Which hand signal indicates the operator should "Hoist"?

The hand signal that indicates the operator should "hoist" is represented by raising one hand above the head. This signal is universally recognized within the rigging and crane operation industry, as it clearly conveys the directive to lift the load upwards. By positioning the hand high, it signifies to the operator that the action required is an upward motion, eliminating any ambiguity.

In the context of crane operations, clarity in communication is crucial for safety and efficiency. Raising the hand above the head is a distinctive position that can easily be seen from a distance, ensuring that the operator can quickly respond to the command. This signal is part of standard hand signals utilized in rigging to ensure a synchronized operation between the rigger and the crane operator.

The other options, while they may imply some form of action or communication, do not specifically convey the directive to hoist as effectively. For instance, pointing upward may suggest a general direction rather than a specific command. Thumbs up usually indicates approval or confirmation, which does not directly correlate with the action of hoisting. Similarly, raising two hands can be interpreted in various ways and does not clearly align with the singular instruction to lift the load. Thus, raising one hand above the head is the most appropriate and standardized signal for
