About the classification of wire rope electric hoist

                                               
The components of  Wire Rope Electric Hoist are: motor, transmission mechanism, drum and wire rope. The motor and reel can be divided into four types according to their different positions.
(1) The electric hoist whose motor axis is perpendicular to the reel axis uses a worm gear transmission, which has a large width, a heavy structure, a low mechanical efficiency, and a difficult processing. There are no manufacturers producing products of this type.
(2) The electric hoist whose motor axis is parallel to the drum axis has the advantages of small height and length. Its disadvantages are large width, grouping, and complicated manufacturing and assembly. The turning radius of the track 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 motor heat dissipation conditions, poor grouping, inconvenient inspection, installation, and maintenance of the motor, and complicated power supply devices.
(4) The electric hoist with the motor installed outside the drum has the advantages of good grouping, high degree of generalization, easy lifting height change, and convenient installation and maintenance. Its disadvantages are: the length is large.
