How should you signal the crane operator to raise the boom?

🔍 Key Concepts

• Standard crane hand signals used in marine and industrial operations • The difference between signals for raise boom, hoist load, and raise boom & lower load • Why thumb direction and finger motion matter in crane signaling

💭 Think About

• Which part of the signal usually indicates the direction of boom movement (up or down)? • In standard crane signals, what hand or finger action is commonly used to show boom movement without hoisting the load? • Look for the choice that clearly distinguishes raising the boom from simply hoisting the hook straight up.

✅ Before You Answer

• Verify which option uses the thumb to indicate the upward boom direction • Check which signal shows hand/finger motion that is associated specifically with boom movement, not just hook movement • Eliminate any options that look like signals for hoist load or raise boom & lower load rather than just raise boom
