Mechanical Parts:
motor, transmission mechanism, reel and wire rope. The motor and the reel can be roughly divided into four types based on the different positions of each other.
(1) The electric hoist whose motor axis is perpendicular to the axis of the drum adopts worm gear transmission, which is large in width, heavy in structure, low in mechanical efficiency, and difficult to process. No manufacturer produces products of this type of structure anymore. Wire rope electric hoist
(2) The electric hoist with the motor axis parallel to the drum axis has the advantage of small height and length.Its disadvantages are large width, grouping, and complicated manufacturing and assembly. The track turning radius is large.
(3)The electric hoist with the motor installed in the drum has the advantages of small length and compact structure. Its 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 with the motor mounted on the outside of the drum has the advantages of good grouping, high degree of generalization, easy to change the lifting height, and convenient installation and maintenance. The disadvantage is: the length is large.
