<p>The apparatus consists of a parallelepipedal framework whose support face is formed by a series of sections (1) disposed transversely to its largest dimension. At least one section is arranged each meter and a half along the length of the apparatus with a view to imparting to it the necessary rigidity, together with other sections (2) disposed vertically and assembled to the first ones, while on the upper face there are only two sections (5) which determine its largest dimension and serve as rails for a travelling crane which can track along the entire length of the apparatus, so as to make it possible to insert and remove chasses and to replace chassis bodies. <IMAGE></p> |
