A chain conveyor comprises a roller chain (6) [should read "8"] and a supporting rail (5) for vertically supporting the roller chain (6) [should read "8"]. The roller chain (6) [should read "8"] consists of a plurality of supporting rollers (3) that are interconnected by means of chain links (1). The chain links are of U-shaped design inasmuch as they comprise two legs (11, 12) and a base portion (10) located there between. The mean length (L) of the base portion (10) corresponds at least approximately to the distance (A) of the axes of two adjacent supporting rollers (3). The front faces of adjacent base portions of adjacent chain links are correspondingly designed and act as stops, inasmuch as they limit the mutual rotating movement of adjacent chain links, exceeding a predetermined angle, in such a way that the roller chain can transmit thrust forces. For laterally guiding the roller chain, discrete guiding elements (2) are provided which are inserted into the shafts that interconnect the chain links in an articulated manner.
