Choosing casters rated 2,001 to 4,000 lb

Load: divide the loaded weight by three for a four-caster cart [S2]. A 3,200 lb caster from this page then suits about 9,600 lb, and the strongest at 4,000 lb about 12,000 lb.
Mount: most casters rated 2,001 to 4,000 lb use a 5-1/4 x 7-1/4 in top plate; 4-1/2 x 6-1/4 in and 4-1/2 x 6-1/2 in plates are listed too; match the bolt holes on your frame to the plate before ordering.
Floor: on casters rated 2,001 to 4,000 lb, polyurethane and rubber are kinder to tile and finished floors; cast iron, steel, phenolic, nylon and ductile iron roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid casters rated 2,001 to 4,000 lb are listed, with face contact brake, side lock brake and total lock brake options.
Heat: among casters rated 2,001 to 4,000 lb, the highest listed range is -45°F to 800°F on ductile iron; check the temperature field on each listing before oven or hot-room use.
