Which hand signal indicates that the mast should be tilted forward?

The hand signal that indicates the mast should be tilted forward involves extending the arm with the thumb pointing down and the lower arm positioned vertically. This particular gesture is widely recognized in the field as a clear and unambiguous way to convey the command to lower or tilt the mast forward. The positioning of the arm and thumb creates a visual indicator that operators and ground personnel can easily interpret, ensuring effective communication during hoisting operations.

This clarity in signaling is essential in maintaining safety and preventing miscommunication on construction sites, where understanding commands quickly can prevent accidents. The other gestures suggest different movements that do not communicate the action of tilting the mast forward, which can lead to confusion in an already dynamic work environment.
