When can multiple crane functions be executed according to lifting operation protocols?

The ability for multiple crane functions to be executed during lifting operations primarily relies on the signal person’s authority and expertise in coordinating such activities. The signal person plays a crucial role in ensuring safety and proper communication between the crane operator and the rest of the team. When the signal person grants permission, it indicates that they have assessed the situation and deemed it safe to proceed, taking into consideration factors such as load stability, site conditions, and proximity to obstacles or personnel.

This protocol is essential for preventing accidents and ensuring that each lifting operation is conducted smoothly. While the foreman and the operator's awareness are also important, the signal person's responsibility is specifically focused on the real-time coordination of lifting activities, making their approval paramount. Other scenarios, such as merely having a foreman's directives or only during training, do not align with the established operational safety protocols needed in active lifting situations.
