Which signal indicates that the crane operator should lower the load?

The signal that indicates the crane operator should lower the load involves a hand position that is easily recognizable and widely understood in the construction industry. The correct answer, with the palm facing down and fingers closed, effectively communicates the message to the operator that the load should be lowered. This particular signal is practical because it is distinct and minimizes confusion, clearly differentiating it from other signals used during crane operations.

Using a palm-down position ensures that the operator sees a clear downward gesture, which and effectively keeps both the signal person and operator synchronized in their actions. This is crucial for maintaining safety and efficiency on the worksite. The method also aligns with common practices outlined in hand signal guidelines, reinforcing safe communication standards.

In contrast, the other options do not convey the lowering action as clearly. Gestures like waving arms downward might be interpreted as a signal to stop or hurry up rather than specifically lowering the load. A hand signal with one arm raised is typically used to indicate a stop or to command attention. Circular motion with fingers pointing down could suggest a different action entirely, likely indicating a turn or repositioning rather than a lowering motion.
