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.
