Abstract:
1. A ramp assembly comprising: a ramp including a sheet and a framework formed on an underside of the sheet supporting the sheet, the ramp having opposed downstream and upstream ends; a landing including a downstream end and an upstream end, wherein the downstream end of the landing is coupled to the upstream end of the ramp and is aligned parallel with respect to the upstream end of the ramp, and the upstream end of the landing is aligned transverse with respect to the downstream end of the landing; a bridge mounted to the upstream end of the landing and extending transversely away from the upstream end of the landing; a hinge assembly coupling the landing to the ramp, the hinge assembly having a first leaf mounted to the ramp and an opposed second leaf free of the ramp; a bracket configured to receive the second leaf of the hinge assembly, the bracket carried on the landing; a post on the bracket disposed in contact with the first leaf to support the ramp, wherein the post defines a slot in the bracket which receives the second leaf and prevents movement of the second leaf in the bracket; and the framework is inboard from the upstream end of the ramp, defining a receiving area formed between the underside of the sheet and the framework, the receiving area configured to receive the bracket on the landing.
