What is the hand signal for "move slowly"?

The hand signal for "move slowly" is represented by moving one arm in a circular motion overhead. This specific motion is universally recognized in crane signaling to communicate to the operator to decrease their speed and handle the load with greater care. The overhead position of the arm emphasizes visibility and clarity for the operator at a distance, ensuring that the signal can be easily observed from various angles.

In the context of crane operations, clear communication is critical to maintaining safety and efficiency on the job site. The circular motion conveys not only to move slowly but to do so with a continuous and smooth movement, which is essential in preventing abrupt actions that could lead to accidents or mishandling of loads. Proper understanding and execution of this signal can greatly enhance safety for all personnel involved in the lifting operation.
