During the hoisting of a personnel platform, who must the ground signalman maintain continuous communication with?

The ground signalman must maintain continuous communication with both the crane operator and the occupants of the personnel platform to ensure safety and efficiency during the hoisting operation. This dual communication is critical because the signalman needs to convey essential information and instructions from the crane operator to the platform workers and vice versa.

For example, if the crane operator intends to lift the platform, the signalman must signal the workers to be prepared and make sure they are ready to safely be lifted. Additionally, if there are issues or concerns from the platform workers, they can relay that information back through the signalman to the crane operator, preventing potential accidents or misunderstandings. This effective communication loop is vital for maintaining safe work conditions and ensuring that all parties are aware of the operation's status and any potential hazards.

Effective communication is essential in operations involving personnel platforms, as it not only protects the individuals on the platform but also ensures that the crane operator is accurately informed of the conditions and needs at all times. Other groups, such as the safety supervisor or ground crew, play important roles, but the primary focus during hoisting is on communication directly between the crane operator and those on the platform.
