Abstract:
1. A mobile crusher comprising: four-caterpillar chassis; a supporting frame; a receiving hopper; an apron conveyor; a crusher/sizer; and an intermediate conveyor, wherein: the four-caterpillar chassis comprises a first longitudinal caterpillar chassis and a second longitudinal caterpillar chassis under the receiving hopper and a third longitudinal caterpillar chassis and a fourth longitudinal caterpillar chassis under the intermediate conveyor; under a feed side for the material to be crushed, the supporting frame is provided with a crossbeam, at which the first longitudinal caterpillar chassis and the second longitudinal caterpillar chassis under the receiving hopper are mounted via a long caterpillar axle or two short caterpillar axles, on the outside, wherein said receiving hopper is located between said first longitudinal caterpillar chassis and said second longitudinal caterpillar chassis; the first longitudinal caterpillar chassis and the second longitudinal caterpillar chassis under the receiving hopper are not directionally controlled; the third longitudinal caterpillar chassis and the fourth longitudinal chassis under the intermediate conveyor is controlled like a two-caterpillar chassis; the four-caterpillar chassis forms a static defined three-point support with a support ball between the third longitudinal caterpillar chassis and the fourth longitudinal caterpillar chassis under the intermediate conveyor and the supporting frame; and each of the first longitudinal caterpillar chassis and the second longitudinal caterpillar chassis under the receiving hopper and the third longitudinal caterpillar chassis and the fourth longitudinal caterpillar chassis under the intermediate conveyor are dimensioned, such that the mobile crusher can be displaced with full load capacity in the receiving hopper, apron conveyor, crusher/sizer and intermediate conveyor.
