🔍 Key Concepts

• Standard crane hand signals used in marine cargo and shipyard operations • How additional hand positions modify a basic motion signal • Difference between signals for stop, slow, and caution

💭 Think About

• Think about what placing a second hand still in front of the signaling hand would communicate to an operator watching from a distance. • Consider how you might change a normal motion signal if you wanted the crane to move, but not at full speed. • Ask yourself: which of these options most clearly matches the idea of limiting or moderating the motion rather than changing direction or completely stopping?

✅ Before You Answer

• Verify which specific crane signal uses one moving hand and one stationary hand in front of it. • Confirm that the signal you choose is meant to control speed of motion, not to start or stop entirely. • Eliminate any option that would normally be shown by a very obvious, distinct gesture (for example, a full stop).
