The tower crane is the most commonly used for lifting and moving large loads, such as construction materials and construction equipment. But the tower cranes Australia models are used not only in the construction industry, but also in transportation and cargo industry because it is stable and its base is fixed to the ground.

A typical tower crane consists of a base, a mast section, a jib, a slewing unit, a crane house and a cabin. There are many types of tower cranes for sale, and each one is used for a specific application. The two main tower cranes Australia types are:
