What is the proper signal for "Move Forward"?

The proper signal for "Move Forward" is to extend one arm with the palm facing the operator. This signal effectively communicates the intention for the crane or load to move forward in a clear and direct manner. Extending a single arm with the palm outward provides a visual indication and is widely recognized in crane signaling practices as a method to guide the operator without ambiguity.

Using one arm allows for better visibility and understanding, especially in environments where multiple signals may be in use. It is essential that the signal appears distinct to avoid confusion with other possible commands. In contrast, signals such as waving both arms or raising both arms above the head may not convey the intended action as clearly, as they can be misconstrued or used for different purposes. Additionally, pointing in the direction of movement, while helpful for indicating direction, does not provide the explicit command that "Move Forward" requires. The one-arm palm-facing signal is standardized and thus, more effective for communication in crane operations.
