Abstract

La présente invention concerne un outil de travail mobile formant drague hydraulique. Cette drague se caractérise en ce que sur un bras 5 articulé à la flèche 3 est articulée par l'intermédiaire d'un vérin hydraulique 13, 14 une pièce de jonction 18 sur laquelle est à nouveau articulé un palier 20 portant une vis sans fin 22. Le palier 20 avec la vis 22 peut être entraîné en pivotement au moyen d'un autre vérin hydraulique autour d'un axe d'articulation 19. La vis sans fin 22 est équipée d'une goulotte de transport 24. Cette drague hydraulique peut être utilisée pour creuser des fossés ou pour les combler.
