In a system with multiple hoist cranes, the signal indicates which hook to use. Which hook is indicated?

• A. Hook A
• B. Hook B
• C. Hook C
• D. Hook D

Answer: (C)

In a system with several hoist cranes, the signal given by the signaler designates exactly which hook the operator should use for the lift. This keeps the load on the intended hook and prevents cross-loading or collisions. The signal shown aligns with the third hook in the set, so that is the hook the operator should select. If the signal indicated a different hook, the corresponding hook would be used instead, as the signaling scheme maps each hook to a specific signal position.
