Abstract
Le dispositif, qui est monté entre les semelles de cadres de soutènement voisins, comporte deux barres de guidage, écartées latéralement l'une de l'autre, et deux vérins de marche, prévus au-dessus de ces barres, lesquelles sont reliées aux extrémités antérieures par une tete. A distance à l'arrière de celle-ci, les barres sont reliées par un pont, que les vérins de marche attaquent par leurs tiges de piston. A distance à l'arrière du pont, les vérins de marche sont reliés aux semelles par des consoles de liaison qui présentent des ouvertures de guidage pour le guidage des barres.
