Abstract: A stacker includes a base having a dolly-receiving area into which a dolly can be rolled. A vertical structure extends upward from the base. A pair of arms are pivotable toward and away from one another and toward and away from an area above the dolly-receiving area. The pair of arms are movable vertically relative to the vertical structure and are configured to engage containers supported on a dolly in the dolly-receiving area. In an alternate stacker, the pair of arms may be configured to revolve about an axis generally parallel to the arms and spaced away from the arms. In this manner the arms can dump the contents from a bin engaged by the arms.
