What is the maximum number of broken wires permitted at a wire rope terminating fitting?

The maximum number of broken wires permitted at a wire rope terminating fitting is one. This guideline exists to ensure the safety and integrity of wire ropes used in applications like mobile cranes and other lifting equipment. Wire ropes are designed with multiple strands, and if too many wires are broken, the rope's tensile strength is compromised, significantly increasing the risk of failure.

Having one broken wire may indicate wear and tear, and while it may not immediately compromise the rope's integrity, it serves as a warning sign that inspection and maintenance are necessary. If a fitting has more than one broken wire, it suggests that the rope is more severely damaged, requiring immediate attention or replacement to avoid potential hazards.

By maintaining the guideline of one broken wire, safety standards are upheld, thus protecting both equipment and personnel during operations.
