the component of the tower cranes

Tower Crane are used extensively in construction and other industry to hoist and move materials. There are many types of tower cranes. Although they are different in types, but The main parts are the same.

Now let us introduce the component of the tower cranes as follows:

1. Mast
The mast is the main supporting tower of the crane. It is comprised of steel trussed sections that are connected together during installation.
2. Slewing Unit
The slewing unit sits at the top of the mast. This is the engine that enables the crane to rotate.
3. Operating Cabin
The operating cabin sits just above the slewing unit. It contains the operating controls.
4. Jib
The jib, or operating arm, extends horizontally from the crane. A "luffing" jib is able to move up and down; a fixed jib has a rolling trolley that runs along the underside to move goods horizontally.

5. Hook
The hook (or hooks) is used to connect the material to the crane. It hangs at the end of thick steel cables that run along the jib to the motor.
6. Weights
Large concrete counterweights are mounted toward the rear of the mast, to compensate for the weight of the goods lifted.
