  • Patent number: 4750856
    Abstract: A car carrier having a bed linked to the frame of a truck for movement from a horizontal position on the frame to a tilted car loading or unloading position in a single motion entailing simultaneous upward-rearward movement of the front end of the bed and downward-rearward movement of the rear end of the bed to ground-engaging position. The terminal portion of the tilting movement of the bed automatically compresses the rear springs between the frame and rear axle. The car carrier also has a wheel lift assembly including yokes on a rearwardly extending boom which are lowered to engage and lift the front on rear wheels of a second car responsive to partial tilting of the bed and to return of the bed to horizontal position. The boom and yokes are retracted forwardly to be disposed underneath the rear portion of the bed during loading and unloading of a first car onto or from the bed.
