What is the maximum number of broken wires allowed at an end connection before a standing wire rope must be replaced?

The correct answer is that only one broken wire is permitted at an end connection before a standing wire rope must be replaced. This standard is in place because the end connection is a critical area where the integrity of the wire rope is vital for safety and performance.

When there is a broken wire at the end connection, it can significantly compromise the strength and reliability of the wire rope, potentially leading to failure during operation. Replacing a wire rope after even just one broken wire at the end connection helps prevent accidents and ensures the equipment operates safely.

Understanding this maximum limit reinforces the importance of regular inspections and maintenance. Operators must be diligent in monitoring the condition of wire ropes, especially at key stress points such as end connections, to maintain the highest safety standards in crane operations.
