What are the main parts for tower crane?

Tower cranes in general are composed of three main parts: the base, the mast or tower, and the slewing unit.

1. The base is bolted to a large concrete foundation that supports the crane.

2. The base connects to the mast section, which gives the tower crane its height.

3. The slewing unit consists of a gear and motor, attached to the top of the mast, allowing the crane to rotate along its axis. In turn, the slewing unit consists of three parts:

1) Jib (Working arm): A horizontal element that carries the load, with a trolley that runs along its length to move the load in and out.

2) Machinery arm(Counter Jib): A shorter horizontal element that holds the hoisting motor. It also contains electronic controls, the cable drum, and concrete counterweights to keep balance.

3) Operator’s cabin: Consists of the space in which the operator handles all the functions of the crane.
