Tower cranes are used in the construction of tall buildings. Tower cranes landed on a concrete slab. In the construction of large buildings tower cranes often give the best combination of height and lifting capacity.
The base is then attached to the pole that gives it its full height of the crane. In addition, the mast is attached to the rotary unit that allows the crane to rotate. The peak of the rotation unit, there are three main parts: the long horizontal jib, against short arrow, and the operators cabin.
Luffing tower cranes have been designed to work on high buildings or restricted spaces.
A new development is the ability to equip the tower cranes with a horizontal load path. When the arrow is moved, the lifting mechanism is controlled to ensure that actions horizontal mounting.
Tower crane manufacturer use Liebherr modular concept and have the Electronic Monitor System (EMS) as standard.
