Abstract

A tipper assembly comprises a chassis having a first chassis linkage point; a body pivotally attached to the chassis about a body pivot axis, the body being pivotable between a lowered position and a raised position; a tailgate moveable between a closed position in which the tailgate is arranged across an end opening 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 comprises: a first arm having a tailgate end fixedly attached to the tailgate and a first arm linkage point, the first arm being pivotally attached to the body about an arm pivot axis, 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 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 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.
