Primarily used for lifting, towing, and loading heavy objects, oil tank bottom-up welding, as well as the installation and relocation of various large and medium-sized concrete, steel structures, and mechanical equipment. Suitable for construction companies, industrial and mining enterprises, civil engineering projects and bridge construction, electricity, 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. They have large dimensions in width, are 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 feature small height and length dimensions for the wire rope hoist. However, they have larger width dimensions, poor divisibility, and complex manufacturing and assembly processes. The track has a large turning radius.

(3) Electric hoists with motors housed within the drum feature a compact length dimension. Their primary drawback is poor motor cooling, poor grouping, and不便 for checking, installation, and maintenance of the motor, along with 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 dimensions.
