Info Wire rope clips

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.

Instructions for use

Wire rope clips should be inspected before use to ensure that:

• All markings are legible;
• A wire rope clip with the correct dimensions has been selected;
• The nuts or any other locking system can not be disconnected unexpectedly due to vibration/external factors;
• The wire rope clip is free from nicks, gouges and cracks;
• Never modify, repair or reshape a wire rope clip by machining, welding, heating or bending as this may affect their quality.

The wire rope clip should be fitted to the wire rope as shown in below figures.

The saddle 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.

Make sure a sufficient length of rope tail in order to ensure the required amount of clips can be installed.

The first clip must be placed one saddle width from the plain end as shown in (figure 1). Tighten the nuts to the specified torque value.

The second clip must be placed directly behind 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 clips there after should be placed on the wire rope between the first and second clip in such a way that they are separated by at least 1 ½ times the clip-width with a maximum of 3 times the clip-width, according to (figure 3).

Apply light tension on the rope and tighten all nuts evenly.

The efficiency of a wire rope termination made with wire rope clips depends on the correct installation of the clips on the steel wire rope and on correct fitting and fastening of the clips. With inadequately fastened nuts or with an insufficient number of wire rope clips the rope end may slip through the clips during use.

The quality of installation of the clips on the ropes may be affected by various circumstances,
such as:

• The nut may be tight on the thread, yet not tight against the bridge;
• Affected thread by dirt, oil or corrosion my result in poor fastening of the nuts.

Heavy duty forged wire rope clips provide a more solid bearing surface compacted to cast iron clips.

Wire rope clips may not be used in for:

• Hoist ropes in mines;
• Rope drives for cranes in steel works and rolling mills;
• Permanent fastening of ropes in other rope drives;
• 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;
• Lifting

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.
