LOADING RAMP
A loading ramp is supported between a first surface and a second surface. The loading ramp includes a first ramp portion supported on the first surface. The first ramp portion includes a first rail portion extending between a first end and an opposing second end. The first rail portion extends along a first non-linear axis. A first tread portion is fixedly attached to the first rail portion and supports a weight when the first tread portion is attached to the first rail portion. The loading ramp includes a second ramp portion attached to the first ramp portion and supported on the second surface. The second ramp portion includes a second rail portion extending between a third end, which is attached to the first rail portion, and an opposing fourth end. A second tread portion is fixedly attached to the second rail portion and supports the weight.
