Holding the record for the top 3 heaviest lifts; theTaisun crane in China is the strongest crane that exists in the world today. With a working load limit of over 44 million pounds or 20,000 metric tons this crane is surely a modern marvel. The amount of wire rope required to operate Taisun is nearly 50,000 meters or just over 31 miles; allowing it to lift a maximum of 80 meters. While not everyone may need 31 miles of wire rope, or have a need to lift 44 million pounds, we have a wide variety of materials required to lift, push, pull, and move whatever is in your way.

The standard Wire Rope for the Steel fabricating industry is 6 x 19 EIP/IWRC. In short this means the wire rope is made up of 6 independent wires. Each of these 6 wires has 19 individual strands.

The illustration below shows the configuration of standard Wire Rope in Classification 6 x 19 IWRC / EIP. IWRC refers to the inner core strand, which is independent of the 6 outer strands.

Wire rope clips, sometimes referred to as u bolt clamps, u bolt clips, u clips, u clamps or cable clamps, are used to secure the loose end of a wire rope when forming an eye. Wire rope u clips have a u-bolt that is secured into a saddle by two nuts. Wire rope assemblies almost always require two, or more wire rope clamps to secure the wire rope properly. When using wire rope cable clamps to form an eye in a wire rope, the working load limit of the wire rope is reduced by about 20%.

Here at Tri-State Rigging Equipment we pride ourselves on providing only the highest quality wire rope clamps from only the most reputable manufacturers. We can provide you with any wire rope clip on the market so, if you are unable to find what you are looking for, or if you don’t know exactly what you need, call or email our sales team to speak with a rigging product specialist.

Wire rope cable clamps come in a variety of materials ranging from galvanized and zinc plated steel, to stainless steel. The two most important different types, however, are drop forged and malleable wire rope u bolt clips.

Drop forged wire rope clips are more heavy duty than malleable rope clips and can therefore be used for more heavy-duty rigging applications. In addition, they are galvanized with a heavy coating of zinc that resists the corrosion and abuse found in rugged work environments. Wire rope cable clamps of every type are not designed to be used in an overhead lift but drop forged wire rope u bolt clamps can be used to suspend an overhead load. This makes wire rope cable clamps ideal for use with:

Regarding the first question, if the load is being moved, wire rope clips are not to be used. If the load is being held in place, heavy-duty drop forged wire rope clips can be used. For the second question, if the load is near the ground, malleable wire rope clips may be used, as their lighter duty design is more than enough for the job. On the other hand, if the load is being suspended above the ground, heavier duty drop forged wire rope clamps must be used.

In the rigging and lifting industry there is a common saying that is used to remember the correct way to use wire rope u clips: “Never saddle a dead horse.” This means that the saddle of the u clamp should always be in contact with the live side of the wire rope rather than the dead side. The dead side of the wire rope is the side of the eye that has the cut end. The dead end is attached to the live end of the wire rope to form an eye and it is imperative that the saddle be on the live side of the wire rope.

Tri-State Rigging Equipment is a service provider and distributor for all wire rope cable clamps, and u bolt clips for rigging serving clients from coast to coast, Canada, Mexico and especially focused in the states of Missouri, Illinois, Indiana, Iowa, Kansas, Nebraska, Arkansas, Mississippi, Tennessee, Kentucky, South Carolina, Florida, and Oklahoma.

Wire rope clip is otherwise known as a wire rope clamp, wire cable clamp, wire clamp, wire clip, U-bolt, etc. It is widely used for making eye-loop connections or join two wire rope cable ends together. The traditional styles of wire rope clips usually have three components: a U-shaped bolt, a forged or cast iron saddle, and two nuts.

The wire rope clips are available in a range of sizes and finishes, while you can easily find the difference from the appearance, traditional wire clips with u bolt, saddle and nuts, fist grip, stamped cable clamp.

Cast and malleable wire rope clips can only be used under light duty loads applications with relatively light loads, such as handrails, fencing, guard rails, etc.

While the drop forged wire rope clip variety is recommended for important, critical or sustaining overhead loads, such as guy lines, support lines, scaffolding, etc. The drop forged wire rope clips can be used in critical suspending, guying, and tie-down applications for the die forging process make them strong and more durable and the heating and hammering steps make their structure to be consistent and conform to the shape of the forged item.

Simplex and duplex cable clamps are also known as single stamped wire clip and double stamped cable clip are composed of stamping plate, saddle, and bolts, feature an aesthetic design, used for outdoor light duty applications.

Wire rope clips are available in a variety of materials and finishes but basically three types of materials, carbon steel, cast, malleable iron, and stainless steel.

Carbon steel wire rope cable clamps are galvanized, or hot dipped galvanized, the galvanised metal wire clamp has an added zinc layer to prevent rusting and protect against scratching and the addition of carbon corresponds with an increase in the hardness and strength of wire rope cable clamps. G, but stainless steel wire rope clamps are the best choice for corrosion-resistant applications that can be used for saltwater environments.

Commonly wire rope clamp installation is very simple, there’s a well-known saying can help you remember how to attach wire rope clips, that reads “never saddle a dead horse.” Just follow the recommendation ways:

Keep three or more wire rope clips attached at the end of the wire rope dead end, space between each wire rope clip should be at least 6 times the wire rope diameter.

You can see the correct and incorrect ways of installation from the following pictures and find how many wire rope clips to use at one wire rope loop.

The saddle shall be placed on the live end of the wire rope, with the U-bolt on the dead-end side—Remember the well-known saying: “Never saddle a dead horse.” Use at least two or three wire rope clips to secure the ends properly to the length of the rope, and tighten nuts evenly one by one until reaching the recommended torque.

Wire ropes are one of the most critical pieces of rigging and lifting hardware. You can use wire ropes for lifting, rigging, and tying loads of virtually any size, shape, and type. To make the most out of wire ropes, however, you need a few additional rigging equipment, one of which includes wire rope clamps.

Also known as wire rope clips, riggers often use this nifty little piece of hardware at the end of the length of a wire rope. You can use a wire rope clamp to:Tie two wire ropes together using a lap splice.

In short, a cable clamp is what makes a wire rope one of the most versatile pieces of rigging hardware. As these clamps come in different shapes, sizes, and materials, you will need to choose one that perfectly fits your lifting and rigging application. But before we get down to that, first, you need to understand what is wire rope clamp, its types, and a few other things.

It is a simple mechanical device. A typical wire rope clip consists of a saddle, U-bolt, and two hex nuts. This simple device is suitable for less permanent rigging and lifting applications. You must never use wire rope clips to make industrial slings.

The ASME B30.9 Slings standard clearly states that riggers should not use mechanical wire rope terminations that require periodic adjustments to create slings. In other words, you need to be careful when using rope clamps. You can use a wire rope clip to create an end loop for a winching or crane cable. You can also use it to build perimeter cables or increase the length of a wire rope going through a D-shackle or eye bolt.

Based on their shape, there are two types of cable clamps, U-bolt and double saddle. They both have unique mechanical properties and hence applications.

These cable clamps consist of a U-bolt, two nuts, and a metal base called a saddle. The U-bold passes through the saddle, which you can tighten with the two nuts. They come in various sizes and types of materials, including stainless steel and galvanized steel. You can choose a U-bolt wire rope clamp depending on your rigging or lifting application.

Usually, there are three types of materials used for making rope clips. You can choose a material based on your application as each one comes with its unique strengths and weaknesses.

In this type of wire rope clip, the base or saddle is made from forged steel. The manufacturing process involves heating and hammering the clips into desired shapes. Riggers often use these cable clamps for critical and heavy-duty applications as they are very strong. You can see them in winch lines, crane cables, hoist lines, towing lines, scaffoldings, guy lines, and even tie-downs.

The base or saddle is made from cast iron. As cast iron lacks the metal properties of stainless steel, it is not that strong. So, the malleable galvanized wire rope clamps are not very strong. They can break under heavy usage. You will see them being used in small or light-duty applications like fencing, parameter cables, or guard rails.

Stainless steel wire rope clips are arguably the best ones. The base or saddle is made from high tensile strength stainless steel. They are durable and easy to use. You can find these cable clamps in temporary guard rails, flag posts, and other outdoor rigging applications.

Wire rope clamps are an essential part of the rigging hardware. You can’t do away with them. But you have to make sure to use the right ones to keep the load and the riggers safe. If a wire rope snaps because you used the wrong type of clip, it can lead to disastrous consequences.

As you can see, each wire rope clamp comes with unique properties. You need the instruction manual to understand when, where, and how to use the cable clamps. Make sure the clamps are accompanied by respective user manuals when making a purchase.

By now, you know that some cable clamps are more suited for outdoor environments, while others aren’t. As a result, carefully think about where you want to use the wire rope clips. For example, if it’s a heavy outdoor application, stainless steel wire rope clamps would be a great fit.

Lastly, it’s always better to get an expert on board when shopping for wire rope clips. Maybe you can hire an engineer or expert with considerable field experience to help you choose the right types of clamps. An expert will help you take every detail into account before making the purchase. Remember, if you choose the right cable clamps right off the bat, you’ll save considerable time and money down the line.

Wire rope clamps are one of the essential rigging hardware. They land wire ropes more flexibility, allowing you to handle a wide range of applications with ease and safety. These are some tips that will help you choose the appropriate clamp for your need.

In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3⁄8 in), with smaller gauges 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. While friction between the individual wires and strands causes wear over the life of the rope, it also helps to compensate for minor failures in the short run.

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 1.2 mm (3⁄64 in) diameter while most wire ropes begin at a 6.4 mm (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 1841suspension 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 miners had to chase layers along inclined layers. The era was early in railroad development and steam engines lacked sufficient tractive effort to climb steep slopes, so incline plane railways were common. 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 neighbors 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 sisal. Synthetic fibers are stronger and more uniform but cannot 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 (from Dutch langslag contrary to kruisslag,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.

Technical regulations apply to the design of rope drives for cranes, elevators, rope ways and mining installations. Factors that are considered in design include:

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.

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

The mnemonic "never saddle a dead horse" means that when installing clips, the saddle portion of the assembly is placed on the load-bearing or "live" side, not on the non-load-bearing or "dead" side of the cable. 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 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, then bent around so that the end of the unwrapped length forms an eye. The unwrapped strands are then plaited back into the wire rope, forming the loop, or an eye, called an eye splice.

A Flemish eye, or Dutch Splice, involves unwrapping three strands (the strands need to be next to each other, not alternates) of the wire and keeping them off to one side. The remaining strands are bent around, until the end of the wire meets the "V" where the unwrapping finished, to form the eye. The strands kept to one side are now re-wrapped by wrapping from the end of the wire back to the "V" of the eye. These strands are effectively rewrapped along the wire in the opposite direction to their original lay. 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. Threaded studs, ferrules, sockets, and sleeves are examples of different swaged terminations.

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.
