I'm all about "more is better" and all that....
But the shear strength of the factory bolts on that hoist are so much more than the rated design calls for that I might have spent the cash on something a little more rewarding.

The bolts that are used on the lift cylinder (both top and bottom) require the highest shear rating of any other on the hoist. Because of the application, the shear requirements are cut in half (it is exposed to shear effects twice, once on each side of the cylinder ram) so we can double the rated capacity for a safe working load.

Theres always some smart guy just waiting for a chance to armchair engineer yer project.......aint there.

But of course, when using the lift for hoisting personnel, the safety factor is X4 of the calculated SWL.......so I'm not even sure if grade eight is enough for the Powder Puff pick.
