Caster arrangement for use on access floors

A caster arrangement is disclosed for cabinets used on access or raised floors of a computer room or the like. The caster arrangement allows for a small, heavy cabinet to be situated on the panels of the access floor without applying concentrated or ultimate loads on the panels that may exceed the design characteristics of the panel and access floor. The caster arrangement allows for at most three casters to apply load to a given panel while the cabinet is being moved or has an arbitrary orientation.
