Jaw crusher for bulky waste and like matter

Jaw crusher for bulky waste and like matter, comprising two groups of jaws adapted to be movable towards and away from each other, the jaws within each group being spaced at intervals corresponding to the width of the jaws of the opposite group so that the jaws of one group as they move towards the other group travel at least partly into the interspace between the jaws of the opposite group, driving units operatively connected to at least one group of jaws to move them towards the opposite group, means to move at least one of the jaws of at least one respective group relative to the remaining jaws of the same group, said driving units comprising individually actuable driving units for individually operating each jaw of said at least one group of jaws, sensing means for sensing power exerted by said driving units, a programmable central unit operatively connected to said sensing means to be actuated thereby in response to a predetermined resistance to a jaw to actuate the driving unit of at least one adjacent jaw to change the relative position of the jaws in said group and produce a counter-directed movement of the jaws resulting in maximum breaking power.
