What does a 1 short audible signal indicate when the crane is moving?

• A. Stop
• B. Go ahead
• C. Back up
• D. Pause

Answer: (A)

Audible signals on a crane are used for immediate, clear communication between the signal person and the operator. A single short sound is the stop cue—the operator must halt the crane right away. This immediate stop helps prevent accidents if something isn’t clear or a hazard appears, and it gives the signal person a chance to reassess and relay the next instruction. Different actions, like moving forward, backing up, or pausing, use other signal patterns or lengths, so they aren’t confused with the stop signal. After stopping, the operator waits for a clear instruction before resuming.
