ABSTRACT:
A roll up ramp system facilitates transition between a first elevation and a second higher elevation. The roll up ramp system includes a plurality of load-bearing links connected to one another having top and bottom faces and being comprised of at least one load-bearing member and a set of side plates. Each side plate has at least two apertures appointed for receiving and housing a pin, or the like, for pivotally connecting the load bearing links to one another. The load-bearing links are adapted to rotate about the pin to form an extended ramp configuration and a roll up configuration when force is applied to the roll up ramp structure. The roll up ramp is adapted to achieve a rigid, durable ramp configuration, which is readily utilized for loading equipment into a hauling device. Advantageously, the roll up configuration achieved by the ramp structure provides for convenient storage thereof.
