Now most of the winch hoist is powered by the motor, and the small and medium-sized capacity specifications can be equipped with hand devices, which is convenient for manually opening and closing the gate at any time.
The hoist hoist is composed of a motor, a coupling, a drive shaft, a reducer, a brake, an open gear, a drum part, a master controller, a frame, and a pulley. The wire rope of the hoisting machine passes through the pulley, the fixed pulley and the balance wheel, and the two ends are fixed to the end of the spiral groove of the left and right of the drum (or the middle part) with the pressure plate respectively. When working, the power of the motor is driven by the coupling, the reducer and the open gear, and the wire rope is drawn in or released in the spiral groove, so that the gate can be opened and closed. The master controller can control the upper and lower limit positions of the gate, and the brake can keep the gate in any position required.
This machine is a special machinery for water conservancy projects, widely used in the opening and closing of water conservancy project gates, is a supporting machinery for farmland irrigation, aquaculture, agricultural economic development zones, sewage treatment plants, water conservancy power stations, reservoirs (sluice, dam, tunnel, pipeline) and other inlet and exit sluice gates, mountain, plain, no electricity areas can be used. According to the design requirements of the user’s water conservancy project, it can also produce double lifting hoist.
