Mobile bulk material processing machine with demountable hanging assembly

A mobile bulk material processing apparatus comprising:

• a mainframe having endless tracks or wheels arranged to move the apparatus;
• a hanging assembly having at least one material processing unit and a carrier frame, the carrier frame being suspended from the mainframe via at least one support structure and including a plurality of support legs, the material processing unit including at least one screen and the hanging assembly further includes a discharge conveyor mounted below the screen;
• a plurality of first couplings provided at the support structure and a plurality of complementary second couplings provided at the hanging assembly to releasably engage the first couplings to suspend the hanging assembly at the mainframe;
• a plurality of power operated actuators acting on the first and/or second couplings and powered by a motor to move at least one of the first and second couplings relative to one another to provide powered engagement and disengagement between the first and second couplings and arranged to connect and disconnect the hanging assembly from the mainframe;
• and
• at least one telescopic arm on the hanging assembly mounted to extend from the carrier frame, the at least one telescopic arm including one of the second couplings, wherein the at least one telescopic arm is coupled to a respective power operated actuator to move the second coupling to provide powered engagement and disengagement of the hanging assembly with the mainframe to move the hanging assembly between a first position where the hanging assembly is connected to the mainframe and a second position wherein the hanging assembly is disengaged from the mainframe such that the hanging assembly is a free standing unit supported on the ground by the support legs.
