Glad you think so! Thanks for watching!
So not applicable to overhead lifting but could a person use a grade 80 sling hook in place of a grade 70 slip hook on a grade 70 chain and use the sling hook as one would expect to use a slip hook? Seems like some manufacturers refer to grade 80 and above sling hooks as slip hooks as well but I'm not sure on this subject. I understand that the lowest rating is now the rating of the entire system.
Hi Joe! Thanks for your questions. Yes, absolutely. Somebody could use a grade 80 sling hook in replacement of a grade 70 slip hook. Again, to reiterate, You would not be able to perform overhead lifting with this chain set. The rating of the entire system will be factored by the lowest rated component in the chain setup.
It is unfortunate that sometimes manufacturers refer to their sling hooks as slip hooks. It does create a bit of confusion. That is why it's important to have a competent, qualified person performing overhead lifting. You have to know standards and the equipment you're working with.
I understand that Grades 80, 100, and 120 being the Chain Grades approved for overhead lifting but what about a load that is lifted Vertically but NOT Vertically Overhead?
FOR INSTANCE:. Let's say you are vertically lifting an Engine Block from the shop floor to a height of about your waist or chest high but NOT overhead. Would the Grade Requirements for Overhead lifting only with chain approved for Overhead Lifting still apply?
Chain grades approved for overhead lifting are built to stretch before breaking. They are built to a degree to withstand some sort of accidental overloading. Chain grades not approved for overhead lifting will shatter if accidently overloaded. It is not recommended to use any chain grade for a lift that is not approved for overhead lifting.
I searched this up thinking it was a cool weapon😂
