According to NCCCO guidelines, how many safety turns (wraps) must remain on the hoist drum when the load hook is in its lowest position?

According to NCCCO guidelines, it is necessary to have a minimum of three safety turns (wraps) left on the hoist drum when the load hook is in its lowest position. This requirement is in place to ensure that there is enough rope secured on the drum, maintaining a safe margin that prevents the rope from completely unwinding and potentially leading to a loss of load control. Having three wraps helps to provide stability and reduces the risk of slippage or accidents during operations. This practice emphasizes the importance of safety in crane operations, ensuring that operators have a buffer of securely wound rope regardless of the other operational factors.
