How should you signal the crane operator to swing?

🔍 Key Concepts

• Standard crane hand signals used on U.S. vessels and docks (often based on OSHA/ASME standards) • Difference between signals for boom up/down, swing, and hoist/lower • How signals that indicate direction of movement are usually given

💭 Think About

• Identify which option looks like a signal for horizontal rotation of the boom (turning left/right) rather than up/down or in/out • Ask yourself: when an operator must know which way to turn the boom, what simple body motion best shows that direction? • Compare which choices seem to describe vertical movement versus horizontal swinging of the boom

✅ Before You Answer

• Verify which signals obviously relate to up/down movement and rule those out for a swing command • Check which option uses a single clear pointing direction that could match left or right swing • Confirm that the signal you choose would be easy for the operator to see and interpret quickly from a distance
