Electric hoist is a kind of special lifting equipment, installed on overhead cranes and gantry cranes. The electric hoist has the characteristics of small size, lightweight, 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 axis of the drum adopts a worm gear transmission device. Its disadvantages are large length, large width, rough structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the pressure can be precisely controlled by the overflow regulating valve and the magnetic contact pressure gauge. The electrical control department adopts low voltage control to increase the safety of the control system.
