🔍 Key Concepts

• Standard crane hand signals used in maritime and industrial operations • Difference between commands related to vertical movement (up/down) and horizontal movement (side to side) • How hand/arm position and motion indicate the direction of crane boom or load movement

💭 Think About

• What does a vertical forearm with the index finger pointing straight up usually indicate about direction? • If the hand is moving in a small horizontal circle, is that more likely to suggest starting/stopping motion, moving up/down, or swinging side to side? • Which of the choices clearly relates to side-to-side (slewing) movement versus up/down (hoist/lower) or outward (extend) motion?

✅ Before You Answer

• Match arm position (vertical vs horizontal) to typical crane signal meanings • Match hand motion (circular vs straight up/down) to starting a particular type of movement • Eliminate options that describe vertical or boom-length movement if the signal clearly suggests rotational/slewing motion
