Primarily used for lifting, towing, and handling heavy loads, tank inversion welding, as well as the installation and relocation of various large and medium-sized concrete, steel structures, and machinery equipment. Suitable for construction companies, industrial and mining enterprises, civil engineering and bridge construction projects, 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, which are large in width, structurally bulky, have low mechanical efficiency, and are difficult to manufacture. No manufacturers are producing products with this type of structure anymore.

(2) Electric Hoists with the motor shaft parallel to the drum shaft have the advantage of small height and length dimensions. However, they have the drawback of large width dimensions, poor divisibility, and complex manufacturing and assembly. The track bend radius is large.

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

(4) Electric hoists with motors mounted on the drum outside offer advantages such as good grouping, high degree of standardization, easy adjustment of lifting height, and convenient installation and maintenance. However, their drawback is the large length dimension.
