This is making me realize why pallet-jack front rollers are so wide, because
if they didn't at least try to spread areal load a little bit they probably
wouldn't play well with concrete warehouse floors either.  Interesting that
nobody came up with a design with two or three rollers per fork and a way
to make them all jack up in parallel.
