Abstract
There is provided a self-propelled conveyor for use in mining operations having an endless revolving conveyor strand driven in its longitudinal direction by intermediate drives and guided on a conveyor frame which consists of segments multi-directionally pivotally connected to one another along the central longitudinal axis of the conveyor. The conveyor frame has downwardly extendible support elements which, for the conveying operation, lift the conveyor strand reversing in the lower stringer from the ground when the support elements are extended. For the transporting operation, the support elements are retracted so as to permit the strand to lie on the ground. Between the segments of the conveyor frame disposed in the front region of the conveyor there are steering cylinders by means of which the angle between these segments can be adjusted so as to direct the longitudinal direction of the conveyor.
