Which role is responsible for controlling the personnel platform's movements during hoisting?

The signalman plays a crucial role in controlling the personnel platform's movements during hoisting operations. This individual is specifically trained to communicate with the crane operator using standardized hand signals or radio commands, ensuring that the platform is moved safely and efficiently. The signalman must have a thorough understanding of the lift plan, the equipment being used, and the surrounding environment to provide clear instructions that facilitate safe operations.

In contrast, while the supervisor, crew leader, and safety officer all have vital roles in overseeing the overall safety and efficiency of the project, their responsibilities do not typically involve direct control of the personnel platform's movements. The supervisor focuses on managing the entire operation and coordinating the workforce, the crew leader directs the work of the crew under their guidance, and the safety officer ensures that safety protocols are being followed throughout the operation. However, it is the signalman who has the specialized training and direct authority when it comes to controlling the maneuvers of equipment during the hoisting process.
