What is the minimum distance between splices, sleeves, or end fittings on wire rope slings?

• A. 5 rope diameters
• B. 10 rope diameters
• C. 15 rope diameters
• D. 20 rope diameters

Answer: (B)

The minimum distance is ten rope diameters. This spacing protects the splice or sleeve from excessive bending and wear near the end fittings when the sling is loaded. If the termination is too close to a fitting, stress concentrations and abrasion can develop, shortening the sling’s life or risking failure. Keeping a length of rope equal to ten diameters between any splice, sleeve, or end fitting and the adjacent fitting allows better load distribution, reduces wear, and helps the sling perform safely over its service life. For example, if the rope diameter is 1/2 inch, the required gap would be 5 inches.
