ABSTRACT:
A self-propelled screening apparatus (1) having a chassis (11); a pair of endless tracks (12) supporting the chassis (11); a superstructure (13) rotatably mounted on the chassis (11); a prime mover (19) provided in or on the superstructure (13) and arranged to provide motive power to operate the endless tracks (12) and where the prime mover (19) is rotatable with the superstructure (13); and a screen box (16) mounted on the superstructure (13), also for rotation therewith. The screen box (16) has an input (17) for receiving a supply of bulk material, at least one screen deck for screening the bulk material, and an output for discharging screened material. The prime mover (19) and the screen box (16) are arranged on opposite sides of the rotational axis of the superstructure (13), to provide a stable weight distribution.
