Abstract

L'invention concerne un dispositif (10) pour actionner un cache anticontamination (18) sur une console de machine (112). Le dispositif (10) comprend un premier cylindre de transition (14) monté sur la console de machine (112) et connecté au cache anticontamination (18), un circuit de transition (16) connecté au premier cylindre de transition (14) afin de transmettre une pression hydraulique au premier cylindre de transition (14), et un capteur de transition (12) couplé au circuit de transition (16) afin de commander la transmission de pression hydraulique vers le premier cylindre de transition (14). L'activation du capteur de transition (12) permet à la transmission de pression hydraulique d'actionner le premier cylindre de transition (14) afin d'assurer la transition du cache anticontamination (18) d'une position fermée à une position ouverte.
