Choosing keyway drive wheels

Load: divide the loaded weight by three for a four-wheel cart [S2]. A 1,500 lb wheel from this page then suits about 4,500 lb, and the strongest at 2,250 lb about 6,750 lb.
Floor: on keyway drive wheels, polyurethane protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
