The 1st section of the Parsenn cable car Davos - Höhenweg was extensively renovated in 2002. It serves the Parsenn ski area, the military and the Institute for Snow and Avalanche Research SLF as the only feeder lift and to a certain extent represents the lifeblood of the entire Parsenn area. In order to ensure the continued availability of the installation, it is essential that the control and drive systems are brought up to the latest state of the art. In addition, maintenance work is required on the track, the vehicles and the safety systems. A reasonable time frame for this work, which offers certainty in planning and execution, is essential. However, this does not allow for guest operations in summer 2025.
