Disclosed is a cable drag chain (1) for guiding hoses, cables and the like, comprising a number of chain links that are hingedly interlinked and are formed by parallel lateral link plates (11, 12) and crosspieces (21) connecting the lateral link plates, the respective lateral link plates being linked to form parallel lateral link plate strings. The lateral link plates can pivot relative to one another about a pivot axis that is common to two adjacent lateral link plates. The cable drag chain (1) can move in such a way as to form a loop having an upper strand, a lower strand, and a deflection zone connecting the two strands, thus defining an inner face and an outer face of the chain links in relation to the loop. The upper strand lies on the lower strand in such a way as to at least partially touch the inner faces of chain links. At least some of the chain links are provided with rollers (16) which are inserted in the lateral link plates, are exposed on the inner face, and can roll off a running surface formed by the narrow faces of the lateral link plates (11, 12) of the opposite strand in the tight state of the chain, the lateral link plates of each lateral link plate string being formed by alternating inner link plates (14) and outer link plates (11, 12). At least some of the outer link plates are provided with rollers (16), and only the inner link plates have stops which delimit the pivot angle between adjoining link plates. |
