The QPQ Single-Chain Hoist Gate is a specialized device for quickly opening and closing intake gates in hydraulic and water conservancy projects. It is used to close the gates within 2 minutes, either through automatic or manual control, in case the hydropower generating set fails due to the load speed control system, or before a turbine runaway occurs or a pipeline rupture accident happens, to ensure the safety of the equipment and the powerhouse.

The QPQ single suspended winch for opening and closing gates is widely used in irrigation and drainage projects, hydropower stations, rivers, irrigation areas, reservoirs, and other hydraulic engineering applications. The high-pressure sealed box type sluice gate is a substitute product for hydraulic valves. This product features flexible operation, durability, excellent sealing performance, and a high degree of automation, making it the ideal mechanical equipment for hydraulic engineering.
