Self-propelled screening apparatus

摘要

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 provided in or on the superstructure ( 13 ) and arranged to provide motive power to operate the endless tracks ( 12 ) and where the prime mover 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 and the screen box ( 16 ) are arranged on opposite sides of the rotational axis of the superstructure ( 13 ), to provide a stable weight distribution.
