Abstract
The specification discloses a modular and reusable wheelchair ramp capable of ready assembly and disassembly while providing a strong and safe construction. The ramp includes a plurality of leg assemblies fabricated of PVC plumbing components and a plurality of ramp sections each extending between and mounted on a pair of adjacent leg assemblies. Each leg assembly includes a pair of legs and an interconnecting crossbar slidably received thereon for ready height adjustability. The ramp sections are hooked over the crossbars. In a preferred embodiment, handrails also fabricated of PVC plumbing components are also slidably mounted on the legs.
