The invention relates to chain links (52) and a conveyor chain (50), which can be assembled with same and which is highly resilient in a tensile direction, for a moving walkway, an escalator (1) or a lift (90). A chain link has two chain link connector receiving regions (54) arranged at opposing ends of the chain link (52) for receiving a chain link connector (62), which mechanically connects two neighboring chain links (52) to one another in such a way that a tensile force can be transmitted from one chain link to the neighboring chain link. The chain link (52) also has a loop (56) closed in a ring shape and surrounding the two chain link connector receiving regions (54). The loop (56) is formed with a fiber composite material (57). The fiber composite material (57) is preferably in the form of a loop-like closed band, in which fibers (58), such as carbon fibers that can be subjected to high levels of tension, are embedded in an elastomer-matrix material (60). The chain links (52) are therefore very resistant to tension, however they are flexible in a bending direction (63) perpendicular to same. With a deflecting of the conveyor chain on a conveyor wheel, using support structures that are radially outwardly supporting the loop (56), the shape of the chain links is adapted to that of the conveyor wheel, and in this way, polygon effects and resulting jerking during the conveying of the conveyor chain are avoided.
