ABSTRACT:
A cargo-work vehicle for detachably supporting a container has lift arms for rotatably supporting the container and a single cooperating auxiliary arm which ensures that the attitude of the container is held constant when the container is loaded and unloaded. A dump pin is also provided for fixing the container relative to the lift arms so that the container can be rotated relative to the vehicle body for dumping of the container load. The single auxiliary arm is advantageous because it can be located centrally of the vehicle and substantially underneath the loaded container. Such placement of the auxiliary arm affords compactness, reduces costs, and allows a single auxiliary arm to maintain the desired, constant attitude of the container during loading and unloading of the container.
