An energy chain and storage unit for an energy chain (1) has a first chain portion (3) and a second chain portion (5), wherein the chain links (2) of the first chain portion and the chain links (4) of the second chain portion are connected to one another in a pivotable manner and comprise in each case two side parts (6, 7), which are located opposite one another in a transverse direction (q) in relation to the longitudinal direction (l) of the energy chain and have upper and lower narrow surfaces (8), which are oriented perpendicularly to the transverse direction (q) and to the longitudinal direction (l), wherein at least some of the chain links (2) of the first chain portion (3) have guide elements (12), which project outwards in the transverse direction (q) from the side parts (6, 7) of the chain links and are intended for guiding on guide tracks (35), which are arranged on the outside of the side parts of the chain links, and at least some of the chain links (4) of the second chain portion (5) have roller elements (13) or sliding elements (14), which project beyond the upper or the lower narrow surfaces (8) of the side parts (6, 7) of the chain links and can respectively roll or slide on a region which is located opposite said narrow surfaces (8) and establishes contact with the energy chain (1).
An energy chain (1) with a first chain portion (3) having several first chain links (2) and a second chain portion (5) having several second chain links (4), wherein the first and second chain links (2, 4) of the two chain portions (3, 5) are pivotably connected to one another and comprise in each case two side parts (6, 7), which lie opposite one another in a transverse direction (q) relative to the longitudinal direction (I) of the energy chain (1) and which have upper and lower narrow surfaces (8) facing perpendicularly to the transverse direction (q) and to the longitudinal direction (l), wherein at least some of the first and second chain links (2, 4) have cross members (9) connecting their side parts (6, 7), wherein at least some of the first chain links (2) of the first chain portion (3) have guide elements (12), which project outwards from their side parts (6, 7) in the transverse direction (q), for guiding the first chain links (2) against or on guide tracks (35) which can be arranged outside their side parts (6, 7), and at least some of the second chain links (4) of the second chain portion (5) have roller elements (13) or sliding elements (14), which project over the upper or lower narrow surfaces (8) of their side parts (6, 7) and can roll or slide on a region which lies opposite these narrow surfaces (8) and contacts the energy chain (1).
