A conveyor device includes a truss; a conveyance element, which is movable with respect to the truss in a longitudinal direction and which includes at least one groove extending along said longitudinal direction. The conveyor device further includes a comb plate having at least one tooth extending into the at least one groove. For minimizing the effects resulting from a comb crash, the conveyor device further includes at least one compensation device fixing the comb plate in the longitudinal direction during normal operation, but allowing the comb plate to move in the longitudinal direction in case of a comb crash.

A drive chain (2a, 2b) for a chain drive comprises a plurality of chain links (10, 20) and joints (30) respectively connecting two of the chain links (10, 20) forming the drive chain (2a, 2b). The drive chain (2a, 2b) further comprises a plurality of carrier elements (40), each of said carrier elements (40) being linked to one of the chain links (10, 20) or joints (30) and supporting at least two support/engagement elements (43, 44), which are configured for supporting the drive chain (2a, 2b) and/or for engagement with an appropriate turnaround element (50; 90) for driving the drive chain (2a, 2b).

A plurality of steps are linked by endless step chains. Each of the steps includes: a step main body; first shafts that are disposed on the step main body; first step rollers that are disposed on the first shafts, and that are guided by the first guide rails; second shafts that are parallel to the first shafts; and second step rollers that are disposed on the second shafts, and that are guided by the second guide rails. The first shafts move along first pathways, and the second shafts move along second pathways. The second pathways are positioned inside the first pathways when viewed parallel to respective shaft axes of the first shafts. The step chains link each of the steps by joining the second shafts of each of the steps, and are disposed within a range of the step main body in an axial direction of the first shafts.
