Drag chain

Abstract

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.
