Using wire rope clips is essential for securely fastening the ends of a wire rope or cable to create a loop, often necessary for rigging or lifting operations. Here’s a step-by-step guide for correct usage:
1. Determine the Number of Clips Required
-
The number of clips needed depends on the wire rope diameter. Smaller diameters need fewer clips, while larger diameters require more for secure fastening.
-
Always check the clip manufacturer’s recommendations or refer to industry standards to determine the exact number of clips needed.
2. Position the First Clip (Live-End Clip)
-
Start by placing the first clip one saddle width from the end of the wire rope “live end” (the main line that will bear the load).
-
Ensure that the U-bolt is on the “dead end” (loose end) of the rope, and the saddle is on the live end. Remember, “Never saddle a dead horse” (meaning the saddle should never be placed on the dead end of the rope).
3. Install the Second Clip
-
Place the second clip as far from the first clip as recommended (usually a minimum of 6 rope diameters away).
-
Follow the same orientation: the U-bolt on the dead end and the saddle on the live end.
4. Install Additional Clips
-
For larger ropes that require additional clips, distribute the clips evenly between the first two.
-
Always double-check that each clip follows the same orientation rule.
5. Tighten the Nuts
-
Use a torque wrench to tighten the nuts on each clip to the recommended torque values. Avoid overtightening, as this can damage the wire rope.
-
After initial tightening, check each clip again in sequence to ensure they are equally torqued.
6. Load Test and Retighten
-
Apply a load to the wire rope (not exceeding the working load limit) to test the security of the clips.
-
Re-torque the nuts after load testing, as some initial settling of the clips and wire strands can occur.
7. Regular Inspections and Maintenance
-
Regularly inspect the clips for tightness and check for any wear, corrosion, or damage to the rope. Retighten nuts periodically to ensure ongoing security.
By following these steps carefully, wire rope clips can provide a strong, reliable fastening for loops or terminations in wire rope applications. For more guidance on wire rope and related products, please contact us:
