I have a 75# shop cart with four 150# rated casters from my local
lumberyard. I loaded a 90# panel (gently) onto the cart and pushed it
across the shop - crossing two joints in the concrete floor. Two of
the caster wheels failed.

Right now I'm thinking about plastic-tired steel wheels with a minimum
rating of 600#.
