Abstract
On an energy guiding chain for guiding hoses, cables and the like, where the upper strand rests on the lower strand and rollers (5, 6) are provided on at least some chain links of the upper strand and/or the lower strand, which can roll on running surfaces (9, 10) provided on the chain links of the opposite strand and which, on their running surface, display a number of spaced peripheral guide grooves that can be engaged by the crests (13, 14) of the rollers of the opposite strand, it is envisaged, in order to facilitate traversing of the chain, that the running surfaces display spaced longitudinal slits that allow the crests of the roller profile to pass through, where the webs (17, 18) between the longitudinal slits cover the guide grooves on the side facing the other strand, such that the crests of the rollers of the other strand can roll on the webs.
