Which signal indicates that the lifting movement should pause and the crane locked in position?

• A. Hoist
• B. Emergency Stop
• C. Voice Signals
• D. Reeving

Answer: (B)

Stopping lifting motion quickly and securing the crane is a safety-critical action. An emergency stop immediately cuts power and applies the brakes to halt all motion and hold the load in place. This is why it’s the best choice when you need the crane paused and locked in position—the signal is specifically designed to terminate movement and secure the system. Hoist signals indicate lifting or lowering actions, but they don’t automatically immobilize the crane. Voice signals are a communication method, not a control that stops movement. Reeving relates to the arrangement of the rope around sheaves and isn’t used to stop or lock the crane.
