Avoid the phenomenon of overloading of the chain which will seriously affect the safe service life of the lifting sling. Through the above introduction, we must understand that the safety of the entire lifting operation is inseparable from the correct operation, and it is also inseparable from the inspection and maintenance of the various parts of the lifting sling, so when you use the וו and chain It is necessary to do a good job of inspection in time, and pay attention to the precautions in the operation process, so as to effectively ensure that the lifting sling can achieve safe and reliable hoisting work.
