ABSTRACT:
A conveyor system for loading pallets into and out of a vehicle includes an accumulating conveyor and airbag rail. The accumulating conveyor is constituted by a pair of chain rails for supporting and conveying pallets into and out of a vehicle. The airbag rail is positioned between the chain rails and adjacent to one of the chain rails. The airbag rail is constituted by a base beam, a lift beam and an airbag positioned between the two beams. The arrangement is such that, with the chain rails and the base beam fixed to the floor of a vehicle, the airbag can be inflated to raise the lift beam so as to lift an edge portion of a pallet supported by the two chain rails out of contact with one of the chain rails.
