Electric hoist is a kind of special lifting equipment, which is installed on overhead crane and gantry crane. 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 has a compact structure, and the electric hoist whose motor axis is perpendicular to the reel axis adopts a worm gear transmission. The disadvantages are: large length, large width, clumsy structure, low mechanical efficiency, and difficult processing.
The hydraulic system is dual-controlled, and the overflow regulating valve and the magnetic contact pressure gauge can precisely control the pressure. The electrical control department adopts low voltage control, which increases the safety of the control system.
The components of the electric hoist are: motor, transmission mechanism, reel and sprocket.
Electric hoists are mainly divided into: chain electric hoists, wire rope electric hoists (explosion-proof hoists), anti-corrosion electric hoists, double drum electric hoists, hoists, miniature electric hoists, group crane electric hoists, and multi-functional hoists.
