An electric hoist is a special lifting equipment installed on cranes and gantry cranes, featuring compact size, light weight, simple operation, and ease of use. It is used in industrial and mining enterprises, warehouses, ports, and other locations.The electric hoist features a compact structure and uses a worm gear transmission device for those with the motor shaft perpendicular to the drum shaft. Its drawbacks include: large length and width dimensions, bulky structure, low mechanical efficiency, and difficulty in processing. The hydraulic system is dual-controlled, with an overflow regulating valve and a magnetic contact pressure gauge both capable of precise pressure control. The electrical control department uses low-voltage control, enhancing the safety of the system.
