Which type of signals controls the lifting and landing of a load?

Standardized arm signals are essential for controlling the lifting and landing of loads in industrial rigging and lifting operations. These signals provide a clear and universally understood method of communication between the signaler and the operator, especially in environments where noise can make verbal communication difficult or impossible.

The use of standardized arm signals helps ensure safety and efficiency by minimizing misunderstandings and errors during potentially hazardous lifting operations. These signals typically convey specific instructions, such as when to lift, lower, or stop, thereby enhancing coordination and ensuring that both the operator and any ground personnel are in sync regarding the movement of the load.

While hand signals, voice commands, and light signals can also be used in some circumstances, standardized arm signals are particularly favored in rigging practices because they are specifically designed to be universally recognized within the field, reducing the risk of miscommunication. This makes them a cornerstone of effective rigging practices in various industrial settings.
