Climbing crane

A WOLFF 7532.16 outside climbing crane during the construction of the Roche Tower

A climbing crane is a tower crane that, after basic assembly, can be erected to high hook heights by inserting additional segments, so-called tower sections, with the help of hydraulic climbing devices. Climbing cranes are used wherever large hook heights, large projections or large load capacities are required, especially when building high-rise buildings , towers or chimneys . In addition to stationary cranes, rail-mounted cranes can also be used.

A distinction is made between inside and outside climbing cranes. As a rule, cranes climb the outside of the building to reach a greater hook height. The dismantling of the climbing crane is carried out according to the same principle in reverse order up to the basic assembly. The indoor climbing crane is usually installed in the elevator shaft of the building. Because of the more favorable arrangement in the building, a smaller type of crane can often be used than for the crane climbing outside. The disadvantage of the climbing crane is that it is difficult to transport and assemble. A further distinction is made between adjustable and luffing booms, which can reach lifting heights that are above the boom's articulation point. A two-part articulated boom is used to combine the advantages of both types of boom. In the horizontal position this has the great reach of the trolley jib , in the bent position it has the greater hook height.

The installation of climbing cranes via the construction site delivered assemblies usually with a local mobile crane to be mounted on the basic hook height. Then the climbing crane can automatically grow to the desired height or with the construction progress.

In 2017, a wind turbine manufacturer in Eemshaven, the Netherlands, tested a climbing crane for the first time to erect a wind turbine.
