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

Method for making a skip body with a concave cross section

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.
