ABSTRACT:
An arrangement for guiding on a coal bank side a coal cutting machine at a conveyor trough with guide section portions for a round-link chain which is engaged by a chain drum which drives the cutting machine. The abutting ends of the guide section portions are constructed without upper guides and have overlapping joint projections. In addition the abutting ends of the guide section portions are connected to each other through chain guide members which extend across the joint area. The chain guide members are connected through connecting bolts while maintaining a predetermined play to the trough portions, wherein the chain guide members have corresponding recesses in the area of the guide section portion which is free of upper guides. As a result, the round-link chain is guided so as to be aligned in the abutting areas and the round-link chain is easily accessible.
