What does a signal given at knee height usually communicate?

• A. To raise the load
• B. To lower the load
• C. To move the load sideways
• D. To pause the operation

Answer: (B)

A signal given at knee height typically communicates the instruction to lower the load. This convention is widely used in signaling to ensure clear and consistent communication between the signal person and the crane operator. The position of the signal is intentional, as it aligns with the visual range of the operator and can be easily perceived during operation. Communicating a lowering motion helps to maintain safety on the job site by clearly indicating the desired action, allowing the operator to respond appropriately. Understanding these visual cues is critical for effective communication and coordination in heavy lifting operations, where misinterpretation of signals could lead to accidents or damage to equipment.
