Abstract

La présente invention concerne un dispositif de pose à distance d'étançons hydrauliques utilisés dans les travaux miniers. Ce dispositif est caractérisé en ce qu'il comporte, en combinaison, une machine de chantier mobile 2 pourvue d'un bras extensible 3, une source de fluide hydraulique sous pression 5 portée par la machine, une canalisation flexible 6 reliant la source de fluide sous pression à l'orifice d'entrée 7 de l'étançon devant être posé, et des moyens 18, 19 prévus sur chaque étançon pour permettre la prise de ce dernier par le bras extensible 3 de la machine et sa mise en place en position verticale appropriée.
