    What are the reasons why the explosion-proof chain hoist suddenly cannot move when used?


Description: Explosion-proof hoist is divided into two categories according to the driving method: one is an explosion-proof chain hoist, and the other is an explosion-proof electric hoist; the explosion-proof electric hoist is lifted by electric drive, and the explosion-proof hoist is The human pulls the hand zipper to transfer the sprocket and drive the lifting chain to lift the heavy object. Today, we will introduce the reasons why the hand chain suddenly cannot be pulled when using the explosion-proof chain hoist. How should we solve it?
Explosion-proof hoists are divided into two categories according to the driving method: one is an explosion-proof chain hoist , and the other is an explosion-proof electric chain hoist ; the explosion-proof electric chain hoist is lifted by electric power, and the explosion-proof chain hoist is pulled by human The hand zipper bar transfers the sprocket and drives the lifting chain to carry the heavy load. Today we will introduce the reasons why the hand chain cannot be pulled suddenly when using the explosion-proof chain hoist. We should How to solve?
1. If the hand zipper bar of the explosion-proof chain hoist cannot be pulled, it may be due to the problem of the card chain. If the hand zipper bar is caught in the middle of the cover and the sprocket, we cannot pull the hand zipper bar at this time. ;
Explosion-proof chain hoist
2. When we use an explosion-proof chain hoist, if there is a foreign object falling inside the chain hoist housing, it will easily cause a jamming phenomenon;
3. If the hand zipper bar of the explosion-proof chain hoist cannot be pulled, it may be because of a problem with the hand zipper wheel. If the hand zipper wheel and the hand zipper bar have problems in the meshing process, we cannot pull the hand zipper at this time. article;
4. If there is a problem with the transmission mechanism of the explosion-proof chain hoist, which causes them to complete the normal rotation function, so we cannot operate the chain hoist during the process of pulling the hand zipper bar;
If you are using an explosion-proof chain hoist , the hand zipper of the chain explosion-proof hoist suddenly cannot be pulled, please do not violently pull it. If you pull the chain vigorously, it is likely to break it, and this will not solve the card chain. Problem, so we must first remove the heavy object, and then open the cover of the explosion-proof chain hoist to check the abnormal conditions of the internal parts. If the chain is stuck, please smooth it. If there is a problem with the chain, please replace it with a new one. The model of the chain, after troubleshooting one by one and repair it, put it into use.
