The Grand Tower 
With a gross floor area of 40.000 m² and a height of 172 m, Grand Tower in Frankfurt is the highest residential tower in Germany. Just a few of the over 400 penthouses and apartments with 41 to 300 m² and concierge service are still for sale. The architecture of Magnus Kaminiarz & Cie with curved balconies or loggias and full panorama windows is airy and modern. Already, the building has reached its full height and it is scheduled to be completed within 2019. At the moment, the focus of the work is on the facade and on the balconies/loggias.
The task
Two WT 420 e.tronic were responsible for the construction of Grand Tower. One of them was already dismantled in December 2018. The other WT 420 e.tronic now has to mount a specialised crane on the roof of the building that is going to be used for the facade and the construction of the balconies/loggias.
The implementation
In order to assemble the specialised crane on the roof at 176 m, the WT 420 e.tronic had to be climbed to 197 m first. The 4×4 m cross frame for the crane was placed on a custom-designed substructure. Likewise, the hoisting winch was special-built and the hoisting load adjustment was tailor-made for this application. The planned tasks required a load torque of 150 mt and 35 m radius. 

The activities of the specialised crane can be watched via the Grand Tower building site web cam.
The finale
When the work of the specialised crane was done in February 2020, its last task was to bring up a WT 35L montage crane that then dismantled the WT 150 e.tronic.  As this was planned beforehand, it was prepared at the factory in such a way, that it could be disassembled in especially small pieces.
