<p>A loadbearing structure for heavy vehicles, e.g. a freight vehicle, incorporates a box-shaped hollow unit (10) extending in the longitudinal direction of the vehicle. Wall elements (12, 14, 16, 18) of thin wall thickness are connected to one another to form the box-shaped unit (10). The invention provides a loadbearing structure (2) for heavy vehicles which is many times more rigid than conventional structures but is nevertheless of relatively low weight and is relatively easy and inexpensive to manufacture. The present invention also relates to a process for manufacturing a loadbearing structure for heavy vehicles.</p> |
