Abstract

La présente invention concerne une niveleuse motorisée (100) avec un ensemble plaque de moule de différentes longueurs (L1, L2), l'ensemble plaque de moule comprenant une combinaison de lames d'une pluralité de lames interchangeables (3, 4) montées sur le bord opérationnel (6) d'une plaque de moule (1) et un support de bord respectif (2) monté sur les bords latéraux (7) de la plaque de moule. La plaque de moule et les lames interchangeables ont des longueurs de lame prédéfinies différentes pour régler la longueur fonctionnelle globale (L) de l'ensemble plaque de moule selon l'application prévue de la niveleuse motorisée. Une extrémité de bout d'extension respective (5) est également montée en correspondance de l'un ou de l'autre des bords latéraux de la plaque de moule pour correspondre à la longueur totale (L) de la combinaison de lames de lames interchangeables (3, 4) montées sur celui-ci. La plaque de moule (1) est réalisée sans aucune menuiserie en correspondance de son point de connexion avec les bouts d'extrémité d'extension (7).
