Abstract: A construction having holder means for supporting and guiding at least one flexible energy-transferring line. The chain construction being attached at one end thereof to a connecting point and at its other end to an energy-consuming or energy-producing apparatus capable of moving in the longitudinal direction of the line. The holder means comprising line support means arranged to co-act with parallel links, adjacent ones of said links being joined together in a manner such that said links can pivot through a pre-determined angle. Each link is provided with a support surface, said surfaces being mutually arranged to so as to lie in one and the same plane when the holder means are oriented in one and the same plane. At pre-determined links there are provided support wheels, the peripheral surfaces of which wheels extend over adjacent support surfaces.
