Abstract

L'invention concerne un procédé servant à renouveler des traverses (3) d'une voie ferrée (4). Des rails (13) sont soulevés des traverses (3) après un desserrage de moyens de fixation (2) de rail, et les traverses (3) sont remplacées. L'invention prévoit que le desserrage des moyens de fixation de rail est effectué de telle manière que les moyens de fixation (2) de rail disposés respectivement de part et d'autre à côté d'un rail (13) sont éloignés les uns des autres au moyen d'un dispositif d'écartement (1) jusqu'à ce qu'un léger espacement entre les moyens de fixation (2) de rail soit plus grand qu'une largeur de patin de rail. L'invention concerne en outre un dispositif servant à mettre en œuvre le procédé.
