When the hoist of a traveling crane is to be raised, you should signal by which gesture?

• A. holding the palm of your hand up with your fingers closed, pointing your thumb in the direction of motion, and jerking your hand horizontally
• B. extending your arm forward with your hand open and slightly raised, and making a pushing motion in the direction of travel
• C. extending your arm with the palm of your hand down, and moving your arm back and forth horizontally
• D. holding your forearm vertical with your forefinger pointing up and moving your hand in a small horizontal circle

Answer: (D)

In crane signaling, clear, standardized gestures tell the operator exactly what to do without verbal cues. To raise the hoist, extend your arm with the forearm vertical, point your forefinger upward, and move your hand in a small horizontal circle. That specific combination communicates the command to hoist upward, and the circular motion confirms the action should continue as you request. It’s distinct from signals for traveling, lowering, or stopping, which use different arm positions and motions, so using this gesture helps keep the lift safe and coordinated.
