Abstract

A combination of a tractor unit (10) and a wheeled trailer combination, preferably a mobile screening plant (100), in which the tractor unit (10) has endless tracks (11) to render the combination highly manoeuvrable, and carries an upwardly and downwardly adjustable "fifth wheel coupling" (13) which pivotally connects the forward end (115) of the screening plant (100), the latter having a wheelset (118) at its rear end, and in which the screening plant (100) has an input hopper (114), an elevator (112) for conveying material to be screened from the hopper to a screen box (117), and plant one or more discharge conveyor (121, 123) for discharging screened material to form one or more stockpile of screened material.
