An arm extended downward with a moving hand in a circular motion in the downward direction instructs the crane operator to lower the load.

Another common signal involves an extended arm pointing in the direction of travel. This signal indicates that the crane operator must move the crane in the specified direction (forward, backward, left, or right). Arm extended horizontally, palm facing downward, and moving hand in a chopping motion instructs the crane operator to stop all crane movements immediately.

Furthermore, an arm extended horizontally, with a moving hand in a circular motion, instructs the crane operator to swing the boom (horizontal arm) of the crane left or right. Both arms extended horizontally, palms facing downward, and moving hands in a chopping motion indicate an urgent need to stop all crane operations immediately due to an emergency.

It’s essential for both the signal person and the crane operator to understand and use standardized hand signals effectively. It ensures ear communication and safe crane operations. Finally, hand signals may vary slightly depending on regional regulations.
