What hand signal is used to indicate tilting the mast back?

The hand signal used to indicate tilting the mast back is represented by having the forearm vertical and the thumb extended, with a jerking motion of the thumb over the shoulder. This specific gesture is widely recognized within the hoisting and rigging industry as a clear and definitive signal to operators. It effectively communicates the desired action of tilting the mast away from the load, facilitating safe and precise handling of equipment during operation.

This choice aligns with standard signaling protocols, where the vertical forearm indicates the operator's focus and the thumb gesture shows the exact movement required. Effective communication through hand signals is crucial in ensuring safety and efficiency on job sites, especially when machinery or heavy loads are involved. Recognizing and using this specific signal helps prevent misunderstandings between the signaler and the machinery operator.
