The invention relates to an energy transmission chain for guiding tubes, cables or the like between two connecting points with variable vertical distance. The chain comprises links with two lateral parts that can be interconnected by means of at least one transverse pin. The adjacent links of the chain can pivot in relation to each other in an articulated manner on a plane forming a curved area. In order to provide an energy transmission chain that can be inserted in-between the two vertically variable connecting points while preventing the energy transmission chain from sagging below the lower connecting point when its position is moved vertically upwards, the links (3a) of the chain are interspaced forming areas (6, 7) with opposite radii of curvature. Substantially rigid areas (5) are provided in-between the U-bending areas (6, 7) of the energy transmission chain (3). The rigid areas (5) can be configured in such a way that opposite lateral articulated areas of a pair of adjacent links (3a) can be U-bent in the opposite direction. The invention further relates to a system consisting of a consumer and a supplier, wherein the inventive energy transmission chain is provided between their connecting points. |
