Dampers for the world's longest ropeway

For more than 65 years the Mosdorfer fittings and damping systems have been ensuring the safe and efficient energy transmission worldwide. With the Doppelmayr cooperation a new field of application opened up. Since February 500 Mosdorfer dampers provide for the even safer operation of the world’s longest ropeway in Vietnam.

The key facts of the ropeway are spectacular: It covers a route of around 8 km from the island Phú Quốc across the sea to Hòn Thơm in the South of Vietnam. The towers have a height of up to 264 m. There is still the question: what does the ropeway have in common with a transmission line?

In both areas of application strong vibrations of the ropes are undesirable due to safety aspects. Here the Mosdorfer damping systems are successfully installed. These are directly mounted on the conductor or in this case on the suspension rope and reduce the vibrations of the rope to the minimum. So the dampers do not only increase the operating safety of high-voltage transmission lines, but also the safety of ropeways.

Mosdorfer supported Doppelmayr in a similar application for a facility in Austria, where the Mosdorfer engineers developed an efficient technical solution. As Doppelmayr was confronted with extremely strong vibrations of the suspension rope in Vietnam, the company contacted Mosdorfer again in November 2017.

The goal was the development of a damping system reducing the vibrations of the suspension rope and thereby further increasing the operating safety of the ropeway. “For our engineers the application of the damper was indeed a new one, but not the task itself as the physical background of the rope vibrations at transmission lines and ropeways is the same,” Wolfgang Troppauer, Technical Director at Mosdorfer explains. “The challenge was the tight schedule as the existing products due to their low vibration frequency had to be modulated.”

According to the quality philosophy of both companies the new products had to pass very strict quality controls. Thanks to the technical know-how and long-term experience of the teams at Mosdorfer, also this task was fulfilled successfully. Since February, 500 Mosdorfer dampers ensure the even safer operation of the world’s longest ropeway in Vietnam.
