摘要

A conveyor belt system drive has at least one drive at the head drum or head drums. At least one non-driven relieving roller is arranged in a vicinity of each of the driven upper belt middle rollers. A device brings the driven upper belt middle rollers into a position spaced a distance from the belt. The driven upper belt middle rollers can be removed from the belt for maintenance operations or replacement. It is not necessary to stop the conveyor belt system in case of a defect of a driven upper belt middle roller to repair or replace same. The non-driven relieving roller advantageously assumes the support function of the driven upper belt middle roller, when this is located in the position spaced at a distance from the belt. The driving power of the conveyor belt system is dimensioned such that failure a driven upper belt middle roller can be compensated.
