Arc Gate Hoist Winch Factory

The radial gate hoist is specialized equipment used in hydraulic engineering to operate radial gates, with its core function being the lifting and lowering control of the gate through a wire rope pulley system.
Core Components and Functions
‌Drive System‌: Includes an electric motor, reducer, drum, and wire rope pulley system, supporting rapid opening and closing (e.g., emergency gates must close within 2 minutes).
‌Speed Limiting Device‌: Ensures the gate speed does not exceed 5 m/min when approaching the sill to avoid collision damage.
‌Dual Lifting Point Design‌: Utilizes a synchronization shaft for dual drive, suitable for large-span gates to prevent jamming.
Technical Parameters and Engineering Applications
‌Capacity Range‌: The maximum domestic capacity reaches 2×4000 kN (Tianshengqiao Hydropower Station), with a lifting height of up to 125 m.
‌Applicable Scenarios‌: Widely used in flood discharge outlets, deep outlets, and particularly suitable for emergency protection scenarios requiring rapid gate closure.
