ABSTRACT:
The lifting and tilting device includes fluid actuated bellows type of lifting motors which lift and tilt a container with respect to a base. The lifting motors are supported by pairs of scissor mechanisms which pivot with respect to one another when the lifting motors expand and contract. The scissor mechanisms are partially slidable with respect to the base and the container to permit raising and lowering of the container. The container is designed to receive material at a certain level and then dispense of the material at the same or different level. The fluid preferably used is air.
