🔍 Key Concepts

• Understand the difference between boom luffing (raising/lowering the boom) and cargo hoisting (raising/lowering the load). • Identify which wire runs between the boom tip sheave and the crane structure, versus which wire runs between the boom tip sheave and the cargo block. • Recognize what a tagline system is used for on a crane (controlling the swing of the load, not lifting or luffing).

💭 Think About

• Look at where item "A" is secured at each end: Is it working the boom itself, or the cargo block and hook? • Compare item "A" with the wires marked near the cargo block and hook (around labels C and D). How do their paths and purposes differ? • Think about which line would change the angle of the boom and which would change only the height of the load.

✅ Before You Answer

• Verify whether item "A" runs along the top of the boom and reeves through sheaves that connect back to the crane mast/structure. • Check if item "A" is connected directly to the cargo hook block or if a different set of falls (near B, C, or D) serves that purpose. • Confirm that a tagline is usually a relatively small line attached to the load block or load, used to control swinging, not a multi‑part heavy wire rope along the boom.
