Abstract: A method and apparatus for unloading bulk mail vans in accordance with which the conventional roll-in or piggyback unloading dock conveyors of bulk mail handling centers, such as are operated by the United States Postal Service, are equipped with an auxiliary load receiving conveyor that serves as an implement which provides for largely mechanical transfer of the individual bags and cartons of the bulk mail from their positions of rest in the vehicle to the roll-in conveyor. The auxiliary conveyor is located at the load receiving end of the roll-in conveyor and comprises a positionable conveyor head in the form of a cantilever mounted belt conveyor apparatus having an upright two wheeled chassis that has a draft type connection to the roll-in conveyor frame for movement part and parcel with the roll-in conveyor to bring the conveyor in through the vehicle end opening into close adjacency with the stacked bags and cartons that form the bulk mail to be handled.
