ABSTRACT:
On an energy guiding chain for guiding hoses, cables or the like between two connecting points moving relative to each other, with several chain links connected to each other in articulated fashion, each of which displays two side straps and cross-pieces connecting them, where the chain consists of a strand that can be connected to one of the connecting points, and a strand that can be connected to the other connecting point, these transitioning into each other via a deflection zone, and where at least some of the chain links display runners covering the upper side of the side straps, it is envisaged that the runners be mounted on the cross-pieces at a distance from the side straps in order to reduce the assembly effort.
