Abstract: A portable folding ramp used for ascending or descending an object or platform. The ramp is comprised of a plurality of rectangular panels, respective ones of adjoining panels being pivotably hinged along adjacent sidewalls such that the ramp may be folded into a compact first state, or unfolded into a second state where the ramp may support a load. The ramp includes a cable and hinge system positioned on the underside of the panels to provide structural support to the ramp in the second state while allowing the panels to be folded into the compact first state.
