The invention concerns a hopper (10) comprising a hopper body (12) having side and end walls (14 and 16) extending downwardly to a lower edge (54). In addition, there is a hopper bottom (26) having a chassis frame (28) carrying rail wheels (30) on which the hopper runs on a rail track. The hopper bottom (26) is connected pivotally to the hopper body (12) for movement relative to the hopper body between an open position in which the bottom has moved pivotally away from the hopper body to allow gravitational discharge of the hopper contents and a closed position in which the chassis frame of the bottom and the lower edge of the hopper body locate one inside the other. |
