what part of the crane is used to lift and lower the load?

The part of the crane that is used to lift and lower the load is the hoist, or hoist drum. The hoist is located on the horizontal beam of the crane and uses a cranking mechanism and a wire rope to raise and lower the hook. The hook is attached to an electric motor-controlled steel cable, and the hoist drum creates the lift by winding the cable around it. The wire ropes used in the hoist are heavy-duty cables made of steel wires twisted into the shape of a helix, and several of these helixes are twisted together to create an even stronger rope. The hoist is a crucial part of the crane that gives it the strength to lift heavy objects with the hook.
