摘要：
A pet ramp system has a central pier and at least one ramp with an axle that is received in an axle receiver disposed near the top of the pier. The axle is disposed inwardly, in both a fore and aft direction and in a transverse direction, from a base perimeter of the pier. The piers axle receiver(s) permit installation of the ramp axle when the ramp is in a vertical orientation, but the receiver(s) will not permit separation of the ramp from the pier when in use.
