20t heavy duty electrical hoists

Brief introduction of 20t heavy duty electrical hoists :

CD and MD electric hoists are mainly composed of three parts:lifting mechanism,travelling mechanism,electrical parts.

Basic parameters:

1.Capacity:1-20t
2.Lifting height:6-18m
3.Speed:single or dual
4.Voltage:220/380/400/415v
5.Pendent control or wireless

This type wire rope electric hoist is improved from CD and MD model electric hoist,the working conditions are same as CD and MD model,it increases more lifting room and can save construction cost of workshop.This type wire rope hoists could be installed on the straight or curved I type steel beam of single girder overhead cranes/gantry crane, jib crane to lift heavy objects,the wire rope electric hoists are widely used in industrial and ore enterprises,railway,wharf and warehouses.
