Abstract

An advanceable auxiliary conveying apparatus that comprises a trackway and an elevated roadway and conveying assembly movably attached to the trackway. The elevated roadway and conveying assembly is constructed to support a mobile conveyor thereon while receiving and conveying the material that is being discharged therefrom. An access ramp is movably attached to the elevated roadway and conveying assembly by at least one extendable cylinder that is used to advance the ramp away from the elevated roadway and conveying assembly. The elevated roadway and conveying assembly is equipped with elevation members that serve to elevate the elevated roadway and conveying assembly between a first elevated position wherein the trackway is suspended by the elevated roadway for advancement relative thereto and a second elevated position wherein the elevated roadway and conveying apparatus is movably supported on the trackway for advancement thereon. Extension and retraction of the cylinder attached to the elevated roadway and the ramp cause the trackway to be advanced forward and the elevated roadway and conveying assembly to be advanced on the trackway.
