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.
