The arc gate hoist is a type of hoisting equipment used to operate radial gates, primarily employed in hydraulic and hydroelectric engineering for gate control. It features a compact structure, high hoisting capacity, and flexible travel.
Structural Composition
It mainly consists of components such as the motor, reducer, drum, steel wire rope, pulley block, and frame. Through the reducer and pulley block, torque amplification is achieved, making it suitable for operating large-sized gates.
Functional Features
High Hoisting Capacity: By combining the reducer and pulley block, a significant gate-opening force can be obtained, making it suitable for large openings or high-head gates.
Flexible Travel: The direction of force on the steel wire rope can be adjusted, and with the use of deflection pulleys, it can adapt to gate opening requirements at different angles.
Synchronized Control: The double-lifting point design ensures synchronous operation on both sides, guaranteeing smooth opening and closing of the radial gate.
Safety Configurations: Equipped with a speed-limiting device (speed ≤ 5 m/min when approaching the sill) and a braking system to prevent gate falling or collision.
Application Scenarios
Primarily used for controlling radial gates in hydraulic and hydroelectric engineering, such as emergency gates or inspection gates in reservoirs and hydropower stations. It also features rapid closing functionality to respond to emergencies.
Maintenance Considerations
Regular inspections of the steel wire rope arrangement, braking system, and lubrication are necessary to avoid failures caused by rust or jamming.
