The maximum number of broken wires allowed within 6 rope diameters for rotation resistant wire rope is indeed two. This criterion is based on industry safety standards, which are designed to ensure the integrity and safety of the wire rope used in lifting operations.

Rotation resistant wire rope is designed to minimize rotation during lifting, making it essential for applications where load control and stability are critical. The presence of broken wires can compromise the rope's strength and functionality, leading to potential failures if not managed properly. Therefore, establishing a limit of two broken wires within a specific section of the rope helps to maintain a safety threshold while allowing for the normal wear that can occur in such equipment.

Exceeding this limit can lead to significantly reduced structural integrity, increasing the risk of catastrophic failure. Thus, adhering to this standard is vital for the safe operation of cranes and lifting equipment.
