Some parts
1. The External climbing tower cranes is fixed to the ground on a concrete base.
2. The base is then attached to the mast which gives the crane its height.
3. Further the mast is attached to the slewing unit that allows the crane to rotate.
4. On top of the slewing unit there are three main parts which are: the long horizontal jib, shorter counter-jib, and the tower head.
5. The long horizontal jib is the part of the crane that carries the load.
6. The counter-jib carries a counterweight, usually of concrete 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.
9. The hook is located on the long horizontal arm to lift the load which also contains its motor.
