<p>The mobile ramp secures a motor vehicle in position on lifting platform. It comprises a pair of cradles (20) accommodating the front or rear wheels (21), and coupled together by a cross-beam. The cradles are supported by a first set of rollers (23) running on the top flanges of the lengthwise platform girders (5), and by a second set of rollers (24) running against the outside of the webs of these girders. To support the wheels not in the cradles, there can be a pair of plates detachably mounted on the later, and having vertical flanges fitting in slots on the cradles, inside which are supports by which they rest on the girders.</p> |
