What is indicated if an operator makes two audible signals when moving a crane?

  1. He/she intends to stop

  2. He/she intends to back up

  3. He/she intends to go ahead

  4. He/she intends to stop (emergency)

The correct answer is: He/she intends to go ahead

When an operator makes two audible signals while moving a crane, this typically indicates an intention to go ahead. This is a standard practice within the industry to communicate the movement of the crane to those in the vicinity, ensuring that everyone is aware of the operator's actions. Making two signals serves as a clear and distinct message to alert personnel of the crane's intended forward motion, promoting safety on the job site. The interpretation of the signals is aligned with crane operation protocols designed to prevent accidents and ensure effective communication in potentially hazardous environments. Proper signaling not only reinforces operational safety but also helps maintain awareness among ground personnel regarding the crane's movements.
