ABSTRACT:
An improved method and apparatus is disclosed for turning an articulated self-propelled conveyor which is adapted either for conveying materials or for movement along the surface of the earth, including a plurality of segments pivotally joined to form an elongated housing. The housing has an upper and lower surface with jacks attached to the segments for selectively lifting or lowering the elongated housing. A conveying apparatus is mounting along the upper and lower surfaces and connected between the upper and lower surfaces. Transverse flights are mounted to the conveying apparatus such that when the jacks have elevated the elongated housing the conveying apparatus will move material along the upper surface of the elongated housing and when the jacks have lowered the elongated housing against the surface of the earth, the conveyor apparatus will move the elongated housing along the surface of the earth. The turning capability of the self-propelled conveyor is enhanced by tapering the surfaces of the transverse flights which are in contact with the earth in a manner so that when the housing turns the portion of the conveyor in the turn will tilt into the turn so that the vertical axis of the segments in the turn will be slanted toward the inside radius of the turn.
