  • Patent number: 5220779
    Abstract: A cable drag chain, for supporting and guiding energy supply cables, hydraulic hoses or the like, connected between a fixed point and a linearly movable body, comprises a series of links flexibly connected together, each link including a pair of opposed link plates fixed in parallel relation by connecting rods to form an interior space communicating with corresponding interior spaces of connecting links. Internal partitioning structure separates the interior space of each link into vertically and laterally related channels for accommodating the cables. Sleeves rotatable in the structure provide rolling contact with cables.
