Abstract
An energy conducting chain for guiding of transmission lines between a moveable consumer and a stationary terminal with divisible stays comprising at least two belts with flattened cross-section and rounded narrow sides as well as separation stays arranged between the belts. The upper and lower ends of the separation stays have beveled recesses provided with undercuts, so that the belts after insertion in the recesses are braced or deformed in a force-locked manner and positively without slipping with the separation stays by twisting the belts about their longitudinal axes, respectively. The belts have threaded bores in their ends in which screws passing through the chain links can be screwed. Reinforcement plates are inserted between the belts and the links of the chain.
