Energy Chain and Storage Unit for an Energy Chain

An energy chain (5) for receiving and guiding energy and/or communication cables, the energy chain having chain links pivotably adjoining one another in the longitudinal direction, wherein the chain links comprise in each case two side parts lying opposite one another in a transverse direction (q) relative to the longitudinal direction (I) and at least some of the chain links have cross members connecting their side parts, wherein the energy chain (1) includes several portions which are each arranged in the form of two strands (7, 8) connected to one another by a deflection region (6) extending about a deflection arc, wherein the energy chain (1) is movable about the deflection arc, wherein each deflection region (6) of the several portions is guided on its inner face and its outer face by guide elements (10) extending an arc-shaped manner about the respective axis of the deflection arc.
