Diesel Hydraulic Power Unit for Emergency Cable Car Drive - Grünberg

As part of the modernisation of the Grünberg cable car in Gmunden, a complete overhaul of the main and emergency drives was undertaken.

Project description:

• Two large cabins each with a capacity of 60+1 passengers
• Operating (incline) length: 2025.46 m
• Height differential: 550.89 m
• Diesel engine incl. frame with 129 kW drive power
• After starting, automatic ramp-up of the diesel engine from idle to full operating speed
• DANFOSS POWER SOLUTIONS closed circuit, high pressure variable displacement axial piston pump
  (controlled by a SIEMENS control unit in the driver's cab)
• Hydraulic joystick for emergency operation in the machine room
• Open brake circuit pump (as soon as the operating speed of the diesel engine increases due to a lack of
  braking power, the system is automatically and gently brought to a halt by hydraulic means using a proportional pressure limiting valve)
• REGGIANA RIDUTTORI planetary gearhead in cable car design and DANFOSS POWER SOLUTIONS axial piston fixed displacement motor (engaged in the cable car sprocket during emergency operation)
• The new Grünberg cable car entered public operation on 14/06/2014
