Abstract (en)

[origin: EP1857587A1] The hollow section (1) is made from metal sheets (2-6) of thickness (d) which is preferably less than 12 mm. The sheets are precision-cut from plate material. They are subsequently welded together. They are mortised together. Sheet bulkheads (6) are included; these are connected to the sidewalls. They are provided with tenons (14) fitting corresponding mortice openings (15) in the sidewalls, where they are slot-welded in. The bulkheads, at right angles to the longitudinal axis, are spaced apart by 650-990 mm. In a variation, several are arranged at an angle to the longitudinal axis. They may zig-zagged in contact, making a form of internally-trussed angular framework. Adjacent sheets (2, 3) are reinforced by welding-in triangular corner sections. Mountings are attached to end faces of the traverse. The sheets are cut from plate material using a thermal process, especially laser-cutting. Alternatively a non-thermal process is used, such as water-jetting. Plates are straightened after precision cutting. The sheets may be subjected to permanent plastic deformation. A robot conducts the welding process. An independent claim IS INCLUDED FOR the hollow traverse.
