No, but I can't imagine any bolt bigger than 1/4" grade 3 that would

have a tensile strength several times the weight of any BP mill, even
multiplied by the cantilever.


Of course you're right, but I have this thing about "safety factor" with

Key points:

- It's not "overhead lifting", it is simple lifting.

- Lift it a couple inches, then pull the trailer out from under it, then
lower it to an inch or two above the ground before any horizontal
movement.
