Which condition indicates replacement due to damage when a wire is near an end fitting?

• A. 6 broken wires in one rope lay length
• B. 3 broken wires in one strand lay length
• C. Wear 1/3 of the original diameter
• D. 1 broken wire within one rope lay length of any end fitting

Answer: (D)

End fittings create concentrated bending and wear on a wire rope. A single broken wire within one rope lay length of any end fitting means the rope near the termination has been damaged where stresses are highest, and this situation greatly increases the risk of sudden failure under load. Because damage here can propagate quickly, replacement is required to maintain safety. Other conditions describe broader internal wear or damage, not specifically at the end fitting area. Six broken wires in one rope lay length indicates substantial internal damage, but not the end-fitting proximity that this question emphasizes. Three broken wires in one strand lay length is also serious but localized to a strand, not the end region. Wearing down to one-third of the original diameter is a general wear criterion, not necessarily tied to end-fitting damage. So the statement about a broken wire within the end of the rope lay length clearly signals replacement due to damage near the end fitting.
