The invention relates to an energy conduction chain for conducting hoses, cables or similar, wherein the upper strand lies on top of the lower strand and rollers (5, 6) are provided on at least some chain links of the upper strand and/or of the lower strand. Said rollers can be rolled on running surfaces (9, 10) provided on the chain links of the opposite strand and have, on their running surface, a plurality of continuous guide grooves which are arranged at a distance from each other. Teeth (13, 14) of the rollers of the opposite strand can engage in said guide grooves. In order to simplify the displacement of the chain, the running surfaces comprise longitudinal slots that are arranged at a distance from each other and that enable the teeth of the running surface profile to pass through, the flanges (17, 18) between the longitudinal slots cover the guide grooves on the side facing the other strand such that the teeth of the rollers of the other strand can roll on the flanges.
