Abstract
A rotary dump wagon for handling ballast having a carriage with a first conveyor mounted thereon for conveying ballast the length of the carriage and a plurality of hollow drums supported by the carriage and engaging the first conveyor for rotational movement thereabout. Each drum has a plurality of elongated flights mounted to the inner surface thereof for lifting ballast to the first conveyor and at least one downwardly extendible plow blade suspended therein which selectively contacts the upper surface of the first conveyor thereby diverting ballast traveling thereon to the lower portion of the drum. A second conveyor is pivotally mounted to the carriage subjacent the discharge end of the first conveyor for horizontal movement about a vertical axis and extends upwardly and forwardly beyond the forward end of the carriage and above the first conveyor.
