The working principle of the electric winch is to convert electrical energy into mechanical energy through the motor, that is, the rotor output of the motor is rotated, and after the V-belt, shaft and gear are decelerated, the drum is driven to rotate. The drum winds the steel wire rope and passes the pulley unit to lift or drop the load on the crane hook, transform the mechanical energy into mechanical work, and complete the vertical transportation and loading of the load. The structure of the electric hoist is composed of a motor, a coupling, a brake, a gear box and a drum, which are installed on the frame together.
For electric hoisting machines with large lifting height, large loading and unloading capacity, and busy working conditions, they require good speed regulation performance, especially the empty hook can be lowered quickly. For installation or sensitive materials, it should be able to descend at a slight movement speed.
The winches include JK fast winches and JM slow winches, which can only be used on the ground. It uses electric motors as power, passes elastic couplings, three-stage closed gear reducers, toothed couplings drive drums, and adopts electromagnetic system.
This product has high versatility, compact structure, small size, light weight, heavy lifting, and convenient use and transfer. It is widely used in materials lifting or leveling of construction, water conservancy engineering, forestry, mining, docks, etc., and can also be used for modern electrical control Supporting equipment for automatic operation line.
