The fixed winch hoist is a winding device used to operate fixed gates, driving the gate to lift or lower through a wire rope pulley system, suitable for large-span gate scenarios.
Structural Features
It employs a wire rope pulley system for transmission, featuring a compact structure and stable operation, capable of meeting the hoisting requirements of large-span gates. It is typically equipped with a speed-limiting device that restricts the descent speed to within 5 m/min when the gate approaches the sill, avoiding violent collisions and component damage.
Function and Application
Primarily used for controlling fixed gates in hydropower stations, reservoirs, and other hydraulic facilities, it offers both local and remote operation capabilities. The remote operation system uses DC power to control emergency rapid gate closure, ensuring emergency shutdown can be achieved even in the absence of AC power.
Selection Considerations
Selection should be based on parameters such as gate size, hoisting force, and travel distance. During installation, verticality and horizontal deviation must be calibrated to ensure transmission efficiency and safety.
