Load: plan on three wheels carrying a four-wheel cart [S2]; at 500 lb each, a common rating here, that is about 1,500 lb, and the 1,200 lb top rating covers about 3,600 lb.
Floor: on thermoplastic rubber wheels, rubber protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
