Arc gate type winch hoist

The arc gate hoist winch is a type of winch-operated hoisting equipment used for operating radial gates, primarily employed in hydraulic and hydropower engineering for gate control. It features a compact structure, high hoisting capacity, and flexible travel range.
Structural Composition
It mainly consists of components such as the motor, reducer, drum, steel wire rope, pulley block, and frame. Torque amplification is achieved through the reducer and pulley block, making it suitable for operating large-sized gates.
Functional Features
High Hoisting Capacity: Through the combination of the reducer and pulley block, a significant gate-opening force can be achieved, making it suitable for large openings or high-head gates.
Flexible Travel Range: 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 various angles.
Synchronized Control: A double-lifting-point design ensures synchronous operation on both sides, guaranteeing smooth opening and closing of radial gates.
Safety Configurations: Equipped with speed-limiting devices (speed ≤5m/min when approaching the sill) and braking systems to prevent gate falling or collisions.
Application Scenarios
Primarily used for controlling radial gates in hydraulic and hydropower engineering, such as emergency gates or inspection gates in reservoirs and hydropower stations. It also features rapid closing functionality to respond to unexpected incidents.
Maintenance Considerations
Regular inspections of steel wire rope alignment, braking systems, and lubrication conditions are necessary to prevent malfunctions caused by rust or jamming.
