In lifting operations using voice signals, who is responsible for permitting multiple simultaneous crane functions?

The lift director is responsible for overseeing the entire lifting operation, which includes coordinating various aspects of the lift to ensure safety and efficiency. This role involves determining when multiple simultaneous crane functions can be executed safely, which requires a comprehensive understanding of the operational environment, load dynamics, and communication among all parties involved.

By permitting multiple crane functions, the lift director ensures that the operation follows established safety protocols and that all team members are aware of their roles and positions at all times. Adequate planning and clear communication are crucial, especially when multiple operations are conducted concurrently, to prevent accidents or miscommunication that could lead to hazardous situations.

The other roles, such as crane operator, signal person, and site supervisor, have specific responsibilities during the lifting process but do not have the overarching authority to permit simultaneous functions without the lift director's oversight and directive.
