During lifting operations, what should be monitored regarding the crane's drum?

Monitoring the number of wraps on the crane's drum is essential for the safe operation of lifting equipment. This is because the wraps indicate how much rope or cable is securely wound around the drum, which directly affects the crane's load capacity and stability. If the wraps are insufficient, there may not be enough friction or grip to safely hold the load, increasing the risk of slippage or equipment failure during lifting operations.

Additionally, maintaining an appropriate number of wraps helps to prevent the rope from overlapping or becoming entangled, which could lead to damage or accidents. By keeping track of the number of wraps, operators can ensure that the crane operates within its designed parameters, promoting safety and efficiency on the job site.
