ABSTRACT:
A ramp assembly includes at least one ramp having a plurality of oppositely situated side rails and a mechanism for selectively locking the ramp at an extended position. The ramp assembly further includes a mechanism for selectively articulating the ramp between a folded position and an extended position. A plurality of linear support runs having opposed end portions are secured to the side rails such that the support runs become medially positioned therebetween and define a surface area along which a vehicle can be supported. Selected ones of the support runs include mounting brackets attached thereto. A flange member is secured to one of the support runs and extends outwardly therefrom. The articulating mechanism includes a hinge member having a pair of pivotally connected plates repeatedly adaptable between the folded and extended positions respectively.
