Since the introduction, promotion, and use of wire rope electric hoists in various fields in the country today, our country’s lifting industry technology level and construction civilization have greatly improved. Wire rope electric hoist is a kind of small lifting equipment. The wire rope electric hoist has the advantages of compact structure, light weight, small volume, strong universal parts, and easy operation. And today nucleon crane's engineer will talk about the advantages and disadvantages of wire rope electric hoist.

Advantages and Disadvantages of Wire Rope Electric Hoist:

The components of the wire rope electric hoist are: motor, transmission mechanism, reel and wire rope. The motor and reel can be roughly divided into four types depending on their position. 

structure of wire rope electric hoist

1. The electric hoist with the axis of the motor perpendicular to the axis of the reel adopts a worm gear. The width is large in size, heavy in structure, low in mechanical efficiency, and difficult to process. There are no manufacturers to produce this type of structure.

2. The electric hoist with the axis of the motor parallel to the axis of the drum has the advantage of small height and length. The disadvantages are large width dimensions, grouping, and complex manufacturing and assembly. Large turning radius.

3, electric motor mounted on the drum inside the electric hoist, its advantages are small size, compact structure. Its main disadvantages are poor thermal conditions of the motor, poor grouping performance, inconvenience in checking, installing, and maintaining the motor, and complex power supply devices.

4. The electric hoist mounted on the outside of the drum has the advantages of good grouping, high degree of generalization, easy to change the lifting height, and easy installation and overhaul. The disadvantages are: large size.
