Abstract

L'invention concerne un engin (1) de travail comprenant un châssis (2) mobile déplaçable sur la surface du sol, un bras (3) de levage monté sur le châssis (2) à pivotement autour d’un axe (4) horizontal pour un déplacement en monte et baisse du bras (3), et un coupleur (5) d’accessoire solidarisable à l’extrémité libre du bras (3) par une liaison (6) pivot d’axe parallèle à l’axe (4) de pivotement du bras (3) par rapport au châssis (2). Ledit coupleur (5) comprend une platine (7) présentant une face (8) arrière tournée vers le bras (3) équipée de ladite liaison (6) pivot du coupleur (5) au bras (3) et une face (9) avant opposée. La platine (7) est munie d’une ouverture (10) traversante et la liaison (6) pivot reliant le coupleur (5) au bras (3) est disposée en regard de ladite ouverture (10). Figure pour l’abrégé : Fig. 1
