Abstract
An elevating ramp for vehicles comprising a first ramp section disposed at a preselected angle with respect to the horizontal whereby the vehicle may ascend the said ramp section until the entire vehicle is disposed thereon, and a second ramp section connected with the first ramp section for receiving the vehicle thereon, said second ramp section being disposed at a greater angle with respect to the horizontal than the first ramp section whereby the vehicle may be moved through a total angular dimension with respect to the horizontal which is greater than the physical characteristics of the vehicle normally permit. When the vehicle has been positioned on the apparatus, the position of the ramp may be hydraulic adjusted for supporting the entire vehicle in a substantially horizontal position elevated above the surface of the ground.
