Some parts
1. The External climbing tower cranes is fixed to the ground on a
concrete base.

height.
3. Further the mast is attached to the slewing unit that allows the
crane to rotate.

the long horizontal jib, shorter counter-jib, and the tower head.

the load.

blocks, while the jib suspends the load to and from the center of
the crane.
7. The crane operator either sits in a cab at the top of the tower
or controls the crane by radio remote control from the ground. In
the first case the operator's cab is most usually located at the
top of the tower attached to the turntable, but can be mounted on
the jib, or partway down the tower.
8. The lifting hook is operated by the crane operator using
electric motors to manipulate wire rope cables through a system of
sheaves.
