The 20,001-30,000 lb tier sits between the 15-20 ton extreme range and the 30,000+ lb catalog ceiling. A four-caster platform carries 80,000-120,000 lb — large machine tools, powergen sub-assemblies, heavy fabrication and defense platforms. Hamilton's Ultra Maxi-Duty UMD2 and comparable dual-wheel builds serve this band.
Dual-wheel kingpinless construction is effectively standard here — two wheels per caster split the 20,000-30,000 lb load across two contact patches, keeping wheel diameter and deck height manageable while the rating stays extreme. Dual-row tapered roller bearings carry the radial weight and cornering thrust together. Forged steel or heavy polyurethane-on-forged-core wheels; the choice is set by the floor.
Standard concrete fails at this load. The minimum is 6-8 inch reinforced concrete; embedded steel rail is the spec for permanent travel paths. Movement is powered without exception — a tow vehicle sized to an 80,000-120,000 lb platform. Plan the floor and the tugger into the project from the start, not after the casters arrive.
