Patent ID: 8251199

Claim:
A conveyor apparatus comprising: a frame, the frame having a base and a plurality of rotatable members attached to the base, the rotatable members rotatable to move the frame directly on ground; a cross conveyor, the cross conveyor having a moveable belt sized and configured to receive and move material, the cross conveyor supported by the frame; and the frame positionable adjacent to a mobile bridge conveyor having a tripper conveyor device such that a portion of the cross conveyor is positionable under an upper end portion of the tripper conveyor device to receive material from the tripper conveyor device, the mobile bridge conveyor having a frame that moveably supports a conveyor of the mobile bridge conveyor and the tripper conveyor device of the mobile bridge conveyor, the frame of the conveyor apparatus being moveable relative to the mobile bridge conveyor when adjacent to the mobile bridge conveyor and the frame of the conveyor apparatus being moveable independent of the mobile bridge conveyor and the tripper conveyor device such that the cross conveyor is moveable independent of the mobile bridge conveyor and the tripper conveyor device when located under the upper end portion of the tripper conveyor device; a controller communicatively coupled to at least one of the frame of the conveyor apparatus and the mobile bridge conveyor; at least one sensor, each sensor of the at least one sensor attached to at least one of the frame of the conveyor apparatus and the cross conveyor; the controller actuating movement of one of the mobile bridge conveyor and the frame of the conveyor apparatus to adjust a position of the one of the mobile bridge conveyor and the frame of the conveyor apparatus when the controller determines that the conveyor apparatus is positioned more than a first predetermined distance away from the mobile bridge conveyor so that the one of the conveyor apparatus and mobile bridge conveyor is moved such that the conveyor apparatus is positioned within the first predetermined distance of the mobile bridge conveyor; the controller receiving data from the at least one sensor to determine that the conveyor apparatus is positioned more than the first predetermined distance away from the mobile bridge conveyor; and the controller actuating movement of one of the mobile bridge conveyor and the frame of the conveyor apparatus to adjust a position of the one of the mobile bridge conveyor and the frame of the conveyor apparatus when the controller determines that the conveyor apparatus is positioned less than a second predetermined distance away from the mobile bridge conveyor so that the one of the conveyor apparatus and mobile bridge conveyor is moved such that the conveyor apparatus is positioned more than the second predetermined distance away from the mobile bridge conveyor; the controller receiving data from the at least one sensor to determine that the conveyor apparatus is positioned less than the second predetermined distance away from the mobile bridge conveyor.
