Abstract:
An energy guiding chain for guiding cables or hoses, comprising:a plurality of chain links connected to one another in articulated fashion, the chain links including parallel straps, and cross-members connecting the straps of a given chain link, the articulation permitting the chain to move in such a way so as to form an upper strand, a lower strand, and a deflection zone connecting said upper and lower strands, the straps having narrow sides that form top and bottom surfaces of the straps when the respective link is in the upper or lower strand, and wherein at least one said chain link includes two said cross-members at a distance from one another in the longitudinal direction of the chain on at least one narrow side of the chain straps; wherein at least some of the chain links of at least one of the upper strand and the lower strand include rollers, and wherein at least some of the chain links of the other of the upper strand and the lower strand include running surfaces, the rollers being arranged such that when the energy guiding chain travels the rollers on one strand can roll on the running surfaces on the other strand.
