Abstract An improved elevating assembly for the upper platform of a road transport vehicle carrier, of the type having an upper platform supported on a plurality of front and rear posts which in turn are supported on the lower platform. The lower ends of the front and rear posts are mounted for movement lengthwise along the lower platform thereby to raise and lower both the front end and the rear end of the upper platform. A strut is pivotally connected at its upper end to a point intermediate the length of each post. In the present invention, the strut is a bell crank lever pivotally interconnected at its elbow to the lower platform and at its lower end pivotally interconnected with one end of a ram that is pivotally connected at its other end to the platform. The ram contracts to raise the upper end of the strut and has lost-motion connection with the strut.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
In a road transport vehicle carrier having a lower platform and an upper platform and support posts extending from the lower platform to support the upper platform at such a height that vehicles can be accommodated on both platforms when vehicles are being transported on the carrier, the upper ends of the posts being pivotally connected to the upper platform and the lower ends of the posts being movable lengthwise along the lower platform thereby to raise and lower the upper platform, and a strut pivotally connected at its upper end to each post and pivotally connected to the lower platform at a distance from its upper end; the improvement in which the strut is pivotally interconnected with the lower platform intermediate its ends and has an extension arm beyond its pivotal connection to the lower platform, and a ram acting between said extension arm and the lower platform to raise and lower the upper platform.
Claim 2
Dependent Claim
