wire rope clips how to use free sample

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.

Sometimes called a u-bolt,u-bolt clip or cable clip, they can be used to join two wire rope ends together, make an eye for a pulling application, or to secure the loose end of a wire rope after a wedge socket (or other appropriate device) has been used to terminate a crane’s hook.

ASME B30.9 states that wire rope clips shall not be used to fabricate wire rope slings, except where the application of slings prevents the use of prefabricated slings.

ASME B30.9 states wire rope clips shall be drop-forged steel of single saddle (u-bolt) or double saddle clip. Malleable cast iron clips shall not be used.

Wire rope clips diminish the working load limit of the wire rope to generally about 70-75% of its original strength. There are better and more efficient ways to fabricate slings for overhead lifting.

For situations where use of wire rope clips are approved, it’s important to remember the proper way to install the clips. Incorrect installation can reduce the working load limit by 40% or more. The easiest thing is to remember, “never saddle a dead horse.”

To comply with manufacturer’s specification the correct number of clips must be installed correctly andtightened to the correct torque using a torque wrench. The correct installation technique is shown below.

The bridge of the wire rope clip should always be placed on the load bearing part of the rope. The U-bolt ofthe clip should be placed on the rope tail, also known as the “dead end” of the rope.

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 nuts to the specified torque.

The second clip must be placed immediately against the thimble but nevertheless in such a position that thecorrect tightening of the clip does not damage the outer wires of the wire rope (figure 2). Tighten the nutsfirmly but not yet to the specified torque.

During assembly and before the rope is taken into service, the nutsmust be tightenedonce again to theprescribed torque. After the load is applied for the first time, the torque value must be checked again andcorrected if necessary. Periodically re-tightening of the nuts must be done at 10.000 cycles (heavy usage),20.000 e.g. every 3 months, 6 months, annually.

In addition, for clips to work properly and gain their design efficiency, the proper number of clips is required and the nuts must be torqued as prescribed by the manufacturer. For more information on proper installation, check out this video from the Crosby Group.

Wire rope is an extremely versatile mechanical device that can be used to help support and move an object or load. Whether for use on cranes or for other lifting applications, it’s important to have a solid understanding of the rigging components that are being used to attach to and lift a load.

As a rigger or end-user of wire rope, it’s necessary to understand the types of wire rope end termination, or treatments that can be used at the ends of a length of wire rope—one of the most common being wire rope clips.

Wire rope clips can be used to form a load bearing eye at the end of a cable or wire rope, or to connect two cables together with a lap splice. Wire rope clips are popular because they can be installed in the field and provide 80-90% efficiency of the rope breaking strength, depending on the diameter of the wire rope.

As a general guideline, they are NOT to be used for making slings, as ASME B30.9 Slingsstandard states: “Mechanical wire rope terminations requiring periodic adjustment to maintain efficiency shall not be used to fabricate slings.”

There are two main types of wire rope clips—U-Bolt and double saddle clips. U-Bolt wire rope clips are the most common and may be made of forged or malleable metal.

This type of wire rope clip is essentially a U-bolt, two nuts, and a metal base (saddle) that can be made from forged steel or cast iron. Careful consideration and attention must be given to the way U-bolt type wire rope clips are installed.

The base of the wire rope clip is made from forged steel. Forged clips are heated and hammered into the desired shape—resulting in a consistent grain structure in the steel. Forged wire rope clips are used for critical, heavy-duty, overhead loads such as winch lines, crane hoist lines, support lines, guy lines, towing lines, tie downs, scaffolds, etc.

Malleable wire rope clips are used for making eye termination assemblies only with right regular lay wire rope and only for light duty uses with small applied loads, such as hand rails, fencing, guard rails, etc. The base of the wire rope clips is made from malleable cast iron, which may fracture under heavy use and does not have the desirable metal properties of steel, or the beneficial grain structure that a forged base has.

Unfortunately, it is not uncommon to see a wire rope clip applied incorrectly. Some of the most common mistakes include:Not torquing to the manufacturer’s expectations

Wire rope clips require the use of a torque wrench in order to function properly. Torquing the nuts on the clips too much or too little can cause the clip to fail. If the clip is over-torqued, it could damage the threads of the wire rope. If the clip is under-torqued, the holding power of the clip is diminished and the wire rope could slip through.

There are a minimum number of clips required for use related to the wire rope diameter. Using less than the number of specified clips could result in decreased efficiency and possible failure.

Depending on the number and size of the wire rope clips, there is a proportional amount of space required between the placement on each clip on the rope.

There are two sides of a U-Bolt style wire rope clip: the saddle and the U-Bolt. When securing a wire rope eye, it is important to place the clip on the correct end of the rope.

A saying commonly used in rigging to help remember this is: “Never saddle a dead horse!” In other words, never put the saddle on the dead end of the rope.

The turnback is the portion of the wire rope eye that runs from the end of the bearing eye to the live end. Having less than the suggested amount of turnback will decrease the efficiency of the wire rope eye and could lead to failure.

It is important to be sure you are using the correct wire rope clip—forged or malleable wire rope clips—for the application. Malleable clips can only be used for non-critical uses, such as tension rope to form a perimeter around a parking lot.

If the use is critical—an application where, if there is a failure, you have potential injury or loss of life or damage to property—a forged clip must be used.

The clip size used—whether it be 1/8”, 3”, or otherwise—must match the diameter size of the wire rope. If it doesn’t, the wire rope could slip out of the clip.

After installing clips, it is necessary to regularly cycle the rope and retighten the clips. Monitoring the torque on the nuts is important, as they will loosen over repeated use.

Basic steps for installing a wire rope clip include:First, wrap the wire rope around the thimble or to form the eye, and turn back the correct amount of rope—as specified by the manufacturer.

Apply the first wire rope clip at the end of the dead end, with one base width of space. Use a torque wrench to tighten the nuts on the wire rope clip.

When applying the second clip (if required), place it as close to the eye loop or thimble as possible. Again, be sure to properly tighten the nuts of the clip with a torque wrench.

Wire rope clips are a common and necessary piece of rigging hardware when it comes to using wire rope and forming end terminations. They are used to form a wire rope eye or to connect two cables together. It’s important to understand how to correctly install a wire rope clip, as incorrect installation leads to decreased efficiency in the wire rope assembly.

There’s only one right way to install cable clips to get maximum efficiency (up to 85%) out of a prepared loop or thimble-eye termination – otherwise, the termination can be severely reduced in capacity.

You also need to know the number of clips required, the amount of rope to turn back from the thimble, and the torque needed to tighten the nuts. There are tables that detail all of this information.

All three clips must be installed with the saddle part on the live end of the rope. This allows the live end to rest in the saddle, and to not be crushed by the U-shaped part of the clip.

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:

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.

These claps consist of two saddles with one leg each and two nuts. As the saddles are mirrored, they can fit into each other without a bolt. This unique design also means you can use these in either direction, which makes them more user-friendly.

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.

The first step in choosing cable clamps is to buy them from a trusted and reputed rigging hardware manufacturer. The last thing you want is to use a defective or poor-quality clip. This will compromise the safety of your load and your crew.

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.

Taking into account how large and heavy the load is also equally important. Heavier loads will require strong cable clamps that won’t break under stress. Also, you shouldn’t use clips for any permanent rigging or lifting applications. They are suited only for temporary load applications.

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.

Wire rope thimbles also known as cable thimbles, are used for making reinforce loop(eyelet) with grips, clips or clamps by preventing fraying caused by friction at the bearing anchor point to protect and extend the service life of the wire rope or sling. They are just one of the many types of wire rope fittings (ferrules, wire rope clips, terminals, etc.).

Wire rope thimbles are available in a variety of strengths and materials(carbon steel and stainless steel, see our post on Surface Finish: 4 Common Types You Should Know) but mainly they come in two different duty grades.

If you use it in high moisture or corrosive environments, recommend our stainless steel wire rope thimbles which can offer resistance to corrosion on the surface, particularly in marine applications.

Simply wrap the end of the wire rope around the outer groove of the thimble, lace the dead end of the wire rope past the U-bolt of the wire rope grips or a wire rope ferrule crimp to hold onto the bearing anchor point at the end of the thimble to prevent fraying caused by friction.

Once in place, put another wire rope clip as near the loop you just wrapped over the thimble. Turn nuts firmly but do not yet tighten to the proper torque, we recommend using a crimping/swaging tool to compress the ferrule firmly onto the rope to hold your thimble loop securely.

Alternatively, you can use a wire rope ferrule crimp to secure your thimble in place. this method is quick and easy to install. For further information on installation using a wire rope ferrule please – click here

Wire rope thimbles are used in conjunction with cable and rope to protect the eyes and will allow for smooth rope guiding around natural curves. So that the most important thing is to make sure the thimble eye securely fastened. Here are some tips for correctly using wire rope thimble:

Make sure that the cable thimbles size properly and securely fastened in the eye of the loop, not too loose or too tighten, so they can create an extra layer of support to connect with other properly sized rigging fittings.

While you are using a vinyl coated cable, you should multiply the actual size of the cable, usually use a larger size thimble than normal, for the actual diameter is the thickness of the vinyl coating plus the inside wire rope diameter. For example, if you are using a 5/16″ vinyl coated cable that is coated to 3/8″ diameter, you’d want to use a 3/8″ wire rope thimble.
