摘要： A drag chain comprising a plurality of chain links connected to one another in an articulated manner for guiding cables between two connection points, wherein opposing link plates and crosspieces of the chain links form a receiving space for the at least one cable, wherein the drag chain can be arranged and moved as a structure formed by a lower track, an upper track and a deflection region connecting same, with the upper track being placed on the lower track, and wherein the chain links of the lower track and/or the upper track are or can be fitted with additional elements, e.g. sliding elements, on the side facing the respective other track. The chain has an end-securing part with connection-securing means for securing the end-securing part to a connection point or said chain is secured to a stationary connection point by means of same. At least one wedge-shaped ramp-type element is provided on the end-securing part of the lower track, on the side facing the upper track, said ramp-type element comprising a pointed end and a broad end spaced apart from one another in the longitudinal direction of the chain. The wedge-shaped ramp-type element is or can be arranged on the end-securing part with its longitudinal direction at least substantially parallel to the longitudinal direction of the chain, wherein, in the secured arrangement on the chain, the ramp-type element tapers in the direction leading away from the deflection region and the upper side of the ramp-type element facing the upper track forms a ramp-type surface for the upper track.

摘要： Novel separators, transverse links and transverse bases or compartment bottoms for chain links of energy chains. The separator has a pivotable sidebar wherein the top portion and the bottom portion each have a holding clamp for interacting with the narrow sides of a transverse link, the top portion being connected to the first side bar and being detachable and/or pivotable together therewith. The transverse link has a row of teeth protruding at the narrow sides for interlocking with the separators, designed in a manner complementary thereto, and/or a cable-protecting protective layer on the inner face for protecting the guided cables.

摘要： A strain relief device for at least one supply line. The strain relief device can be or is disposed on a line-guiding apparatus for guiding the at least one supply line and has at least one main body, which comprises at least one coupling means for the fastening of the at least one supply line to said coupling means and thus to the strain relief device in such a way that strain is relieved. At least one preferably flexible coupling element is provided, which can be disposed so as to peripherally surround the coupling means and the line to be fixed on the coupling means and which surrounds the line together with the coupling means in the form of a loop. There are fastening means on the main body for fastening the main body to the strain relief device in such a way that tensile force is absorbed. A guide element having a guide region for the coupling element is provided adjacent to the at least one coupling means. The guide region is designed to guide the coupling element as the coupling element is transferred from a position at a distance from the coupling means to the position of the coupling element in which the coupling element fastens the supply line to the coupling means in such a way that strain is relieved.
