ABSTRACT:
A vehicle loading ramp (10) broadly comprises a first load-bearing platform (16), a second load-bearing platform (20) preferably substantially identical to the first platform (16), and a brace (20) that can be positioned between the platforms (16,18) in order to adjust and rigidly fix a distance between the platforms. In each of several embodiments, the brace (20) may be configured to adjust the distance between the platforms (16,18) in order to accommodate different offsets between wheels of different wheeled vehicles. The brace (20) can also fix the distance between the platforms (16,18), thereby providing rigidity and preventing the platforms (16,18) from moving with respect to one another, either laterally or longitudinally.
