The electric hoist is a special lifting equipment installed on the 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 lifting weight is generally 0.3 to 80 tons, and the lifting height is 3 to 30 meters. It consists of electric motor, transmission mechanism and reel or sprocket. It is divided into electric wire hoist and electric chain hoist. Among them, the electric chain hoist is divided into imported and domestic; the electric wire hoist is divided into single speed and double speed; the miniature electric hoist, winch and multi-function hoist.


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.


The structure and characteristics of the wire rope electric hoist: The machine adopts the electromechanical integration design. When different molds are replaced, the steel wire ropes of different specifications can be pressed, and the control is simple and safe; the inspection, installation and maintenance of the motor are convenient. The main disadvantages are poor motor cooling preconditions, poor grouping, complicated power supply, manufacturing and assembly.


Classification and description of wire rope electric hoist The components of wire rope electric hoist are: motor, commemorative head structure, reel and sprocket. The motor and the reel can be roughly divided into four types according to their mutual position. The pressed steel wire rope has large pulling force, beautiful and fast, and the crimping of a set of steel wire rope can be completed in only a few minutes, which greatly reduces the labor intensity and improves the work efficiency.


The electric hoist with motor mounted on the outside of the reel has the advantages of good grouping, high degree of generalization, easy change of lifting height, and convenient inspection of the device.


Electric hoists are widely used, but there are fewer professionals who can operate electric hoists correctly. It is recommended that you learn more about electric hoists and make better use of various electric hoists in various fields.
