Feel free to move this question to a more appropriate forum, i just couldn't think of where else to put it as there is no rigging forum.
So im looking at chain to replace the steel cable which currently supports the raceways and battens on our electrics (5 of them). i think im gonna use 3/8 grade 80 chain(7100# WWL) (way stronger than the 1/8 the aircraft cable(1700# break strength) that's up there now and was installed by a local company, without thimbles in the swages mind u).
But i was wondering, what is the primary reason that only grade 80 and above is rated for overhead lifting and hanging. for the sake of argument why couldn't i use a 1/2" grade 43 (9,200# WWL).
Id also like your opinion on not having thimbles in the steel cables. frankly i don't like it.
Thanks
