🔍 Key Concepts

• Look closely at how item E is drawn compared to the heavier hoisting wires and blocks • Think about what line on a crane is used by deck crew to control the swing and rotation of the load, not to lift it • Recall that power or control cables usually run along the boom or structure, while load‑bearing wires go over sheaves (pulleys)

💭 Think About

• Does item E appear to be carrying the weight of the hook and cargo, or just attached to the hook block for manual control? • If you followed item E back toward the ship, who would likely handle it and for what purpose? • Which of the answer choices names a line that is normally light, often shown as a dashed line, and kept in crew’s hands to steady the load?

✅ Before You Answer

• Verify that E does not pass over any sheaves like the main hoist wire does • Confirm whether E is attached to the hook block but leads off to the side, not up to the boom head or machinery • Match this function (controlling swing of the load from the deck) to the most appropriate term among the choices
