Which gesture indicates the bridge should be moved?

• 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: (B)

The move signal is a clear forward push. Extend your arm straight ahead, keep the hand open with the palm facing forward and slightly raised, and push in the direction you want the bridge to travel. This straightforward, outward motion tells the operator to move the bridge along the crane’s path without ambiguity. It’s a standard way to indicate linear movement, making it easy to read in a busy, noisy work environment. Other gestures convey different actions: a quick jerk with the thumb in the travel direction isn’t a standard move signal, a palm-down motion from side to side suggests stopping or stabilizing rather than moving forward, and a vertical forearm with a small circular wrist motion signals rotation rather than linear travel. Keeping to the forward push ensures safe, coordinated operation.
