The upper panel of a tailgate assembly is moved in a downward and rearward convexly curved path between an upward and forward position and a rearward and lowered position and the lower panel is rotated forwardly and rearwardly with respect to the upper panel. Linkages are included in the tailgate assembly to provide this movement. A lower surface of the fixed panel may have an upwardly curved lower surface which imparts a forward direction of movement to refuse which is packed against it. The upper panel may have a curved forward surface in close proximity to a rearward surface of the fixed panel. During movement of the upper panel, the rearward surface of the fixed panel removes refuse from the curved forward surface. The upper panel is tilted as it moves and during its upward movement the lower portion of the upper panel is tilted forwardly. This imparts a forward movement to refuse which is moved through the opening into the storage body. The hopper may include a vertically inclined forward packing surface so that refuse is packed between the curved packing surface and the vertically inclined forward packing surface of the hopper. The hopper may include a straight rearward wall portion with the packing panel having a narrowed lower edge. During its movement into the hopper, the packing panel may be moved so that its narrowed lower edge is in contiguous relation to the straight rearward wall portion of the hopper. The packing panel may include one or more upstanding ribs on its curved packing surface which provide a reduced area for application of high localized pressures to refuse contacted by a rib. |
