<p>A crashing or cutting device comprising a body (6), crushing/cutting jaws(l) making, rotation and attached to the body by means of one or several shafts (5), a first power unit (3) to move said jaws against each other, whereby at least one shaft (5) of jaw (1) is fitted with bearings to rotate in regard both to body (6) and jaw (1) and the said bearings are eccentric among themselves and the device has a second power unit (4) in order to rotate at least one said shaft (5). The second power unit (4) is fitted to press jaws (1) against each other in multiplying the motive force of the second power unit (4) between eccentricity distance (e) of the bearings and by means of a torsion arm longer than said eccentricity distance (e) connected to the shaft, in a situation, where shaft (5) is rotated 180° at the most, and when the first power unit (3) is hydraulically locked or in a position pressing the jaws against each other.</p> |
