Which signal instructs both boom up and hoist movement?

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

Answer: (A)

Some crane hand signals are designed to move more than one function at once, so operators can coordinate actions without sending multiple commands. The signal that commands both raising the boom and lowering the hoist communicates two actions in one gesture, so the operator knows to perform both movements together. This makes it the best choice when you need simultaneous control of the boom and the hoist.

Signals that move only the hoist or only the boom don’t address both parts, and a signal like move slow is about the speed of movement rather than which parts are moving.
