Abstract: A method for forming a one-piece skip body with a concave cross section from a large metal sheet (1) by imparting an approximate cross section to the sheet using shaping mechanisms (2) is disclosed. According to the method, the approximate cross section is maintained while a sealing plate (10) is secured to one end (9) and a stiffening reinforcement member (13) shaped according to the final cross section is attached to the other end (12). The longitudinal edges are stiffened then the most curved areas are mechanically treated and the shaping mechanisms (2) are released. The method is relevant to skip manufacturers and more generally to builders of utility vehicles.

Abstract: A floorplate element formed from a perforated sheet metal in which the floorplate element has a sequence of raised areas and recessed grooves. The floorplate element has at least one thinner transverse recessed area which results from a compression-pinching of the perforated sheet metal of a bottom surface of the grooves towards an top surface of the raised areas. Each transverse recessed area forms a surface for supporting the floorplate element on a crossbeam of a supporting structure. The invention is suitable for use in commercial vehicles as a loading surface.
