  • Patent number: 4109809
    Abstract: A trailer adapted to carry a plurality of vehicles includes a plurality of wheels rotatably mounted on a frame to support it rollably above the ground, and a pair of vehicle-supporting trailer beds normally disposed in a use position in side-by-side relationship in a common horizontal plane on the frame for each supporting individually from below one of the vehicles to be carried. Each one of the vehicle beds is hingedly mounted to the frame at a position forwardly of the mid-point of the beds to enable them to tilt individually and independently backwardly until the rear edges thereof contact the ground so that the vehicles to be carried can be driven up onto the beds to enable the thus loaded beds to tilt back to their use position under the weight of the vehicles. Latches are provided for holding the beds releasably in their use position.
