A cargo carrier having a U-shaped hitch sleeve on its bottom and legs with wheels on its sides. A hitch shaft is inserted into a trailer hitch on a vehicle and the U-shaped hitch sleeve fits over the hitch shaft. The legs have an internal screw type jack mechanism to raise and lower the cargo carrier to place the U-shaped hitch sleeve above and over the hitch shaft, and to raise the legs so that the vehicle can transport the cargo carrier on the hitch shaft without having to remove the legs. The wheels allow the cargo carrier to be portable when not connected to the vehicle. They also allow the U-shaped hitch sleeve to be aligned above the hitch shaft to permit lowering the U-shaped hitch sleeve down over the hitch shaft for the insertion of bolts through the U-shaped hitch sleeve and hitch shaft, thereby fastening the cargo carrier to the hitch shaft. The legs are positioned inside the cargo carrier, and a continuous loop chain engages all the legs so that adjustment of one leg adjusts all of the legs simultaneously to raise or lower the cargo carrier. |
