Abstract
An energy drag chain is provided for guiding tubes, cables or the like between two points or connection that can be moved relative to each other. The drag chain comprises a plurality of chain members hinged to one another, each having two lateral flat links and cross members inter-linking the flat links. Such a drag chain provides a sound-damping which does not entail the deposit of dirt on the support or the guide channel, and which can be reliably installed and supplied in a pre-assembled state with a pre-manufactured system. At least in one chain section the chain members are provided with damping devices that comprise a relatively soft material and project on one side. The damping devices can be particularly configured as mushroom plugs.

An energy drag chain for guiding tubes;
- or cables between two connection point movable relative to each other, the drag chain comprising a plurality of chain members hinged to one another, each chain member having two lateral flat links (1, 2) and cross-members (3) inter-linking the flat links the flat links each having a groove (7, 8), the chain having a lower strand attachable to one of the connection points and an upper strand attachable to other of the connection points, the two strands transitioning into one another via a deflection zone, wherein the chain members are provided, at least in one chain section, with damping devices comprising relatively soft material, the damping devices being provided on an outer side of the chain in the deflection zone and projecting from the chain members on the outer side, wherein the damping devices include a top portion (12) that is generally semi-spherical in cross section, each damping device having a foot (13) that engages the corresponding groove on the chain member.
