Primarily used for lifting, towing, and handling heavy loads, as well as for tank bottom-up welding, such as the installation and relocation of various large and medium-sized concrete structures, steel structures, and machinery equipment. Suitable for construction companies, industrial plants, civil engineering projects, bridge construction, power, shipbuilding, automotive manufacturing, construction, highways, bridges, metallurgy, mining, slope tunnels, shaft treatment and protection, and other fundamental construction projects.

The components of an electric wire rope hoist include: motor, transmission mechanism, drum, and wire rope. They can be roughly divided into four types based on the different positions of the motor and drum.

(1) Electric hoists with motor shafts perpendicular to the drum shaft use worm gear drives. These have large dimensions in width, are structurally bulky, have low mechanical efficiency, and are difficult to machine. No manufacturers are producing this type of structure anymore.

(2) Electric Hoists with the motor shaft parallel to the drum shaft feature small height and length dimensions. Their drawbacks include a large width dimension, poor grouping, complex manufacturing and assembly, and a large track bend radius.

(3) Electric hoists with motors housed inside the drum feature small length dimensions and a compact structure. Their main drawback is poor motor heat dissipation, poor grouping, and difficulties in inspecting, installing, and maintaining the motor, as well as a complex power supply unit.

(4) Electric hoists with motors mounted externally on the drum feature good grouping capabilities, high degree of generalization, ease of adjusting lifting height, and convenient installation and maintenance. However, the drawback is their large length dimensions.
