If the operator sounds two short audible signals while moving the crane, what is the intended action?

When an operator sounds two short audible signals while moving the crane, the intended action is to inform others that it is safe to proceed or that the crane is beginning movement. This signaling is a standard communication practice designed to ensure that everyone on site is aware of the crane's actions and can take the necessary precautions.

In many operational environments, two short signals typically indicate that the operator is ready to start moving and expects others in the vicinity to remain clear or maintain safety awareness. This clear communication helps prevent accidents and ensures a coordinated operation on site.

Other potential answers do not align as closely with industry norms for signaling. For instance, instructions to stop immediately or to move in reverse would not correspond with the meaning of two short signals, as they imply an action that opposes the initiation of movement. Similarly, proceeding with caution suggests that there is still some uncertainty or hazard, which does not accurately reflect the clarity intended by the two short signals indicating readiness to move forward.
