I guess that is the question: How much weight? I guess like to be
able
to handle anything a pallet jack can handle, so maybe 5000lbs. Maybe
the cheap and simple answer is a pallet jack, a good lever bar, and
a
whole stack of 2x6 lumber.

2" planks get knocked out of place too easily when you add more on
top, and can be difficult to realign without risking a hand under the
load. My cribbing collection for jacking up small buildings is mainly
4x6 and 6x6 deck post cutoffs from a contractor's junk pile and the
lower quality 6x6 cants from my sawmill. An oak 6" x 6" x 8' is the
heaviest I want to handle by myself.
