Double Lifting Screw Hoist Factory

The double-lift screw hoist is a mechanical device used in hydraulic engineering, which drives the gate to lift or lower through the rotation of a screw. It features a simple structure and convenient operation, and is widely applied in reservoirs, rivers, channels, and other locations.
Structure and Working Principle
The double-lift screw hoist mainly consists of a motor, screw, transmission device, etc. The motor drives the screw to rotate, which in turn moves the gate up or down to achieve opening or closing. Its design employs a double-lift structure, offering higher stability and load-bearing capacity compared to traditional single-lift models, making it suitable for complex working conditions with large flow rates and high pressure.
Installation and Maintenance
During installation, it is essential to ensure a stable foundation, with the screw axis perpendicular to the horizontal plane of the gate platform and fully aligned with the gate lifting hole. Before operation, check the lubrication condition, bolt tightness, and power circuit connections. The initial run requires no-load and load tests to ensure smooth operation. Routine maintenance involves regularly cleaning metal debris, replenishing lubricating oil, and inspecting the condition of electrical components.
Application Scenarios
It is primarily used in hydraulic engineering projects such as reservoir flood control regulation, river management, farmland irrigation, and urban drainage. By precisely controlling water flow, it enables water level management, ensuring flood control safety and efficient utilization of water resources.
