Parts of a Tower Crane

February 1, 2024

The way a tower crane functions has a lot to do with its components. To better understand a tower crane’s abilities, let’s have a look at its essential elements.

Base Support

‌The base support is located at the bottom of the tower and often attached to a concrete pad on the ground. Alternatively, the base support may be attached to a steel grillage or ballasted chassis set on the ground or on top of an existing structure.

Tower

Also known as the mast section, the tower is the vertical element that gives the crane its notable height. This component extends from the ground up, and it supports other elements like the cab, the hook, and the counterweights. Towers often feature steel latticework for extra strength. ‌

Turntable

The turntable is the part of the crane that allows the arm to rotate. This component uses the same technology we often see in windmills. Thanks to it, the jib has a broader range of motion.

Jib or Working Arm

Also known as the crane’s working arm, the jib is the horizontal component sticking out from the top of the tower. This element’s purpose is to support and position the load being lifted. ‌‌

Trolley and Hook Block

‌The trolley is the piece that moves back and forth across the jib. The hook block serves as a pulley system that allows the hook to travel up and down the tower.

Counter Jib

The counter jib extends in the opposite direction of the jib and helps the tower crane maintain its balance.

‌Counterweight

Counterweights balance the load of the lift. Without them, the load capacity would have to be significantly lower to maintain stability. You’ll find this essential element at the rear of the counter jib, opposite of the jib. Some common counterweight materials include reinforced concrete and steel. ‌
