How to change the broken hoist bearing?
Sep 11, 2018

      The most important part of the electric hoist is the motor. The most important part of the hand chain hoist is the "bearing" which is not conspicuous, but can not be ignored. The main role of bearings is to support, it mainly depends on rolling contact between components to support transmission components, long-term use of hand chain block will cause bearing damage, then how to replace bearing damage?

      The first step is to use a round stick to insert the bore of the bearing in the head of the hand-pulled hoist. The bearing in the head of the hand-pulled hoist is moved to the groove direction on the bearing seat of the hand-pulled hoist by stages, and then the hand-pulled hoist bearing is removed and replaced.

      Secondly, loosen the bolt for fixing the bearing in the head of the hand-pulling hoist by hand, and remove the bearing in the head of the hand-pulling hoist together with the bearing seat of the hand-pulling hoist.

      Finally, loosen the inner hexagonal screw of the hand-pull-hoist bearing, if the hand-pull-hoist bearing with eccentric sleeve, then loosen the inner hexagonal screw, reverse the rotation direction of the head shaft of the hand-pull-hoist to send the eccentric sleeve.

      Shanghai Hugong here reminds users that when disassembling and assembling the hand-pulled hoist, it must be done by people familiar with the equipment to prevent the damage of the whole machine caused by disassembling and assembling the hand-pulled hoist at will without understanding the performance principle of the hand-pulled hoist.
