During the use of the hollow pin chain, there will be constant friction between the chainring and the chain wheel, resulting in wear and even deformation, which will lead to a reduction in strength. At last, it will be pulled off as long as it is impacted, especially when the material and manufacturing quality do not meet the standard requirements, it will be easier to break.

Check whether the chain piece of the hollow pin chain is deformed, cracked or corroded. Whether the pin is deformed, rotated or corroded. Whether the drum is cracked, damaged or worn. Whether the joint is loose or deformed. Whether there is abnormal sound or abnormal vibration during work, and whether the chain lubrication degree is good.

If the hollow pin chain is not used properly, it is likely to fall off from the slot of the chain trigger or the power sprocket. There are many reasons, internal and external. The internal cause may be that the length of the conveying chain on both sides of the chainplate is different and the force is unbalanced, or the length of the conveying chain on both sides of the chain plate is different and the force is unbalanced. External causes, it is possible that the hollow pin chain is seriously worn or mixed with impurities, or the head is not installed properly, and the verticality of the hollow pin chain and the head does not meet the requirements. So if you want to solve this problem, you'd better find out the reason first.
