Abstract: A bulk conveyor system has a longitudinally extending conveyor belt, devices at the ends for tensioning and relaxing the belt and for advancing the belt, a carriage movable along the belt between the ends, and a transverse conveyor cooperating with the belt, mounted on the carriage, and extending from the belt to a pickup/deposition location. This conveyor is laterally shifted through a predetermined turnover distance by first displacing the carriage longitudinally along the belt from one of the ends to the other end while lifting the belt and deflecting it transversely at the carriage along an S-path through the turnover distance thereby leaving the belt offset transversely at the other end by the turnover distance from the one end. Then the belt is arrested and transversely shifted at the other end of the belt by the carriage through twice the turnover distance. The belt is then relaxed and the device at the other end is shifted transversely by the carriage through twice the turnover distance.

A vehicle for shifting the conveyor system in a lateral direction includes an arm for engaging the conveyor and for applying lateral shifting forces to the conveyor. The conveyor system includes a series of skids spaced along the longitudinal axis of the conveyor and aligned parallel with the lateral axis of the conveyor. A pair of side rails are positioned on opposing ends of the series of spaced apart skids. The side rails are pivotally connected to the skids to maintain a predetermined spacing therebetween. The side rails also receive the lateral forces from the arm of the vehicle and translate the shifting forces exerted by the arm into lateral movement of the skids. A plurality of rigid conveyor modules are positioned between the side rails and above the skids to support the conveyor belt.

Abstract: A crossover dump and conveyor advancer for a main conveyor means supported by a movable pan line. The crossover dump includes a tunnel portion through which the pan line extends and entry and reentry ramps supporting portions of the main conveyor are provided for carrying the main conveyor over a secondary conveyor which extends cross-wise to and above the pan line. Material carried by the main conveyor is moved up the entry ramp where it then falls onto the secondary conveyor. A conveyor advancer is included to move the pan line relative to the crossover dump in order that the conveyor system may be advanced or retracted. The main conveyor is adapted to connect with a continuous mining machine by way of a bridge conveyor. The pan line supporting the main conveyor has limit switches near the tailpiece which when contacted by the bridge conveyor will cause the conveyor advancer to advance or retract the pan line.
