Abstract
An improved portable ramp structure constructed of light-weight material and adapted for reliable and safe use with various transport vehicles is described. A plurality of pairs of longitudinal support members having longitudinal channels for mounting a predetermined number of cross members therebetween are shown, with ones of each of said pairs hingedly mounted to associated ones of other pairs, such the ramp may be longitudinally folded. Each of said pairs of members has a support member mounted at one end thereof for cooperating with some portion of a transport vehicle. Retention chains with associated hooks are described for removably attaching the ramp structure to the transport vehicle. The entire structure is comprised of components that are fabricated from extruded lightweight material, and cut to length for assembly.
