🔍 Key Concepts

• Standard crane hand signals used on construction and waterfront job sites • Difference between a motion command (telling the crane to move) and a safety command (telling it to remain as is or stop) • How a rigid, unmoving arm signal compares to a moving arm signal (like up-and-down or side-to-side)

💭 Think About

• Ask yourself: when the signalman wants the operator to move the load, does the arm usually stay rigid or does it move in a pattern? • Think about what an extended arm with palm down, held steady might communicate to someone controlling heavy equipment—does it suggest motion, or holding/halting? • Compare this signal with what you would naturally do with your hand if you urgently wanted a vehicle or machine to keep still.

✅ Before You Answer

• Verify which signals involve an up-and-down motion of the arm or hand versus a stationary, rigid position. • Check which of the listed options is commonly associated with a safety/precautionary action rather than a directional movement. • Confirm that the option you choose matches a signal that could be easily seen and clearly interpreted from a distance by the crane operator.
