Usually we buy back the CD1, MD1 wire rope hoist height difference in the lifting mechanism is different, what is the lifting mechanism, the specific difference, Guangzhou pigeon lifting for you to specify. The lifting mechanism of the wire rope electric hoist is driven by the hoist motor through the coupling through the hollow shaft of the reducer to rotate the drum, so that the wire rope wound on the drum drives the hook device to rise or fall. When lifting height H=6m, a claw coupling is used to connect the motor shaft and the input shaft of the reducer. When H≥9m, add intermediate shaft and rigid coupling. When H ≥ 18m, the support frame is used to strengthen the rigidity of the intermediate shaft to ensure smooth rotation.
