Abstract
An assembly “(42)” including a fluid levitated caster and a debris scraper “(31)” device positioned external to a levitation membrane “(11)”. Assembly “(42)” levitates heavy loads upon a near frictionless pressurized fluid, and also sweeps aside potentially membrane destructive debris “(25)” from a floor “(27)” in the path of movement. The external debris scraper “(31)” function does not noticeably increase movement friction, and does not require increased power air flow or consumption.
