Gates

ANDRITZ HYDRO supplies any type of high-pressure gates, such as fixed wheel gates, sliding gates, radial gates, and caterpillar gates, as well as gates for ship locks, such as miter gates or sector gates.

Dams for hydropower plants have to meet the 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. Besides hydro-mechanical equipment for hydropower plants, ANDRITZ HYDRO additionally offers gates for ship locks, such as miter gates or sector gates.

For controlled flood discharge, ANDRITZ HYDRO supplies spillway gates, normally as radial or fixed wheel gates. For low head or run-of-river power plants, the product and service scope includes all types of hydro-mechanical equipment for weirs, and for power house inlet and outlet structures.

ANDRITZ HYDRO also supplies trash racks, raking machines, and cranes, as well as stoplogs, lifting beams, and valves.

In line with today’s technology, the gates are operated by hydraulic hoisting systems, but mechanical rope or chain hoists can also be provided. For operation and control of the gates, ANDRITZ HYDRO uses hardware from internationally renowned manufacturers, while the necessary software is developed by ANDRITZ engineers, who are also responsible for testing and commissioning of the supplies.

Project highlights:

  • Bottom outlet gates with an operating head of 189 m for Mica Dam, Canada
  • Sliding gates for a new bottom outlet operated under 190 m water head for the Mauvoisin Dam, Switzerland
  • Weir radial gates with flaps and a span of 24 m for the hydropower plants on the river Danube, Austria

Research and hydraulic investigations are very important topics for development of gates. Based on numerous model studies for high-head and low-head gates, new insights into hydro-mechanical behavior could be gained, enabling ANDRITZ HYDRO to enhance the operational safety of these structures.
