🔍 Key Concepts

• Pedestal crane components – identify what part actually changes the position or angle of the jib/boom versus what just controls the load • Taglines vs. snaking cables – how they’re attached to the rider block or hook to control swing of the load • Luffing system – what wires or cables are used specifically to raise and lower (luff) the jib

💭 Think About

• Look closely at where item K is attached at each end. Is it connected to the load hook, the rider block, or to a point on the jib or pedestal? • Ask yourself what function those cables would serve when the crane is in operation: do they move the jib, control side‑to‑side movement of the load, or help manually swing (slew) the crane? • Compare item K with the main hoist cables and with the cables that obviously change the jib angle. How is K’s routing different?

✅ Before You Answer

• Verify whether item K ever connects directly to the hook block (load) or only to an intermediate block or the jib structure • Check if item K runs in a way that would pull the jib up/down, which would indicate a luffing function • Confirm whether item K appears to be a light control line or a heavy load‑bearing wire; this will help you distinguish between taglines/snaking cables and main hoist or luffing cables
