What is the threshold number of randomly broken wires that results in the removal of a running wire rope from service?

The correct threshold for the number of randomly broken wires that necessitates the removal of a running wire rope from service is indeed six. This standard is based on industry safety practices which account for the structural integrity and safety of the wire rope.

When a wire rope is used, it undergoes repetitive stress and strain, which can lead to wire breakage. The recommended limit of six broken wires serves as a critical safety measure because it helps to ensure that the rope can still maintain its strength and function safely. If too many wires are broken, it significantly compromises the rope’s ability to carry loads, increasing the risk of failure during operation.

Understanding this threshold is vital for operators to maintain safety and compliance. It is also important for them to conduct regular inspections to identify any signs of wear and damage, which will help in preventing accidents that could arise from using compromised equipment.
