Abstract
An excavating loading system is disclosed which includes a vehicle with an excavating wheel assembly at the front and a plurality of conveyors toward the rear. The conveyors of the excavating and loading system include cross conveyors and a main conveyor for receiving material from the excavating wheels. The main conveyor transports the material rearwardly from the excavating wheel assembly and delivers the material to the opposite end of the vehicle. An auxiliary conveyor assembly is pivotally supported at the rear end of the vehicle to receive material from the main conveyor and to transport the material either laterally or rearwardly. The auxiliary conveyor assembly has inner and outer conveyors mounted with the discharge end of one conveyor adjacent the receiving end of the other conveyor. The conveyors are connected so that the outer conveyor can be folded under the inner conveyor. Also, the conveyors in the auxiliary conveyor assembly can be selectively positioned to discharge material from the end of either conveyor. A variably positionable deflector plate is provided to direct the discharge of material.
