What does the crane signal indicated by palms up, fingers crossed, and thumb pointing indicate?

The crane signal indicated by palms up, fingers crossed, and thumb pointing is used to signify "Travel the trolley." This signal communicates the need to move the trolley or hoist along its beam or track. The palms up gesture combined with the fingers crossed conveys a clear visual directive for the operator to execute this specific movement.

Understanding the function of crane signals is vital in ensuring safety and efficiency during lifting operations. Each gesture corresponds to precise commands that help prevent accidents and miscommunication among the crew members involved in the operation.
