The QPQ Single Hoisting Fixed Hoist is a specialized device for the rapid opening and closing of intake gates in hydraulic and hydroelectric projects. It ensures that, in the event of a failure in the load speed regulation system of the hydraulic turbine-generator set, prior to the occurrence of overspeed or in case of a pipeline burst, the gate can be rapidly closed within 2 minutes, thereby protecting the set and the workshop from potential damage.

The QPQ single-hoist fixed hoist gates are widely used in water conservancy projects such as drainage and irrigation, hydropower stations, river channels, irrigation areas, reservoirs, and so on. The high-pressure sealed box-type gates are an alternative product for hydraulic valves. This product features flexible operation, durability, excellent sealing performance, and high degree of automation, making it an ideal mechanical equipment for water conservancy projects.
