The QPQ Single Hoist Fixed Hoist Closure Machine is a specialized device for rapidly opening and closing the intake gates in hydropower and water conservancy projects. It ensures that, in the event of a failure in the load speed regulation system of the turbine-generator set, prior to the occurrence of overspeed or in the event of a burst in the pressure pipeline, the gates can be quickly closed within 2 minutes through either automatic or manual control, thereby achieving the purpose of protecting the set and the factory building from danger.

QPQ Single Hoisting Fixed Hoist is widely used in irrigation and drainage, hydropower stations, rivers, irrigation districts, reservoirs, and other water conservancy projects. The high-pressure sealed box-type sluice gate is a substitute product for hydraulic valves. This product features flexible operation, durability, good sealing performance, and high degree of automation, making it an ideal mechanical equipment for water conservancy projects.
