Which hand signal indicates to the operator to raise the load?

• A. A raised arm with an open hand signaling upward movement
• B. A nodding head with both hands raised
• C. A waving hand signaling to stop
• D. Both arms crossed in front of the body

Answer: (A)

The signal to raise the load is correctly represented by a raised arm with an open hand signaling upward movement. This specific hand signal is universally recognized in the field of signaling for cranes and heavy machinery operations. When one arm is raised, it clearly communicates to the operator that the load should ascend. The open hand helps to reinforce the idea of moving the load upwards, as it visually indicates the desired direction of movement. In contrast, the other signals convey different messages or actions. For instance, a nodding head with both hands raised generally does not pertain to signaling for load movement, making it ineffective in this context. A waving hand signaling to stop is designed specifically to instruct the operator to halt any action, which is the opposite of raising a load. Lastly, crossing both arms in front of the body typically signifies a stop or a warning, rather than movement. Therefore, the correct hand signal for raising the load is represented by a single raised arm with an open hand indicating upward motion.
