Each part has partial segment assemblies (5, 6) with three partial segments (7, 9), where the boom is designed in a movable manner from a large working width to a short transport width when two of the segments are connected with one another in a displaceable manner. The partial segments are arranged axially parallel and height-identical to one another in a displaceable manner.</p> |
