ABSTRACT:
A self-propelled stone crusher includes systems designed to operate the various machine functions by remote control (30), for operating on open ground or inside trenches, collecting and crushing rocks and stones which are then unloaded and levelled behind the machine. The chassis (3) of the machine is hinged to a shaft (11) integral with a crawler support structure (5) so that the machine can be tilted to a greater or lesser extent, depending on the lie of the land, and the crusher has a hammer mill (10) at the front, the perimeter of which is formed by a grid consisting of a number of bars (25), the distance between which varies, depending on the required particle size of the crushed material.
