Lifting strand breaks causes and preventive measures
"Why would lifting chain breaking it? Lifting chain, quality is good and can withstand gravity is also very large, but constant fracture occurred phenomenon", "Why lifting chain will have broken it? Produce fracture What causes it? "Online there are some people raised Questions, here we strand breaks causes and prevention of lifting lifting strand measures which?
1 lifting strand breaks reasons:

The reason is simply caused by breaking the chain of natural wear and tear, excessive wear. Severe wear on the chain when the chain should take into account the ability of the pressure to go use, but if it is natural wear and tear, in use as long as actively take preventive measures to reduce and prevent the incidence of failure had  This would greatly reduce the rate.

(2) Measures to prevent lifting strand breaks:

Hoist equipment tightness inappropriate; chain side wear; shaft bent, the chain deflection; badly worn chain continued use; sprocket wear exceeds the allowable limit; cotter pin bush roller chain wear off off, or connector clamp opening direction hold against; hook chain badly worn or installed backwards, can cause load chain off the chain, break and release. To prevent this failure generates, you must make the same drive line in the same plane of rotation of the sprocket inside; always check the chain wear, timely repair and replacement; always check the load chain case cotter pin connector and replace if necessary; straightening curved   Shaft, rotate the chain does not exceed the allowable amount of rocking; correctly adjust tightness of the chain; timely repair and replacement over the sprocket wear limits,  properly adjusted safety clutch; timely lubricate the drive chain.
