• Mast: the main supporting tower of the crane. It is made of steel trussed sections that are connected together during installation.
• Slewing unit: the slewing unit sits at the top of the mast. This is the engine that enables the crane to rotate.
• Operating cabin: the operating cabin sits just above the slewing unit. It contains the operating controls.
• Jib: the jib, or operating arm, extends horizontally from the crane. A "luffing" jib is able to move up and down; a fixed jib has a rolling trolley that runs along the underside to move goods horizontally.
• Counter jib: holds counterweights, hoist motor, hoist drum and the electronics.
• Hoist unit: the hoist unit houses the hoist drum, hoist cable, gear box, gear shift, brake, and supporting components.
• Hook: the hook (or hooks) is used to connect the material to the crane. It hangs at the end of thick steel cables that run along the jib to the motor.
• Weights: Large concrete counterweights are mounted toward the rear of the mast, to compensate for the weight of the goods lifted.
