Obervermuntwerk II

Heavy-duty cable crane system with 20 to installed in Vorarlberg, Austria.

  • As part of the construction of a pumped-storage power plant of the Vorarlberger Illwerke, a heavy-duty cable crane system was installed and operated in the Austrian Montafon from July 2014 to October 2018.

    The large construction site for the construction of the hydro power plant was located at an altitude of over 1,700 m above sea level and was accessible via the “Silvretta Hochalpenstraße”, a high alpine road. Due to the closure of the road caused by heavy snowfall in the winter months, the construction site could not be reached by trucks, which is why LCS installed a cable crane system with a payload of 20 to and operated it during the four-year construction period.

    The system with its innovative tower construction (with two retaining ropes that reached from the bottom to the top station) had a considerable length of 2,640 m. The cable crane system was equipped with a circular drive with two 400 kW (total 800 kW) strong electro-hydraulic drives and was therefore able to transport loads with a speed of up to 6 m/s.
