What is the maximum number of broken wires allowed beyond end connections in a standing wire rope?

The maximum number of broken wires allowed beyond end connections in a standing wire rope is two. This standard is established to ensure the integrity and safety of the wire rope during operation. Wire ropes are critical components in lifting and rigging applications, and any deterioration can compromise their strength and reliability.

Having up to two broken wires is considered acceptable because it indicates that the rope is still capable of bearing loads without immediately failing. If the number of broken wires exceeded this limit, it could be a sign of significant wear or damage, which could lead to failure under load. The allowable number is designed to balance safety with practicality, acknowledging that wire ropes can experience wear and tear over time.

Maintaining this standard is crucial for safe crane operation, as it helps prevent accidents that could arise from using equipment that is not in optimal condition. If more than two broken wires are found, it's typically required to replace the rope immediately to avoid putting operators and loads at risk.
