ABSTRACT:
A mobile, portable crushing and screening plant includes a crusher (17), a screening device (31), and a conveyor (46) mounted on the trailer having a main frame (11) and support wheels (21-24). The screening device (31) is hinged for vertical swinging movement between a raised operating position and a lowered transport position. The conveyor mechanism (46) includes an elevating section (95) having a pair of hinged segments (103, 104) which are connected to the elevatable end of the screening device (31) so that both the hinged segments (103, 104) are raised and lowered between their operating and transport positions when the screening device (31) is moved by hydraulic actuators (121, 122) between its operating and transport positions. The main conveyor belt (48) passes rearwardly between the laterally spaced trailer wheels (21, 22 and 23, 24) with the working run being above and the return run being below the transverse wheel axles (73, 74). A receiving chute (47) for the main conveyor belt (48) is disposed rearwardly of the trailer main frame (11) and is mounted on a hinged section (79) of the conveyor (46) which is pivoted to the trailer main frame (11) adjacent the trailer wheels for swinging movement between a lowered operating position and a raised transport position.
