wire rope clips how to use factory

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.

Rigging supplies exist to make lifting easier and safer, but this cannot be the case if supplies are used improperly. Mishandling Rigging supplies could, in certain cases, mean the difference between life and death. If used correctly, it can also save a substantial amount of time and money. Make sure to read all information and literature that is provided with the supplies you buy.

All products come with instructions about unpacking, installation, and use. Reading and being familiar with the language in these books is vital. Slight mistakes in installation can have substantial ramifications.

For instance, Wire Rope Clips (U-bolt clamps) are used to clamp the end of a piece of wire rope after being looped back to create an eye. Proper attachment requires knowledge of how many Wire Rope Clips are needed per size of Wire Rope. Please see www.bilcogroup.com for this information.

It is important to use the saddle of the clip on the live end of the eye. The U-bolt should always go around the dead end part of the eye. The saddle will always remain on the live end. Do not reverse every other clamp. This is a misconception. It is incorrect to put the U-bolt of any Wire Rope Clip onto the live end of a rope. For further instructions for setting up wire rope clips, please contact the selling company or refer to the instruction booklet.

While these clips are not designed to be used in an overhead lifting situation (swage sleeves should be used instead), wire rope clips are heavy-duty wire rope clips that used for sustaining overhead loads. Examples include guy lines, support lines, scaffolding, etc.

U.S. Cargo Control offers two types of clips: standard (or U-Bolt) and fist-grip (or "double saddle"). Our line includes high-quality clips that work for any situation, including:

Install the first clip at the dead end side of the rope. The "U" side of the clip must always cover the dead end of the rope, and the "saddle" side of the clip on the live end of the rope. Place the nuts of the clip and tighten them using a torque wrench.

Next, apply the second clip and place it as close to the eye loop as possible. Same application for the clip. Tighten the nuts of the clip with a wrench. (If you"re planning on using more than two clips, do not tighten the nuts on the clip.)

Place more clips on the rope if you need more than two on the wire rope. Be sure to space them evenly between the end clips. Finally, tighten the end clips and apply tension to reach the recommended torque for the wire rope.

Wire rope is commonly used to lift heavy loads. It consists of braided strands of metal, such as steel. When compared to traditional rope, wire rope is stronger and able to support heavier loads.

When using wire rope, however, you’ll need to secure it to an appropriate anchor point. Fortunately, there are wire rope clips available for this purpose

Wire rope clips are load-bearing components that are designed for use with wire rope. To lift an object with wire rope, you’ll typically need to use a load-bearing component. Wire rope clips offer an effective solution. You can mount them to the top of an object, after which you can secure the wire rope to it. The wire rope clip will hold the wire rope while allowing you to lift the object to which it’s mounted.

How do wire rope clips work exactly? There are different types of wire rope clips, each of which works in a different way. One of the most common types, though, is U-bolt.

U-bolt wire rope clips consist of a U-bolt, a saddle and a pair of nuts. You can see an example of a U-bolt wire rope clip in the photo above. The U-bolt itself is the semi-circular orange piece. The saddle, conversely, is the set of pronged metal pieces on the sides of the U-bolt. Finally, the nuts are the threaded fasteners attached to the bottom of the U-bolt.

To use a U-bolt wire rope clip, you’ll need to remove the nuts from the U-bolt. You can then insert the U-bolt wire rope clip onto the top of the object that you intend to lift. Once positioned, you’ll need to reattach the nuts. The nuts will hold the U-bolt wire rope clip to the object. You can then lift the object by placing wire rope through the center of the U-bolt.

There are also dual-saddle wire rope clips. As the name suggests, dual-saddle wire rope clips have two saddles rather than a single saddle. Each of the two saddles has a built-in bolt, which is attached to a nut. You can remove the nuts to place a dual-saddle wire rope clip on an object.

Wire rope clips are anchor points for wire rope There are U-bolt wire rope clips and dual-saddle wire rope clips. They work by creating a secure load-bearing point on objects so that equipment can lift the object with wire rope.

Dawson Clips, all sizes 1/4" and larger, meet the performance requirements of Federal Specification FF-C-450 TYPE 1 CLASS 1, except for those provisions required of the contractor.

Wire rope clips are used on wire rope eye-loop connections or complete loops, end-to-end connections where socketing or splicing is not feasible or when a temporary joint is required.

Dawson offers a wide range of wire rope clips in specifically standardized models such as EN 13411-5 and DIN wire rope clips. also offers a wide range of other wire rope clips

Dawson wire rope clips are drop forged and have a bridge with grooves to tighten the wire rope properly in the clip; the DIN wire rope clips have a malleable base, without grooves.

The wire rope clip should be fitted to the wire rope as shown in below figures. The bridge of the wire rope clip should always be placed on the load bearing part of the rope. The U-bolt of the clip should be placed on the rope tail, also known as the dead end of the rope. Turn back enough wire rope length so that the required minimum number of clips can be installed according to the instructions below.

The first clip must be placed one bridge width from the turned-back rope tail or dead end of the rope, according to figure 1. Tighten the nuts to the specified torque.

The second clip must be placed immediately against the thimble. Take care that the correct tightening of the clip does not damage the outer wires of the wire rope (figure 2). Tighten the nuts firmly but not yet to the specified torque.

The following clips should be placed on the wire rope between the first and second clip in such a way that they are separated by at least 1½ times the clip-width with a maximum of 3 times the clip-width, according to figure 3.

After assembly and before the rope is taken into service, the nuts must be tightened further to the prescribed torque. After the load has been applied to the assembly for the first time, the torque value must be checked and corrected if necessary. Re-tightening of the nuts must be done at 10.000 cycles (heavy usage), 20.000 cycles (moderate usage) or 50.000 cycles (light usage). If cycles are unknown, a competent person could fix a time period, e.g. every 3 months, 6 months, annually.

The efficiency of a wire rope termination made with wire rope clips depends on the correct placement of the clips on the rope and on correct fitting and tightening of the clips. With inadequately tightened nuts or with an insufficient number of wire rope clips the rope end may slide through the clips during use.

Suitable applications of wire rope clips to EN 13411-5 standards include suspending static loads and single use lifting operations which have been assessed by a competent person taking into account appropriate safety factors.

• rope terminations for load suspension devices in the operation of lifting appliances, except in the case of lifting tackles where these are produced for a special application and used only once.

Wire rope clips must be regularly inspected in accordance with the safety standards given in the country of use. This is required because the products in use may be affected by wear, misuse, overloading etc. Which may lead to deformation and alteration of the material structure. Inspection should take place at least every six months and more frequently when the products are used in severe operating conditions.

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.

The ends of individual strands of this eye splice used aboard a cargo ship are served with natural fiber cord after splicing to help protect seamens" hands when handling.

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.
