ABSTRACT:
A portable ramp assembly has many uses, but is especially designed to fit within the flat bed of a pick-up truck which, for example, has an eight foot long flat bed. The assembly comprises a housing which is sufficiently wide to accommodate two separate ramps in side-by-side separated relation. The housing is provided with special blocks for engaging the trailing ends of the ramps and lifting them to be closely aligned with the top, exposed surface of the housing, so as to at least reduce any abrupt offsets between the tops of the housing and adjacent trailing ends of the ramps. Special plastic guides are provided between the ramps and housing to facilitate movement of the ramps and keep them in proper lateral alignment as they move into and out of the housing.
