To what extent can the chain hoist hook be scrapped?
Lifting machinery has a certain service life, in addition to its overall parts, parts also have a life limit. SHIFT chain hoist hook, as a direct force component, is especially easy to be damaged and scrapped.
Let's take a look at the scrapping standards of hoist hooks:
We all know that the hook itself is live and is used to hang heavy objects. If its opening is more than 15%, it needs to be replaced with a new hook, otherwise it is easy to cause falling objects.
Secondly, since the hook directly bears the hanging force of the lifting object, distortion and cracks will appear over time. There is a standard for the twist of the hook, once the twist exceeds 10,
That is, the scrapping standard is reached; for the hook, once a crack occurs, the stability and safety of its lifting operation will be reduced, and it must be replaced immediately.
