Abstract: Apparatus for mounting, demounting and tipping a container designed to be carried on a motor vehicle in which a four bar linkage is mounted both to the vehicle and to the container. For mounting and demounting, the four bar linkage is made linearly translatable along the bed of the vehicle. Hydraulic piston and cylinder arrangements are provided to pivot select links of the four bar linkage to a position in which the container is placed on the ground. For tipping, select links of the four bar linkage are rendered immobile with respect to each other and a piston and cylinder assembly activated to tip the container on the vehicle bed.
