Abstract
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.
