How should you signal the crane operator to lower?

🔍 Key Concepts

• Standard crane hand signals used in marine and industrial operations • The difference between signals for hoist (raise) and lower • How operators distinguish between boom movement and load line movement

💭 Think About

• Ask yourself: which signal clearly indicates the load line should move down, not the boom moving in or out or up? • Consider which motions (upward vs downward arm position, circular vs flexing fingers) are commonly used to show movement of the hook rather than direction of the boom. • Think about how the operator, from a distance, can easily see the signal and avoid confusing it with a command to move the boom.

✅ Before You Answer

• Identify which options use a downward-pointing arm or finger, since the command is to LOWER. • Separate signals that clearly indicate boom direction from those that indicate hoist/lower of the hook or load. • Verify which signal involves a continuous motion (like a small circular movement) that is typically used to command ongoing movement rather than a momentary indication.
