In a guide channel structure, for instance for an energy transmission chain, designed for fastening on a substructure which, as on a crane with pivotable jib, for example, displays a stationary section and a section pivotable about a first axis of rotation (8), a stationary structural element (6) for fastening on the stationary section of the substructure and a movable structural element (7) for fastening on the pivotable section of the substructure are provided, as well as an intermediate structural element (9) located between the two structural elements (6, 7), which is connected to the movable structural element (7) in a manner permitting pivoting about a second axis of rotation (10), where the parts are coupled by a control device in such a way that, when pivoting the substructure, the movable structural element (7) and the intermediate structural element (9) move past each other. |
