u bolt clips wire rope supplier

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.

Wire rope clips are quite small in relation to an entire wire rope setup, but this small hardware piece plays a key role in security and durability. The role of the wire rope clip is to join the end of the wire rope securely to create a loop. This may be used for overhead lifting, along with other numerous purposes, like:

There are different design styles for wire rope clips, but all clips work similarly. There is a rounded opening that fits around the wire rope. The clip is closed by two screws with bolts, causing the rounded opening to tighten around the wire rope, holding it firmly in place.

Since this hardware is used in applications that involve heavy equipment, which can be dangerous, wire rope clips need to be used correctly. Here are the things to keep in mind for a safe wire rope installation:

There are two types of wire rope clip designs: U-bolt or double saddle. It should be noted that only drop forged U-bold wire rope clips are permitted for overhead lifting, double saddle clips are not.

A U-bolt clip is made with a U-shaped bolt, along with a metal base or saddle piece that fits around the wire rope. This is held in place with two nuts that screw on the bottom of the clip.

A double saddle wire rope clip is made from two separate bolts that are held in place by bolts on either side. This different design is somewhat easier to use, as there is no top or bottom. However, they have a lower load capability, which is why they aren’t recommended for rigging.

There are also several types of metals used to make wire rope clips. As mentioned, drop forged clips are the only type that is permitted for overhead lifting. This is made from molten steel that is shaped into place with a ram hammer, making it quite durable. This type of clip is also hot galvanized for additional protection and corrosion resistance.

Wire rope clips may also be purchased in stainless steel and malleable electro-galvanized options. While stainless steel is a very strong metal, it is considered soft and may bend under heavy-duty applications – which is why it shouldn’t be used for overhead lifting. Malleable wire rope clips may even fracture under heavy loads and are best used for light-duty applications like fencing.

The way that a wire rope clip is installed is extremely important, as the placement and angle can interfere with its strength and hold. Before installing, the wire ropes should be inspected and the clips should be checked for several things, including:

Remember to inspect the wire rope before adding the clips on as well. Without proper care or handling, wires in the rope may snap or corrode. Even though the wire rope clips may be in good shape, they won’t hold well if the wire rope is damaged.

Be sure to double-check all safety factor calculations as well. When clips are used to create a sling for overhead lifting, it diminishes up to 75% of the wire rope’s original working load limit. Keep this in mind!

The next step in wire rope clip installation is placement and securement. First, you will measure out the end length of the wire rope that will need to be secured with the clips. A heavy-duty thimble may be added inside of the loop for added support.

Next, undo the clips so they are separated into two parts and fit the U-bolt around the two wire ropes. Then, tighten both of the bolts evenly until they are securely fastened, holding the ropes firmly in place.

Multiple clips should be used for added security with space measuring between 1.5 to 3 times the length of the clip apart. All wire rope clips must be facing the same direction and should be evenly spaced apart.

The majority of issues come with not following the proper requirements for wire clip installation. Failing to follow the rules for spacing, placement, or using the wrong type of clip can be quite dangerous, causing the rope to slip.

Another common issue is not torquing the bolts correctly. This includes both under-torquing and over-torquing. If the bolts are too tight, they will actually wear down the threads of the wire rope beneath. Be sure to follow the manufacturer’s directions on the clips for proper torquing techniques.

Finally, wire rope clips will need to be retightened or cycled out. No bolts will stay perfectly in place for a prolonged period of time, especially if there is a high level of friction. Clips should also be relocated and cycled out after multiple uses.

Ultimately, the quality of your wire rope clips should be a top priority, as this will impact how well the clips work and how long they last.

Wire rope clips are widely used for making end terminations. Clips are available in two basic designs; the U-Bolt and fist grip. The efficiency of both types is the same.

When using U-Bolt clips, extreme care must be exercised to make certain that they are attached correctly; Incorrect installation can reduce the working load limit by 40%. Below are general guidelines for installing wire rope clips.

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.

Step 1. Turn back a specified amount of rope from the thimble or loop. The first clip must be placed one bridge width from the turned back rope tailor dead end of the rope, Apply U-Bolt over dead end of wire rope – live end rests in the saddle (Never saddle a dead horse!) Tighten nuts evenly, alternate from one nut to the other until reaching the recommended torque.

Step 2. When more than two clips are required, apply the second clip as near the loop or thimble as possible, tighten the nuts firmly but not yet to the specified torque.

Step 3. When three or more clips are required, space additional clips equally between the first two – take up rope slack – tighten nuts on each U-Bolt evenly, alternating from one nut to the other until reaching recommended torque.

Step 4. Apply the first load to test the assembly. This load should be of equal or greater – weight than loads expected in use. Next, check and retighten nuts to recommended torque.

In accordance with good rigging and maintenance practices, the wire rope end termination should be inspected periodically for wear, abuse, and general adequacy. 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.

Malleable clips are to be used for making eye termination assemblies only with the right regular lay wire rope and only for light-duty uses with small applied loads, such as handrails, fencing, guard rails, etc.
