Abstract: The invention is directed to a suspension for the running rail of a lifting mechanism at a girder, with a cable connecting the girder and the running rail. The ends of the cable are detachably connected with one another by a connection element. To prevent tearing of the redundant suspension or to prevent the cable clamps from damaging the cables in the event of sudden loading, for example, if the primary running rail fastening system tears or breaks, the connection element formed of two wedge locks connected to one another are arranged in such a way that one wedge lock is rotated by 180 degrees relative to the other wedge lock. Accordingly, the working directions of the wedges clamping the ends of the cable are oppositely directed. The ends of the cable which run in from opposite directions can be guided back in the direction opposite to their running-in direction after deflection around the wedges of the wedge locks such that they can be clamped by the wedges, at least under load.
