Abstract (en)
[origin: US4903903A] A mobile crushing plant has an elongated frame with a front end portion connectable to a towing vehicle and a rear end portion supporting a comminuting machine which receives material to be crushed from a feeding unit having an inlet above the front end portion of the frame. When the plant is in use, the front end portion is detached from the towing vehicle and a first set of jacks in front of a pair of normally ground-contacting wheels is lowered into contact with the ground. A second set of jacks behind the wheels is then extended to lift the rear end portion by pivoting the frame about the lower end of the first set of jacks so that the inlet of the feeding unit is moved nearer to the ground and the comminuting machine is lifted above and away from the ground. A portion of the feeding unit is substantially horizontal when the front end portion of the frame is attached to the vehicle or when the crushing plant is in use.
