  • Patent number: 6783315
    Abstract: The present invention 10 discloses a loading platform 14 for motor vehicles 12 that is pivotably supported by a rigid stationary frame member 32 with a central square tube 34 that connects with a conventional trailer hitch 36. The platform 14 may be locked securely to the stationary frame member 32 and released to allow for the pivoting movement thereof. A pair of bearing assemblies 42 allow for the axial rotation of the bearing blocks 46 and associated platform 14 around the bearings 44 that remain in a fixed position due to the square tube 34 extending therethrough. Pneumatic pistons 30 communicate between a central portion of the stationary frame member 32 and a distal portion of the platform 14 to provide stability and regulate the rotational movement of the platform 14.
