What does a signal using both arms raised overhead mean?

The signal using both arms raised overhead indicates that the load needs to be raised or lifted higher. This clear signal is universally recognized in crane operation contexts, ensuring that crane operators and crew members understand the intent to elevate the load. The upward positioning of the arms communicates to everyone involved that the current load height is insufficient and that an increase in elevation is necessary for safety and operational efficiency.

Understanding this signal is critical since miscommunication in crane operations can lead to accidents or unsafe conditions. Knowing the correct arm signal helps maintain a cohesive work environment and ensures that the lifting operation proceeds smoothly and effectively.
