ABSTRACT:
Previous folding ramps for attachment to pickup truck tailgates required complicated cable supports to make them light enough to lift when closing the tailgate while strong enough to bear heavy loads when unfolded. The present invention provides a folding ramp for attachment to a pick-up truck tailgate wherein the structural support is provided by rigid parallel ribs, each rib hinged to fold flat against the underside of the ramp, and divided into separate sections which fold with the separate panels. Preferably there are two sets of parallel rib sections, each formed of sections connected by short flexible cable lengths.
