TIPPER ASSEMBLY

A tipper assembly (200) comprises a chassis (210) having a first chassis linkage point (211); a body (220) pivotally attached to the chassis about a body pivot axis (222), the body being pivotable between a lowered position and a raised position; a tailgate (230) moveable between a closed position in which the tailgate is arranged across an end opening (221 ) of the body and an open position in which the tailgate is pivoted away from the end opening; and a first tailgate lift assembly configured to lift the tailgate from the closed position to the open position on movement of the body from the lowered position to the raised position. The first tailgate lift assembly (250) comprises: a first arm (240) having a tailgate end fixedly attached to the tailgate and a first arm linkage point (242), the first arm being pivotally attached to the body about an arm pivot axis (241), the arm pivot axis being arranged between the tailgate end and the first arm linkage point; and a first linkage assembly connecting the first arm linkage point to the first chassis linkage point, the first linkage assembly comprising an arm link (251) and a rapid opening assembly, the rapid opening assembly having a first end attached to the body or the chassis and a second end attached to an intermediate portion (253) of the arm link. The rapid opening assembly is configured to create a v-shape in the arm link, drawing the first arm linkage point closer to the first chassis linkage point on rotation of the body about the body pivot axis from the lowered to the raised position. Ensemble benne (200) comprenant un châssis (210) comportant un premier point de couplage de châssis (211) ; un corps (220) fixé de manière pivotante au châssis autour d'un axe de pivotement de corps (222), le corps pouvant pivoter entre une position abaissée et une position relevée ; un panneau arrière (230) mobile entre une position fermée dans laquelle le panneau arrière est disposé en travers d'une ouverture d'extrémité (221) du corps et une position ouverte dans laquelle le panneau arrière est pivoté à l'opposé de l'ouverture d'extrémité ; et un premier ensemble de levage de panneau arrière conçu pour soulever le panneau arrière de la position fermée à la position ouverte lors du passage du corps de la position abaissée à la position relevée. Le premier ensemble de levage de panneau arrière (250) comprend : un premier bras (240) comportant une extrémité de panneau arrière fixée à demeure au panneau arrière et à
