What action does the signal for "lower load" involve?

The signal for "lower load" is represented by moving one arm downwards with the palm facing down. This action clearly communicates to the operator that the load should be lowered. The downward movement of the arm is intuitive, as it mimics the desired action of bringing the load closer to the ground. Furthermore, the palm facing down provides additional clarity, signaling that the load should descend in a controlled manner. This method is effective in ensuring that the communication is immediately understood by the crane operator, enhancing safety on the job site. It reflects standard signaling practices that are commonly implemented for crane operation.
