The invention concerns a crusher-jaw for the crushing of stones or blocks with a large mass.The crusher-jaw involves a stationary jaw (2), a moving jaw (3), which extends diagonally upwards from the lower section of the stationary jaw, and a drive mechanism (8, 12) for the moving jaw.The moving jaw, according to the invention, consists of at least one lever (8), whose one end (10) can pivot on the upper section of the moving jaw and whose other end is deployed with a hydraulic cylinder. One end of the lever is driven to describe a circular arc, so that the moving jaw comes to complete a composite movement in a horizontal direction and a downwards direction around the joint area for a support rod (4).<IMAGE> |
