Dams for hydropower plants have to meet most stringent safety requirements. ANDRITZ HYDRO supplies any type of high pressure gates, such as fixed wheel gates, sliding gates, radial gates and caterpillar gates. These gates are used for power intakes, bottom outlets or river diversion works.

As outstanding projects may be mentioned the bottom outlet gates for Mica Dam / Canada with 189 m operating head and the recently awarded sliding gates for a new bottom outlet for the Mauvoisin Dam / Switzerland, which are to be operated under 190 m waterhead. For controlled flood discharge ANDRITZ HYDRO also supplies spillway gates, normally as radial or fixed wheel gates. For low head or run-off-the-river power plants ANDRITZ HYDRO supplies all kinds of hydromechanical equipment for weirs and power house inlet and outlet structures.

ANDRITZ HYDRO also supplies trashracks, raking machines and cranes.
Following today’s technology, our gates are operated by hydraulic hoisting systems, but also mechanical rope or chain hoists can be provided. For operation and control of the gates, ANDRITZ HYDRO uses hardware by internationally renowned manufactures, while the necessary software is developed by our own engineers, who are also responsible for the testing and commissioning of our supplies.
Among the many references, the weir gates for the hydropower plants on the river Danube / Austria may be mentioned; these radial gates with flaps are with a span of 24 m among the largest in the world.
Beside hydromechanical equipment for hydropower plants,ANDRITZ HYDRO offers also gates for ship locks, such as mitre gates or sector gates.
Also for gates, research and hydraulic investigations are keys for successful business. On the basis of numerous model studies for high-head and low-head gates executed by ANDRITZ HYDRO, new insights into hydromechanical behaviour could be gained, enabling us to enhance the operational safety of these structures.
