Abstract
A loading and unloading device for transporting vehicles with the use of a truck which is movably and releasably secured to the bed of the truck. The device has a movable vehicle receiving floor with forward and rearward legs pivotally secured to the bed so that the receiving floor can be displaced forwardly and upwardly to lift and carry a vehicle at a height sufficient to permit the placement of another vehicle on the truck bed and beneath the floor. A power cylinder, preferably one or more hydraulic cylinders, is used to selectively raise the receiving floor and carried vehicle upwardly and forwardly of the bed so that the weight of the car is more evenly distributed over the truck. The elevated vehicle is positioned more near the front wheels and axle of the truck to enable better truck handling and control. The configuration of the receiving floor, the truck bed and the pivotally secured legs always forms a parallelogram so that the vehicle being raised is substantially level at all times. The device does not interfere with the towing of a third automobile thus enabling the transportation by a single vehicle of three other vehicles such as automobiles.
