Two winches for a safe construction

For the construction of a hydro power plant in the Austrian Alps GANTNER designed and produced a heavy duty winch.

The rope winch has a pulling capacity of 600 kN (up to 800 kN possible) in order to lower large tube shots with a diameter of approx. 6 m into a drift shaft where they are welded afterwards.

The shaft winch can transport tubes with a speed of 60 m per minute with its electro-hydraulic drive. It has a 48 mm thick rope with a length of almost 1,700 m. The winch is powered by an electro-hydraulic power unit with 500 kW power.
The heavy load requires respective safety features. In addition to the safety brakes which are acting directly on the cable drum with large disc brakes, the braking system has two multiple-disc brakes.

Together with the heavy duty winch GANTNER delivered a second shaft winch which is applied for the same shaft. It is a smaller service winch or winch for manpower transport. This rope winch is used to get construction workers on a platform in the inclined shaft where they install the tubes and perform service and maintenance work.
