As far as I understand jack stand ratings, the stated capacity is "per pair"
unless otherwise specifically stated. e.g. If I buy a set of jack stands rated
at 3 tons, they are typically rated for 1.5 tons each with the weight evenly
distributed. (A few brands are rated individually, but not most, AFAICT)
So why is each stand marked with it's own 3 ton label without any warning
that the rating is for the pair? It's only in the manual that you will
find that information.
A 3 ton floor jack is rated and labeled as 3 tons but a single 3 ton jack
stand is rated at 1.5 tons yet labeled as 3 tons. That just seems unsafe.
I also understand that jack stands are supposed to be tested to 1.5 times
their rated capacity, so a single "3 ton" jack stand should support 4500 lbs.
6000/2 x 1.5 = 4500
That's more than enough to support a corner of any of my vehicles, so I'm
not concerned that 3 tons isn't enough capacity for my uses, just annoyed.
