Wire Rope Clips Installation Guide
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.
First, wire rope clips should be inspected before use to ensure that:
• all markings are legible;
• the wire rope clip is free from nicks, gouges and cracks;
• a wire rope clip with the correct dimension has been selected;
• never repair or reshape a wire rope clip by welding, heating or bending as this may affect the performance.
And then, The following is based on the use of proper size U-Bolt clips on new rope.
Step 1. Turn back specified amount of rope from thimble or loop. The first clip must be placed one bridge width from the turned back rope tail or dead end of the rope, Apply U-Bolt over dead end of wire rope – live end rests in 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 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 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.
Also, the tightening and retightening of the nuts must be accomplished as required.
Use only forged clips for critical, heavy duty, overhead loads, such as support lines, guy lines, towing lines, tie downs, scaffolds, etc.
Malleable clips are to be 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.
