Device for removing a container 1 from all lorries 2 of 1000 kgs or more. Once this container is brought out onto the ground, a device for doubling or tripling the width thereof. Four or more jockey wheels 3 pivoting in the region of the floor, bring the floor level of the container to that of the lorry, whereas they only exceeded by 10 mm in the vehicle 2 allowing sliding. The device is made up with the aid of two threaded rods 4 placed on each side of the vehicle 2 and actuated by a crank 5 allowing the displacement on these two threaded rods of two tapped blocks 6 which, pushing the container back, cause it to be removed, or by bringing it forward load it into the vehicle 2. These two blocks possess, at 7, a hole enabling the passage of two pins for connecting the two plates of the container 1. Upon unloading of the container 1 in order to double its width with a box 8 coming out with the aid of nuts fixed at 9 screwing onto four threaded rods 10 rotating in the same direction with the aid of a crank 11 and a set of gears. For the case of two boxes 8, coming out on either side of the container 1 tripling its width, eight threaded rods 10 are provided, five of which rotate in the opposite direction. This device allows the bulk of a volume to be reduced in transport and practically re-establishes the volume in use on the ground. IMAGE
