Components of A Tower Crane

A Tower Crane is comprised of the following parts:

1. Tower Crane Base

Foundation base is the most crucial part of the tower crane that supports the entire structure. It is made of concrete that has been poured a few weeks before the crane assembly commences. The crane is anchored to this base.

2. Tower Crane Mast Section

The mast section of tower crane refers to the truss-shaped columns that give the crane its working height. Instead of being one continuous column, they are designed to be bolted to each other and other crane components. The concrete base and the mast columns impart stability to the crane and prevent it from toppling over.

3. Tower Crane Slewing unit

The slewing unit comprises a gear and motor arrangement, enabling the crane to rotate.

4. Tower Crane Jib

Also known as the jib, this extends perpendicular to the mast section, and houses the hook and trolley that lift the load.

5. Tower Crane Machinery Jib

Also known as the counter jib, this houses the counterweights and pulleys that balance the crane.

6. Tower Crane Hook and trolley

The hook is the main load-bearing component that hauls loads. It is attached to a trolley that allows the hook to raise and lower, as well as move towards and away from the mast. This is done with the help of cables and pulleys attached to the trolley.

7. Tower Crane Operator Cabin

This is the control center of the crane and is attached to the slewing unit. In order to get to the cab, the operator must climb a series of ladders within the mast.
