A tower crane is an advanced balance crane that comprises of similar basic parts. The crane is attached to the ground using a concrete slab. Sometimes it is connected to the sides of the structures. Tower cranes are known for giving the ideal combination of lifting capacity and height and are often used for constructing buildings.
Then the base is connected to the mast, which gives the unit the height it requires. Moreover, the mast is connected to a gear and motor, which is also called the slewing unit. It allows the crane to rotate. The upper part of the slewing unit features three primary components: the operator’s cab, the shorter counter-jib, and the jib, which is also known as the working arm.
