Abstract
A method and apparatus for moving objects, such as pallets, between an upper horizontal conveyor and a lower horizontal conveyor. A lift raises the pallet from a lower conveyor, and a clamp disposed above the lift with inwardly and outwardly pivotable arms, having inwardly facing fingers at the ends of the arms, clamps the pallet and raises it up to be substantially coincident with the upper conveyor's pallet-supporting surface. A pusher displaces the pallet from the fingers to the upper conveyor. The apparatus can also be operated in reverse to lower pallets from an upper conveyor to a lower conveyor if a fastener, such as electromagnets, is mounted to the end of the pusher.
