Structure: S- and long-distance train platform of Berlin Friedrichstraße |
The reconstructed glass roof of the Friedrichstraße – Berlin – station is cleaned with the help of a total of 6 maintenance platforms. Each of the 150-metre sections is traversed using electrical drives over a busbar with current collector. Due to the geometry of the station hall and the differing distances between the rails, we developed a curved structure to enable transport over the entire section under differing conditions, using a sliding arrangement in the supporting structure. For reaching the glass surfaces in the roof ridge area, mobile ladder towers telescoped with hand winches were used. Additional access equipments were also supplied at the S-station Friedrichstraße for the maintenance and cleaning of the longitudinal facades and the glass-paned gables. |
