Which statement is TRUE regarding the operation of a crane?

🔍 Key Concepts

• Difference between hoisting and luffing functions on a crane • What part is the jib and what part is the cargo block • Which motion changes the angle of the jib versus raising/lowering the load

💭 Think About

• Ask yourself: which system on a crane controls the vertical movement of the load itself, and which controls the angle of the jib or boom? • Think about what happens if you want to keep the cargo at the same height but swing it closer or farther from the ship—what needs to move? • Match each winch name with its primary job: hoisting vs luffing vs jibing—what motion does each word suggest?

✅ Before You Answer

• Be clear on the definitions of hoisting (lifting the load) and luffing (changing jib angle). • Identify whether the cargo block or the jib is being moved in each choice. • Eliminate any answer that assigns the wrong motion (hoisting vs luffing) to the wrong part (jib vs cargo block).
