It is easy to operate and widely used. Explosion-proof chain hoist suddenly cannot be lowered during use. What should I do? What is the reason for this situation?
1. Excessive force during operation of the explosion-proof chain hoist causes the chain to become stuck, which prevents the chain hoist from being lowered, and the chain can be continued to be used after resetting the chain.
2. The internal parts of the explosion-proof chain hoist are damaged, which causes the internal parts to run smoothly and cannot be lowered.
3. Debris enters into the gear, resulting in excessive resistance and cannot be lowered.
4. Friction is increased due to the decrease of lubricating oil, and the lowering operation cannot be performed.
5. The friction plate is malfunctioning, which prevents the explosion-proof chain hoist from descending.
The above is the reason why the explosion-proof chain hoist cannot be lowered. Do you know? If you have any other questions, please feel free to contact our staff for consultation.
