Which signal should be used to move the crane slowly?

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

Answer: (A)

Controlling how fast the crane moves is a key safety and precision factor in crane operations. The signal for moving slowly directly communicates to the operator to reduce the travel speed, allowing careful positioning of the load, minimizing sway, and ensuring safe clearance around obstacles or people.

This is the best answer because it precisely conveys a speed instruction rather than altering the load or the boom. The signal for stop would halt movement, not slow it, while the signals for hoist or boom up instruct lifting or changing the boom angle, not simply reducing travel speed. Using the slow signal keeps the crane moving, but at a controlled, safer pace.
