<p>A support structure (10) for slidably mounting an input hopper (13) for movement between a raised operative position and a lower inoperative transport position on a screening apparatus (12) for screening bulk material, in which the structure (10) comprises:
an input hopper (13) having a base frame (14, 15);
a ramp (17) on which the base frame (14, 15) is slidably mounted for movement of the hopper (13) between the raised operative position and the inoperative transport position, said ramp (17) being adapted to be mounted (19) on the chassis (11) at its upper end;
slide blocks (16) engageable with the base frame (14) to support the slidable movement of the input hopper (13) along the ramp (17); and
mounting brackets (26) on which the slide blocks (16) are mounted, and also adapted to be mounted on the chassis (11).</p> |
