A load transport device that mounts to a vehicle mounted trailer hitch. The load transport system comprises a channel portion fitted with a pinion gear, and the channel portion is rigidly attached to a mounting bar that slideably engages a receiver portion of a vehicle's trailer hitch. The device also comprises an invertible shaft with an optionally-motorized rack gear system. The invertible shaft has a channel portion insertion end and a load lifting end. The invertible shaft slideably engages in either a load-low or load-high orientation depending on which end, the insertion end or the load lifting end first engages with the channel portion. The pinion gear and the rack gear system are functionally engaged. The load transport device further comprises a load support member attached to the load lifting end and comprising one or more bars that support a load.
