What signal is used to retract a telescoping boom?

The signal used to retract a telescoping boom is represented by both fists in front of the body with the thumbs pointing toward each other. This specific hand signal indicates to the operator that the boom should be pulled back or retracted.

In the context of crane operations and hoisting, clear communication between the signal person and the operator is crucial for safety and efficiency. Using standardized signals helps to prevent misunderstandings that could lead to accidents or improper maneuvers. The thumbs pointing toward each other effectively indicate the action of moving inward or retraction, which is pertinent when managing the movements of a telescoping boom.

Other signals provided in the options refer to different actions or movements unrelated to the retraction of the boom. It is important for anyone involved in hoisting operations to be familiar with these signals to ensure a safe working environment.
