The electric hoist is a special lifting equipment installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places.
The electric hoist is compact, and the electric hoist whose motor axis is perpendicular to the spool axis adopts a worm gear transmission. The disadvantages are: large length, large size in width, stupid structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual control, and the overflow control valve and magnetic contact pressure gauge can precisely control the pressure. The electrical control department uses low voltage control to increase the safety of the dominant system.
