ABSTRACT OF THE DISCLOSURE A scraper chain conveyor assembly comprises a plurality of trough sections arranged in end-to-end relationship and a bracket side section extending along each trough section. Each bracket side section includes a hollowed sectional part and a mining machine embraces the sectional part and has a sprocket wheel which engages through an elongated slot defined in the sectional part, A round link chain extends through the hollowed sectional part and has respective crossing links held by the sectional part in link-crossing orientation so that one of the crossing links is oriented for engage- ment by the sprocket wheel engaging through the slot. A round link chain is subdivided without any separation of the chain links from each other into chain strand sections which are equal in length to the length of the individual trough sections and these chain strand sections are associated with the trough sections in a manner such that they leave a predetermined clearance of motion for the chain strand in the longitudinal direction thereof. Preferably, oblong slots are defined so as to extend transversely through the hollowed sections and crossbolts are arranged in the oblong slots so that they have a clearance of motion which equals the clearance of motion predetermined for the chain strand sections. Each strand section is preferably equipped with at least two crossbolts spaced along its length.
