Abstract
A conveyor chain for a transporting plant in which each chain link made of a synthetic material includes a plate for supporting the material to be conveyed, a head piece provided with a cylindrical bore and a yoke-shaped portion with two legs extending from the head piece. For cardanically coupling two chain links, a bolt rotatably inserted in the cylindrical bore of the head piece is provided with a transverse bore and the legs of the chain link are provided with bores in alignment with the transverse bore, wherein a metal connecting pin is inserted into the transverse bore of one chain link and in the bores of the legs of the preceding chain link in travel direction. The bolt inserted into the bore of the head piece has a recess and a roller is placed in the recess, wherein the roller is rotatably supported on the connecting pin, the roller is in engagement with the teeth of a drive wheel and the roller is of a synthetic material having a higher strength than the synthetic material of the head piece. In addition or alternatively, a reinforcement insert is placed on the sides of the legs of the yoke-shaped portion which face each other.
