Primarily used for lifting, towing, loading and unloading heavy loads, tank bottom-up welding, such as installation and movement of various large and medium-sized concrete structures, steel structures, and machinery equipment. Suitable for construction companies, industrial and mining enterprises, civil engineering projects and bridge construction, power, shipbuilding, automotive manufacturing, construction, highway, bridge, metallurgy, mining, slope tunneling, shaft treatment and protection, and other basic 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 drive mechanisms. They are large in width, structurally bulky, have low mechanical efficiency, and are difficult to manufacture. No manufacturers are producing this type of structure anymore.
(2) Electric Hoists with motor shafts parallel to the drum shafts have the advantages of small height and length dimensions. However, their disadvantages include large width dimensions, poor divisibility, complex manufacturing and assembly, and a large turning radius for the track.
(3) Electric hoists with motors installed inside the drum offer the advantage of compact length dimensions and a tight 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 outside the drum offer advantages such as good grouping, high degree of standardization, ease of adjusting lifting height, and convenient installation and maintenance. However, their drawback is the large size in length.
