🔍 Key Concepts

• Standard crane hand signals used in maritime and construction operations • How arm position (up, down, horizontal) typically relates to hoist vs. lower vs. swing • How hand motion (circular vs. side-to-side vs. stationary) changes the meaning of the signal

💭 Think About

• Ask yourself: when the forefinger is pointing down, does that usually relate more to moving the hook up, moving it down, or moving it sideways? • Consider what a small horizontal circular motion of the hand would reasonably tell the operator to do with the boom or hook. • Think about which option (swing, lower, hoist, extend) most logically matches a signal that emphasizes direction of the hook rather than the boom length.

✅ Before You Answer

• Match the arm position (down vs. up) with common meanings: hoist vs. lower. • Match the finger direction (pointing down) with the likely motion of the hook or load. • Confirm whether a circular motion usually means to start/continue motion in that direction, rather than changing the boom length (extend) or only moving sideways (swing).
