Remote-Controlled Trailer Movers-also called dollies, tugs, pullers, pushers-are used to maneuver large/heavy, wheeled conveyances (e.g., trailers, grain wagons, machinery, campers, boat haulers) relatively short distances to/from pull-vehicles, storage areas, etc. To move an item, the Parkit360, Trailer Valet, or TRAX attaches via ball hitch (video #1); whereas the Enduro, attached to the chassis, powers alloy rollers that contact-and turn-the tires (video #2). Some models are wheeled, some tracked; all are battery-powered and operated by hand-held wireless remote. (Note. Models that deliver a pull-power of at least 10,000 pounds are recommended for moving the above items.)
