Abstract
A ramp may include a frame having first and second end portions and at least one rung extending substantially between the frame and being positioned between the first and second end portions, the at least one rung forming at least a portion of a ramp surface. The ramp may further include a plate extending substantially between the frame and being positioned adjacent to at least one of the first and second end portions, and a lip pivotally attached to the plate at a pivot axis, wherein the pivot axis is non-load bearing.

A ramp comprising:
- a frame having first and second end portions;
- at least one rung extending substantially between the frame and positioned between the first and second end portions, the at least one rung forming at least a portion of a ramp surface;
- a plate extending at least partially between the frame and positioned adjacent to at least one of the first and second end portions;
- and
- a lip pivotally attached to the plate,
- wherein the ramp is in an operative position when the plate is positioned on a loading surface and is in an inoperative position when the plate is not positioned on the loading surface, whereby when in the inoperative position with the lip engaged with the loading surface the lip pivots to release the ramp from the loading surface.
