Which signal governs the hoist operation?

• A. The signal for hoist
• B. The signal for move slow
• C. The signal for stop
• D. The signal for lower boom

Answer: (A)

The main idea here is that lifting or lowering the load is controlled directly by the hoist signal. When the signaler directs the hoist, the operator engages the hoist mechanism to raise or lower the load. Signals about speed (move slow), stopping (stop), or boom movement (lower boom) govern other actions or aspects of the crane’s operation, not the actual hoisting of the load. So the signal dedicated to hoist is the one that directly initiates and controls the lifting action, making it the correct choice.
