A fluid levitating caster lifts a heavy load "( 17 )" off a floor "( 18 )" with near friction-less-ness for transport has integrated a load lifting device. This extra rise height "(ER)" lifting feature accommodates moving loads "( 17 )" which have flexible-sagging frames, over uneven floors "( 18 )", and which have frames that are not parallel to floor "( 18 )". An inflatable bellows "( 22 )" design of the load lifting device receives its pressurization from fluid levitating caster, and additionally serves as a dampening reservoir to reduce hopping-pressure surges inherent in fluid levitating casters.
