The components of the electric hoist are motor, transmission, reel, and sprocket.

The motor and the reel can be roughly divided into four types according to their mutual position:

(1) The electric hoist whose motor axis is perpendicular to the reel axis adopts the worm gear transmission. The width is large, the structure is heavy, the mechanical efficiency is low, and the processing is difficult. There is no manufacturer to produce this type of product.

(2) The electric hoist whose motor axis is parallel to the spool axis has the advantages of small height and length dimension. The disadvantages are the large width, grouping, complicated manufacturing and assembly, and large turning radius.

(3) The electric hoist of the motor mounted in the reel has the advantages of small length and compact structure. The main disadvantages are poor heat dissipation conditions of the motor, poor grouping, inconvenient inspection, installation and maintenance of the motor, and complicated power supply devices.

(4) The electric hoist mounted on the outside of the reel has the advantages of good grouping, a high degree of generalization, easy change of lifting height, and convenient installation and maintenance. The disadvantage is that the length is large.
