    • 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).
