Choosing hollow kingpin casters

Load: plan on three casters carrying a four-caster cart [S2]; at 300 lb each, a common rating here, that is about 900 lb, and the 350 lb top rating covers about 1,050 lb.
Floor: on hollow kingpin casters, rubber and polyurethane are kinder to tile and finished floors; polyolefin rolls easier under heavy loads on smooth concrete.
Rig: swivel and rigid hollow kingpin casters are listed, with total lock brake and top lock brake options.
