ABSTRACT:
A lift apparatus adapted for reliable, substantially maintenance-free operation in material transfer systems, including systems that are subject to considerable contamination. The lift apparatus includes an open top container, a support plate for normally supporting the container in upright position, and a ball screw drive for moving the support plate and container between a filling station in which material may be introduced into the container and a discharge station. The container is supported for relative pivotal movement with respect to the support plate, and a chain and sprocket arrangement is provided for automatically pivoting the container to a dumping position as it is raised into the discharge station and for returning the container to its normal upright position as it is lowered from the discharge station following dumping.
