Structure: Shopping Centre Cologne-Hürth Mobile suspended ladder with sliding platform

The pyramid access equipment is anchored in the centre of the roof structure with a king journal, so that only one circumferential rail is required. The required length compensation for going around the corners shall be ensured with a sliding arrangement installed above the central rotary structure. Easy operation is ensured with a mechanical manual operating system on the rail carriage. An internal cleaning installation was also installed on the glass roof pyramid, and further, another four access equipments were installed inside and outside on ridge roofs on the "Hürth Shopping Centre".
