Claim 1
Independent Claim
282 words
A vehicle carrier comprising a frame, front and rear wheels supporting the frame, a flat bed supported on the frame and projecting rearwardly of the rear wheels, a ramp pivotally connected at its forward edge to the rear edge of said flat bed and movable between a loading position in which the distal end thereof is on the supporting surface for said wheels and a vehicle-carrying position in which the distal end thereof is above the plane of said flat bed, a winch mounted on said frame at the forward end of said flat bed for use with a cable to pull a vehicle onto said ramp and flat bed when the ramp is in its loading position, a pair of hydraulic cylinders pivotally connected at their opposite ends to said frame and to the underside of said ramp for moving said ramp from its loading position to its vehicle-supporting position, each of said hydraulic cylinders being pivotally connected at one end to said frame at a location spaced below said flat bed and at the other end to said ramp at a location spaced below the undersurface of the ramp and adjacent to said forward edge, the pivotal connection of the hydraulic cylinders at said one end being spaced a greater distance below said flat bed than the pivotal connection of the other end of the hydraulic cylinders is spaced below the undersurface of said ramp, and struts mounted on the undersurface of the ramp and extending in axial alignment with said hydraulic cylinders from the locations of pivotal connections of the cylinders with the ramp to rearward locations of rigid connection of the struts with the undersurface of the ramp.
