A compact, hinged, foldably deployable ramp is provided in a base configuration which includes three evenly radiused sections which connect to a deck member and have a tube, known as a coping, separating the ramp from the deck. In the base configuration, a top section, mid section and lower section each have a pair of ladder structures which share a middle flange. The deck member includes a pair of angled leg members which are designed to provide support throughout the range of engagement of the ramp. Even size and radiusing of the sections enables continued extension of the ramp by adding sections in conjunction with longer support legs for the deck.
