A vehicular ramp including an inclined ramp surface cooperating with a horizontally disposed support plate includes a rear wall, with the rear wall mounting a web roll thereon, the web roll extends downwardly of the rear wall between spaced rear legs and forwardly of the ramp surface underlying a presser plate, wherein the presser plate is pivotally mounted adjacent a forward terminal end of the ramp and extends below the forward terminal end to overlie a web extending from the web roll minimizing abrasive wear to the web roll upon ascent of a vehicle of the ramp structure.
