A hydraulically elevatable ramp apparatus is set forth wherein a ramp formed of an upper and lower portion with a pivotal hinge joining the two portions secured to a hydraulic jack at a forwardmost position. The ramp at a first lowered position accepts vehicles of diminished ground clearance wherein the vehicle is thereafter elevated to a second position whereupon the lower hinged portion is automatically repositioned upon elevation of the upper portion. The jack is formed with a resilient pad to insure a non-slip arrangement upon elevating a vehicle to a second elevated position.
