Abstract

Le dispositif comporte un outil 13 monté pivotant en bout d'un bras 3 relié au châssis 1 d'un véhicule par un quadrilatère déformable comprenant en outre une bielle supérieur longue 4 et une bielle inférieure courte 5 articulées sur ledit châssis autour d'axes 6, 7 dont la distance est plus grande que celle des axes 8, 9 autour desquels lesdites bielles sont articulées sur ledit bras, un vérin de relevage 10 manoeuvrant le bras relativement à ce bras. Suivant l'invention, un vérin doseur 25 est interposé entre deux quelconques des éléments constituant le quadrilatère déformable et les chambres de ce vérin doseur sont, dans la position neutre d'un distributeur de fluide, montées en circuit fermé avec les chambres conjuguées du vérin de basculement. Ce dispositif est applicable à la manutention de charges diverses en conservant automatiquement leur assiette affichée à l'origine de la manoeuvre.
