Abstract
A guide channel for receiving and guiding guide chains for energy lines has a bottom that is divided in the longitudinal direction and has a width that is adjustable to varying sizes of guide chains to be guided. The guide channel is assembled from a system of prefabricated parts. Channel sidewalls of varying heights are provided. The bottom is comprised of two profiled carrier elements having a meander-shaped profile that, in the longitudinal direction, are arranged in a mirror-symmetrical arrangement relative to one another in a common horizontal plane. Each profiled carrier element is comprised of three U-shaped profiles. A first and a second one of the U-shaped profiles are open in an upward direction, and a third one of the U-shaped profiles is open in a downward direction. The third U-shaped profile is connected between the first and the second U-shaped profiles. The first U-shaped profile is positioned outwardly relative to the mirror-symmetrical arrangement, and the channel sidewalls are inserted into the first U-shaped profile.
