According to OSHA, what is the minimum number of wraps of wire rope that must remain on the drum with the hook at its lowest point?

The minimum number of wraps of wire rope that must remain on the drum with the hook at its lowest point being set at two is based on safety considerations. This requirement is crucial for maintaining the integrity and reliability of the lifting operations. By ensuring at least two wraps of wire rope are left on the drum, the crane can maintain proper tension and control over the load being lifted, reducing the risk of slippage or potential accidents. The additional wraps increase the friction on the drum, providing a better grip, which is essential for safe operation.

This standard is aligned with OSHA regulations, which emphasize the importance of safe working conditions in environments where cranes and other lifting equipment are used. Meeting this minimum ensures that operators can effectively manage loads and enhance workplace safety.
