Primarily used for lifting, dragging, loading, and unloading heavy loads, tank inversion welding, such as the installation and movement of various large and medium-sized concrete, steel structures, and machinery equipment. Suitable for construction companies, industrial plants, civil engineering projects, and bridge construction, as well as for the construction equipment in power, shipbuilding, automotive manufacturing, construction, roads, bridges, metallurgy, mining, slope tunnels, well shaft management, and protective construction.
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 shafts 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 housed within the drum offer the advantage of compact size and structure. However, their main drawback is poor motor cooling, poor grouping, and inconvenience for motor inspection, installation, and maintenance, as well as a complex power supply unit.
(4) Electric Hoists with motors mounted outside the drum offer advantages such as good divisibility, high degree of standardization, easy adjustment of lifting height, and convenient installation and maintenance. The drawback is the larger overall length size.
