Abstract
A load carrier frame is disclosed which includes a spaced pair of fabricated rails. Each rail includes a longitudinal carrier axle track to receive therein the respective ends of a luggage carrier or other wheeled vehicle axle. The track is shaped to elevate the vehicle wheels above the bottom of the fabricated rails to permit sliding the carried load up and down flights of stairs and to lower the vehicle wheels below the bottom of the fabricated rails to permit the vehicle wheels to be utilized to roll the load over longitudinal surfaces with the load carrier frame attached to the wheeled vehicle.
