Abstract
Chain links and a conveyor chain that is highly resilient, in a tensile direction, for a moving walkway, an escalator or a lift. A chain link can include two chain link connector receiving regions arranged at opposing ends for receiving a chain link connector, which mechanically connects two neighboring chain links to one another in such a way that a tensile force can be transmitted therebetween. The chain link can also include a loop closed in a ring shape and surrounding the two chain link connector receiving regions. The loop can be formed with a fiber composite material. The fiber composite material is preferably in the form of a loop-like closed band, in which fibers, such as carbon fibers that can be subjected to high levels of tension, are embedded in an elastomer-matrix material.
