ABSTRACT OF THE DISCLOSURE A road vehicle for loading and unloading containers has a tiltable frame on which a carriage runs, the carriage having a pair of clamps to engage the lower front corners of a container located at the rear of the vehicle. To load a container, the vehicle is driven backwards to the container and the frame tilted until its rear end rests on the ground in front of the container. The carriage is run down the inclined frame by a winch-and-cable assembly and the clamps are secured to the container. As the carriage is pulled back on the frame, it lifts the front end of the container; the vehicle, with its transmission in neutral, moves rearwardly under the container being lifted without, however, being contacted by the frame. At one stage of the loading operation, a pair of longitudinal side elements on the frame are raised out of their gutters to contact under parts of the container to permit the container to be slid on the frame while maintaining a distance between the container and the frame. At the end of the pulling action, the frame is lowered to rest the container on two front support elements mounted to the chassis of the vehicle while the other two are mounted at the rear of the frame. Then, the longitudinal side elements are lowered in their respective gutters to permit the container to rest also on two rear support elements mounted at the rear of the tiltable frame. Thus, at all times, a distance is maintained, during loading, unloading or transport, between the frame and the bottom of the container.
