What signal is given for "raise load" in crane operations?

The signal for "raise load" in crane operations involves one arm being raised upward with the palm facing upwards. This widely recognized communication indicates to the crane operator that they should lift or elevate the load. The upward arm position is intuitive, demonstrating the action of lifting, and the orientation of the palm ensures clarity, as it visually suggests direction and intent.

This signaling practice is essential for maintaining safety and effective communication on the job site, as it reduces the chance of misinterpretation during complex operations. Proper understanding and execution of these signals contribute to the safety of personnel and efficient handling of materials during crane operations.
