<p>The cab (15) has curved walls, front walls (7a, 13), lateral walls (9a, 9b), and a rear wall (12) welded on a floor (1). The floor and one of the walls are assembled before welding by an assembly of shape concordant units between a lower edge of one of the walls and an external edge of the floor, where the shape concordant units are constituted of tabs (10) and slots (11). The assembly provides a mutual support point that supports the wall with respect to the floor when an external mechanical effort is applied to the wall and the floor.</p> |
