rope is used to hoist vehicles, move large body parts, and on hoists and cranes.

The construction industry has a greatest reliance on wire rope because of the need to lift and lower heavy loads. Wire rope used in construction must have extremely high strength and exceptional performance for safety reasons and efficiency. Larger versions of wire rope are used for suspension bridges and supporting concrete columns.

The main use of wire rope in food processing is for lifting, moving loads, and other heavy tasks. Finished products or raw materials require being moved in storage units and processing centers. The strength and endurance of wire rope makes it possible to move these materials. Wire rope for food processing must be able to withstand regular chemical cleaning.

As with other industries, the oil and gas industry needs strong and reliable equipment for moving heavy equipment. In ocean drilling, machinery is dropped into the ocean using wire rope to securely hold devices to be dropped to extreme depths. Wire ropes are designed to withstand the extreme pressure and stress required. A further use of wire ropes for drilling operations is to maintain stability in the drilling lines. One of the unique features of oil rig wire rope is its length, which can exceed 10,000 feet.

A very common use for wire rope is mooring and towing of sea and freshwater boats and vessels. In the shipbuilding industry, wire rope is used to secure lifeboats as well as lower them into the water. On sailboats, wire rope is used to lift and lower sails. The benefit of using wire rope is its resistance to corrosion and rust caused by salt water and ocean mist.

The skiing industry, much like heavy equipment industries, uses wire rope to hold cars, lifts, or chairs to transport skiers up the mountain. This type of wire rope comes in several varieties depending on the size of the mountain. The benefits of wire rope for skiing is its dependability, guaranteed safety, and reliability. The main challenge of wire rope for use in sports is the weather conditions it must endure.

Since the beginnings of amusement parks, wire rope has been an essential part of attraction construction. It is used to bring roller coaster cars to the top of the ride, hold swings, and pull various vehicles through attractions. One of the main concerns of public amusement parks is safety since rides are filled with powerful machinery designed to operate continuously.

Making the dangerous and exciting shots in movies requires well planned safety precautions. One of the aspects of that planning is wire rope that is designed to protect performers when they are engaged in dangerous and life threatening shots. Dependable wire ropes are ideal since they have the flexibility, strength, endurance, and versatility to be adapted to any conditions.

In architecture and design, wire rope has been used for guard rails, balustrades, and roof construction. In innovative green buildings where plants grow along the surface of the building, the plants grow along specially designed vertical wire ropes that are capable of withstanding weather conditions.

A common use of wire rope is in railings, which are safe, durable, and provide a pleasing aesthetic appeal. The use of wire rope for railings provides protection without obstructing the view from a building. This aspect of wire rope is one of the reasons that it is used for large architectural projects since it blends into the structure without interiors with the architectural design.

The types of wire rope are determined by the number of wires in each strand and how many are in the rope, which is defined by a two number system with the first number being the number of wires and the second being the number of wires in each strand. For example, a 6x19 wire rope has 6 wires in 19 strands.

There are a wide variety of products that are produced using wire rope. The demand for wire rope products is due to its strength, durability, and reliability. Since the basic purpose of wire rope is to lift and move heavy materials and items, the most common type of wire rope product is the wire rope sling.

Though the construction of wire rope slings is very similar for all types, there are certain variations applied to slings to adjust them to fit different applications. Slings are configured in various ways to fit different types of loads. These changes are referred to as hitches.

Bridle Hitch: The multiple leg or bridle hitch style has more than one wire rope sling attached to equalize the load and control balance. They reduce load damage by using fixed points on the load and offer easier rigging when hooked into fixed lifting points. .

Single Part Wire Rope Sling: The eye for a single part wire rope sling is formed by looping the wire rope back on to the rope. The end of the rope is attached by a clamp or being woven by hand or mechanically into the rope body. Single part wire rope slings use a single wire rope to produce the sling.

Braided Wire Rope Sling: A braided wire rope sling is made by braiding wire ropes to form a sling. The increased number of strands enhances the strength of the sling and its load capacity. Braiding can be done with three to nine wire ropes.

Cable Laid Wire Rope Sling: Cable laid wire rope slings are made from combining several smaller wire ropes to form a flexible, easy to handle, and kink resistant sling.

Woven Eye Wire Rope Sling: For the woven eye version of a wire rope sling, the eye is formed by weaving the wire rope into itself after forming the loop. It is designed to reduce the chance of the sling catching or being hung up when lifting.

Thimble Wire Rope Sling: To add to the strength of wire rope slings and lessen the stress on a small area of the eye, a thimble, a U shaped piece into which the wire rope fits, is placed in the eye, which helps the sling to retain its natural shape. The thimble is positioned to prevent the hook or load from coming in contact with the wire rope.

Endless Wire Rope Sling:Endless wire rope slings are adaptable slings without a set wear point. They can be manufactured in a wide range of sizes and are used in applications where headroom may be a problem. Endless wire rope slings are made by splicing the ends of a piece of wire rope together or by tucking strand ends into the body to form a core with a tucked position the opposite of the core position. They are also referred to as grommet wire rope slings.

Coiled wire rope is made from bundles of small metal wires that are twisted into a coil. It comes in many varieties and is easy to store since it does not require a spool. Coiled wire rope is produced in coils. When it is not in use, it springs back into a coil, which makes it easy to handle.

Cable wire rope is a type of high strength rope, made of several individual filaments. These filaments are twisted into strands and helically wrapped around a core. One of the most common types of wire rope cable is steel cable.

Push pull wire rope assemblies are used to send force and are used in the aircraft, exercise, medical, automotive, and office equipment industries. Unlike using a single heavy wire, push pull assemblies made with wire rope are stiffer and have a larger bend radii for smoother motion of the wire.

Wire rope assemblies include wire rope and various parts and components that have been added to the wire rope to enhance its function. The connectors for a wire rope assembly are designed to connect the assembly to hooks, equipment, or machines as well as other wire rope assemblies. The central part of a wire rope assembly is the wire rope, which determines the type and kind of work the assembly can perform.

Wire rope lanyards are a standard wire rope product that have a multitude of uses. They are produced using the same process that is used to produce wire rope with the same numbering categorizing system. Lanyards are used to hold fasteners, hardware, or components to prevent loss of an item or prevent injury.

In many ways, wire rope is a form of machine with multiple moving parts. Normally, when we think of a machine, we imagine a device with a motor, drives, and gears. Wire rope does not have any of those components but does fit the definition of being a complex mechanism. It has moving parts that work together to move heavy materials and loads.

The main function of wire rope is to do heavy lifting, which is very dependent on wire rope slings. The type of sling is determined by the quality of the wire rope used to form them and whether several ropes have been braided or wound together.

Wire is the smallest part of wire rope but makes up the various strands. The composition of the wire can be steel, iron, stainless steel, copper, or other types of metal wires and are produced in different grades. The individual wires can be coated or bright, meaning uncoated.

Strands are sets of wires that are twisted together and are placed in a helical pattern around the core. The size of the wire determines its abrasive qualities with larger wires being more abrasive and less flexible than smaller ones.

The core is the center of the wire rope and serves as a support for the strands and helps the wire rope keep its position when it is under stress or bearing a load.

Lubrication is applied during the manufacturing process to reduce friction between the wires and strands as well as protection from corrosion and rust. The tight winding of the wires enhances the ability of the wire rope to retain the lubrication which is essential to its longevity.

The purpose of applying lubricant is to limit the friction between the cables to increase the useful life of the wire rope. In certain applications, such as space travel, lubricants can be hazardous and cause equipment to malfunction. In those instances, non-lubricated wire rope is used, which is referred to as dry wire rope or cable.

Of all of the products that are made from wire rope, slings are the most common and widely used. These looped wire ropes come in different varieties and grades depending on the type of wire used. Also, to enhance wire sling performance, several wire ropes may be wound together to form a sturdier and more reliable sling.

Flemish splicing is a method for repairing a wire rope and involves breaking the wire rope in half and tying it back together. In the Flemish method, the wire rope is tied back on itself and swaged down a sleeve over the unbroken wire rope to create the new eye.

Prior to placing the wire rope into the holding device used to shape the eye, a steel compression sleeve is placed on the rope, which will be used to secure and hold the eye.

Once the proper size is achieved, the unwound strands are rewound in the reverse order of their former positioning. If the wire rope has a right hand lay, it is rewound using a left hand lay. The opposite is true if the wire rope has a left hand lay, then it is rewound using a right hand lay. By using this technique, a friction mold is formed for the splicing of the sling.

Anti-rotational wire rope resists the forces of rotation by having opposing layers of helical stands. By winding the wire rope with oppositional strands, the wire rope is guaranteed to not unwind in clockwise or counterclockwise directions. The key to anti-rotational wire rope is to ensure that the outer diameter is static.

In the manufacture of anti-rotational wire rope, counter stranded filaments have vacant spaces between them. To make the wire rope anti-rotational, it is tightly twisted in the counterclockwise direction, which tightens the spaces between the filaments. If the wire rope is turned in a counterclockwise direction, the strands tighten around each other creating a spring force.

The tails and stray wires of the wire rope have to be straightened and properly formed before applying the compression sleeve. Once the sleeve has been placed, it is carefully checked to be sure that it is accurately engaged.

Prior to placing the wire rope sling in the swaging die, the die has to be thoroughly lubricated. Once the die is set, the wire rope‘s compression sleeve and the wire rope are compressed using several hundred thousand pounds of force. The swaging process alters the dimensions of the wire rope and compression sleeve to form a tight connection for the correct diameter for the sling connection. As force is applied, the compression sleeve is turned so that pressure is evenly applied.

There are several types of metal wires that are used to produce wire rope, which include steel, stainless steel, galvanized, aluminum, nickel alloy, bronze, copper, and titanium. Carbon steel is the most common type of wire rope material.

Wire ropes are made using uncoated bright wire, which is high-carbon steel. The type of steel depends on the requirements of the wire and its tensile strength and its fatigue and wear resistance.

Galvanized wire rope is treated with zinc to prevent corrosion and can be used in harsh conditions and environments. It is a cost effective alternative to stainless steel but does not have the same corrosion resistance. Galvanized wire rope is stronger than stainless steel of the same grade and size. Vinyl coated galvanized wire rope is easy to handle and flexible.

Stainless steel wire rope is corrosion and rust resistant. It is available in types 316 and 304 with 316 having greater corrosion resistance. Stainless steel wire rope can be used for marine applications, acidic environments, and other demanding conditions. It is produced with the appropriate tolerances and composition to meet the needs of the application.

Multiple strands of copper are braided into a round hollow shape, which is pressed into the desired width and thickness. Copper wire rope has exceptional flexibility, an exceptional life span and can be used as part of electrical components.

Bronze wire rope inhibits sparking and is corrosion resistant. It is made from preformed wire to ensure that it maintains its shape and does not unravel when cut. Bronze wire rope is abrasion resistant and very flexible with a crush resistant core.

Inconel wire can be used in applications that reach temperatures as high as 2000° F and is oxidation and corrosion resistant. It is non-magnetic and has excellent resistance to chloride based corrosion cracking. Inconel wire rope can be used with nuclear generators and chemical and food processing.

Titanium wire rope comes in several grades with grade two being 99% pure. It is easily formable and weldable. Titanium wire rope is commonly used in chemical processing and marine hardware.

For wire rope to perform properly, it needs to have proper care. Wire rope is an essential tool necessary to perform a wire range of lifting and moving jobs. It is important that it be handled, treated, installed, stored, and treated correctly to prolong its life and perform to the highest standards.

Seizing should be completed on both ends of the wire rope, which will protect it from loosening. If this is done improperly, the wire rope can become distorted. Wire rope that is properly seized evenly distributes the load.

Wire rope is stored on reels or coils and has to be carefully handled when it is being removed. To ensure excellent performance, the wire rope should not be dropped during removal. If the reel or coil is dropped or damaged, it can make handling the wire rope difficult and cumbersome. As the wire rope is removed from the reel, check to see that the reel is rotating as the wire is removed.

Wire rope is depended on for heavy lifting and is trusted to keep a load and people safe. As with all heavy duty equipment, wire rope must have a regular inspection schedule and be visually assessed during use.

Broken Strands – An easy way to check for broken strands is to run a cloth over the length of the wire. Broken strands that are found in critical areas, such as parts that pass through pulleys or sections that are regularly flexed, rubbed, or constantly worked must be replaced and repaired.

Internal wear – This can be tested by flexing the wire rope, which indicates if the interior has deteriorated, experienced fatigue, or become distorted.

For wire rope to perform at the highest level, it has to be stored in a well ventilated environment that is dry, covered, and not in contact with the floor. The avoidance of high moisture or damp conditions is an absolute necessity. While the wire rope is in storage, it should be moved regularly to keep the lubricant from wearing off.

Though lubricant is applied during the manufacturing of wire rope, it wears off during use. Lubrication is the key to the performance of wire rope because it helps prevent abrasion as the wires rub against one another. Relubrication should be applied after the original lubricant has worn off.

Wire rope is a tool and must be cleaned regularly as with any form of machinery. This can be accomplished with different types of petroleum solvents and a wire brush. Mechanical methods of cleaning can include compressed air or a steam cleaner. Once the cleaning process is completed, the wire rope should be lubricated for protection.

There are several substances that can harm a wire rope. They include salt water, brine, acid, various gasses, and humidity. To avoid the intrusion of these negative effects, when a job is completed and the wire rope is to be stored, it should be cleaned, lubricated, and placed in proper storage.

When wire rope is being removed from a spool or being spooled, the operation must be performed smoothly with the spool rotating at a constant speed and rhythm. This will help prevent kinking or binding.

When a wire rope shows a reduction in diameter, has broken wires, kinks, nodes, flattened surfaces, out of place outer wires, damage from heat exposure, corrosion damage, or the formation of unexpected loops, it should be removed and replaced or be repaired.

Wire rope is regulated by the Occupational Safety and Health Administration (OSHA) as part of the regulations for cranes and derricks in construction as part of 29 CFR 1926.1413, which went into effect on November 8, 2010.

The inspection of wire ropes is on three levels: shift, monthly, and annually. Shift and monthly inspections can be completed by an approved operator, while annual inspection must be completed by certified personnel.

As with the shift and monthly inspections, the annual inspection follows the guidelines for the shift inspection. This inspection must be completed by certified personnel. The entire surface of the wire rope has to be inspected, with attention to:

Annual inspections can be excused if it is not possible due to the wire ropes setup or configuration or the location of the work site. It must be completed within six months. If any deficiencies are found, the wire rope must be repaired or removed. For some deficiencies, it is possible to keep the wire rope in use but have them regularly monitored.

Wire rope is a form of metal tool that is constructed of multiple strands of wire that are twisted and braided together to form a spiral design or helix.

To further enhance the strength of wire rope, they are grouped and wound together to produce cables, which adds to their usefulness as a means of support, ability to lift, and give structural stability.

The types of wire rope are determined by the number of wires in each strand and how many are in the rope, which is defined by a two number system with the first number being the number of wires and the second being the number of wires in each strand.

Usha Martin’s global design centre in Italy develops wire ropes that exceed customer’s expectations and provide customers the benefits of technical developments in wire rope industry. Besides rope design and testing, the centre is actively engaged in providing technical assistance in the form of evaluating customer concept design of new equipment, conducting training for customers about rope properties, and managing special tests required by customers.

Wire rope consists of several strands of metal wire laid (twisted) into a helix. The term "cable" is often used interchangeably with "wire rope", but narrower senses exist in which "wire rope" refers to diameter larger than 3/8 inch (9.52 mm), whereas sizes smaller than this are designated cable or cords.wrought iron wires were used, but today steel is the main material used for wire ropes.

Historically wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure, flaws in the wires making up a steel cable are less critical as the other wires easily take up the load. Friction between the individual wires and strands, as a consequence of their twist, further compensates for any flaws.

Wire ropes were developed starting with mining hoist applications in the 1830s. Wire ropes are used dynamically for lifting and hoisting in cranes and elevators, and for transmission of mechanical power. Wire rope is also used to transmit force in mechanisms, such as a Bowden cable or the control surfaces of an airplane connected to levers and pedals in the cockpit. Only aircraft cables have WSC (wire strand core). Also, aircraft cables are available in smaller diameters than wire rope. For example, aircraft cables are available in 3/64 in. diameter while most wire ropes begin at a 1/4 in. diameter.suspension bridges or as guy wires to support towers. An aerial tramway relies on wire rope to support and move cargo overhead.

Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany.chains, such as had been used before.

Wilhelm Albert"s first ropes consisted of three strands consisting of four wires each. In 1840, Scotsman Robert Stirling Newall improved the process further.John A. Roebling, starting in 1841 suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope. Ever with an ear to technology developments in mining and railroading, Josiah White and Erskine Hazard, principal ownersLehigh Coal & Navigation Company (LC&N Co.) — as they had with the first blast furnaces in the Lehigh Valley — built a Wire Rope factory in Mauch Chunk,Pennsylvania in 1848, which provided lift cables for the Ashley Planes project, then the back track planes of the Summit Hill & Mauch Chunk Railroad, improving its attractiveness as a premier tourism destination, and vastly improving the throughput of the coal capacity since return of cars dropped from nearly four hours to less than 20 minutes. The decades were witness to a burgeoning increase in deep shaft mining in both Europe and North America as surface mineral deposits were exhausted and miner had to chase layers along inclined layers. The era was early in railroad development and steam engines having sufficient tractive effort to climb steep slopes were in the future, so incline plane railways were common, and the mining tunnels along inclined shafts between coal layers were just a which came first variant, but where steam engines could not go. This pushed development of cable hoists rapidly in the United States as surface deposits in the Anthracite Coal Region north and south dove deeper every year, and even the rich deposits in the Panther Creek Valley required LC&N Co. to drive their first shafts into lower slopes beginning Lansford and its Schuylkill County twin-town Coaldale.

The German engineering firm of Adolf Bleichert & Co. was founded in 1874 and began to build bicable aerial tramways for mining in the Ruhr Valley. With important patents, and dozens of working systems in Europe, Bleichert dominated the global industry, later licensing its designs and manufacturing techniques to Trenton Iron Works, New Jersey, USA which built systems across America. Adolf Bleichert & Co. went on to build hundreds of aerial tramways around the world: from Alaska to Argentina, Australia and Spitsbergen. The Bleichert company also built hundreds of aerial tramways for both the Imperial German Army and the Wehrmacht.

In the last half of the 19th century, wire rope systems were used as a means of transmitting mechanical powercable cars. Wire rope systems cost one-tenth as much and had lower friction losses than line shafts. Because of these advantages, wire rope systems were used to transmit power for a distance of a few miles or kilometers.

Steel wires for wire ropes are normally made of non-alloy carbon steel with a carbon content of 0.4 to 0.95%. The very high strength of the rope wires enables wire ropes to support large tensile forces and to run over sheaves with relatively small diameters.

In the mostly used parallel lay strands, the lay length of all the wire layers is equal and the wires of any two superimposed layers are parallel, resulting in linear contact. The wire of the outer layer is supported by two wires of the inner layer. These wires are neighbours along the whole length of the strand. Parallel lay strands are made in one operation. The endurance of wire ropes with this kind of strand is always much greater than of those (seldom used) with cross lay strands. Parallel lay strands with two wire layers have the construction Filler, Seale or Warrington.

In principle, spiral ropes are round strands as they have an assembly of layers of wires laid helically over a centre with at least one layer of wires being laid in the opposite direction to that of the outer layer. Spiral ropes can be dimensioned in such a way that they are non-rotating which means that under tension the rope torque is nearly zero.

The open spiral rope consists only of round wires. The half-locked coil rope and the full-locked coil rope always have a centre made of round wires. The locked coil ropes have one or more outer layers of profile wires. They have the advantage that their construction prevents the penetration of dirt and water to a greater extent and it also protects them from loss of lubricant. In addition, they have one further very important advantage as the ends of a broken outer wire cannot leave the rope if it has the proper dimensions.

Stranded ropes are an assembly of several strands laid helically in one or more layers around a core. This core can be one of three types. The first is a fiber core, made up of synthetic material or natural fibers like Sysal. Synthetic fibers are stronger and more uniform but can"t absorb much lubricant. Natural fibers can absorb up to 15% of their weight in lubricant and so protect the inner wires much better from corrosion than synthetic fibers do. Fiber cores are the most flexible and elastic, but have the downside of getting crushed easily. The second type, wire strand core, is made up of one additional strand of wire, and is typically used for suspension. The third type is independent wire rope core (IWRC), which is the most durable in all types of environments.ordinary lay rope if the lay direction of the wires in the outer strands is in the opposite direction to the lay of the outer strands themselves. If both the wires in the outer strands and the outer strands themselves have the same lay direction, the rope is called a lang lay rope (formerly Albert’s lay or Lang’s lay). Regular lay means the individual wires were wrapped around the centers in one direction and the strands were wrapped around the core in the opposite direction.

Multi-strand ropes are all more or less resistant to rotation and have at least two layers of strands laid helically around a centre. The direction of the outer strands is opposite to that of the underlying strand layers. Ropes with three strand layers can be nearly non-rotating. Ropes with two strand layers are mostly only low-rotating.

Stationary ropes, stay ropes (spiral ropes, mostly full-locked) have to carry tensile forces and are therefore mainly loaded by static and fluctuating tensile stresses. Ropes used for suspension are often called cables.

Track ropes (full locked ropes) have to act as rails for the rollers of cabins or other loads in aerial ropeways and cable cranes. In contrast to running ropes, track ropes do not take on the curvature of the rollers. Under the roller force, a so-called free bending radius of the rope occurs. This radius increases (and the bending stresses decrease) with the tensile force and decreases with the roller force.

Wire rope slings (stranded ropes) are used to harness various kinds of goods. These slings are stressed by the tensile forces but first of all by bending stresses when bent over the more or less sharp edges of the goods.

There are technical regulations for the rope drives of cranes, elevators, rope ways and mining installations not exceeding a given tensile force and not falling short of a given diameter ratio D/d of sheave and rope diameters. A general dimensioning method of rope drives (and used besides the technical regulations) calculate the five limits

Donandt force (yielding tensile force for a given bending diameter ratio D/d) - strict limit. The nominal rope tensile force S must be smaller than the Donandt force SD1.

Rope safety factor = minimum breaking force Fmin / nominal rope tensile force S. (ability to resist extreme impact forces) - Fmin/S ≥ 2,5 for simple lifting appliance

Discarding number of wire breaks (detection to need rope replacement) Minimum number of wire breaks on a reference rope length of 30d should be BA30 ≥ 8 for lifting appliance

Optimal rope diameter with the max. rope endurance for a given sheave diameter D and tensile rope force S - For economic reasons the rope diameter should be near to but smaller than the optimal rope diameter d ≤ dopt.

The wire ropes are stressed by fluctuating forces, by wear, by corrosion and in seldom cases by extreme forces. The rope life is finite and the safety is only ensured by inspection for the detection of wire breaks on a reference rope length, of cross-section loss, as well as other failures so that the wire rope can be replaced before a dangerous situation occurs. Installations should be designed to facilitate the inspection of the wire ropes.

Lifting installations for passenger transportation require that a combination of several methods should be used to prevent a car from plunging downwards. Elevators must have redundant bearing ropes and a safety gear. Ropeways and mine hoistings must be permanently supervised by a responsible manager and the rope must be inspected by a magnetic method capable of detecting inner wire breaks.

The end of a wire rope tends to fray readily, and cannot be easily connected to plant and equipment. There are different ways of securing the ends of wire ropes to prevent fraying. The most common and useful type of end fitting for a wire rope is to turn the end back to form a loop. The loose end is then fixed back on the wire rope. Termination efficiencies vary from about 70% for a Flemish eye alone; to nearly 90% for a Flemish eye and splice; to 100% for potted ends and swagings.

When the wire rope is terminated with a loop, there is a risk that it will bend too tightly, especially when the loop is connected to a device that concentrates the load on a relatively small area. A thimble can be installed inside the loop to preserve the natural shape of the loop, and protect the cable from pinching and abrading on the inside of the loop. The use of thimbles in loops is industry best practice. The thimble prevents the load from coming into direct contact with the wires.

A wire rope clamp, also called a clip, is used to fix the loose end of the loop back to the wire rope. It usually consists of a U-shaped bolt, a forged saddle, and two nuts. The two layers of wire rope are placed in the U-bolt. The saddle is then fitted over the ropes on to the bolt (the saddle includes two holes to fit to the u-bolt). The nuts secure the arrangement in place. Three or more clamps are usually used to terminate a wire rope. As many as eight may be needed for a 2 in (50.8 mm) diameter rope.

There is an old adage; be sure not to "saddle a dead horse." This means that when installing clamps, the saddle portion of the clamp assembly is placed on the load-bearing or "live" side, not on the non-load-bearing or "dead" side of the cable. According to the US Navy Manual S9086-UU-STM-010, Chapter 613R3, Wire and Fiber rope and Rigging, "This is to protect the live or stress-bearing end of the rope against crushing and abuse. The flat bearing seat and extended prongs of the body (saddle) are designed to protect the rope and are always placed against the live end."

An eye splice may be used to terminate the loose end of a wire rope when forming a loop. The strands of the end of a wire rope are unwound a certain distance, and plaited back into the wire rope, forming the loop, or an eye, called an eye splice. When this type of rope splice is used specifically on wire rope, it is called a "Molly Hogan", and, by some, a "Dutch" eye instead of a "Flemish" eye.

Swaging is a method of wire rope termination that refers to the installation technique. The purpose of swaging wire rope fittings is to connect two wire rope ends together, or to otherwise terminate one end of wire rope to something else. A mechanical or hydraulic swager is used to compress and deform the fitting, creating a permanent connection. There are many types of swaged fittings. Threaded Studs, Ferrules, Sockets, and Sleeves are a few examples.

A wedge socket termination is useful when the fitting needs to be replaced frequently. For example, if the end of a wire rope is in a high-wear region, the rope may be periodically trimmed, requiring the termination hardware to be removed and reapplied. An example of this is on the ends of the drag ropes on a dragline. The end loop of the wire rope enters a tapered opening in the socket, wrapped around a separate component called the wedge. The arrangement is knocked in place, and load gradually eased onto the rope. As the load increases on the wire rope, the wedge become more secure, gripping the rope tighter.

Poured sockets are used to make a high strength, permanent termination; they are created by inserting the wire rope into the narrow end of a conical cavity which is oriented in-line with the intended direction of strain. The individual wires are splayed out inside the cone or "capel", and the cone is then filled with molten lead-antimony-tin (Pb80Sb15Sn5) solder or "white metal capping",zincpolyester resin compound.
