Short project description:

We upgraded the entire control system for the shaft access installation of the Pfänder Tunnel on behalf of ASFINAG Alpenstrassen GmbH. The original machines dated back to approx. 1980 and had not been upgraded since.

The shaft access system serves to inspect the air supply and ventilation shafts in the tunnel and to perform rescue operations in the tunnel during emergencies.

The shaft access installations are 320 or 260m long and operate at a speed of 0.5m/s. Speed monitoring systems and safety brakes are handled by the safety control system.

The project was implemented over a period of approximately 4 months (January – April).
