Components

Mast: the main supporting tower of the crane. It is made of steel trussed sections that are connected together during installation.

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.

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.
