Abstract (en)
[origin: JPH02120461A] PURPOSE: To efficiently achieve both functions of crushing and shearing by forming a shearing machine of a fixed arm and one arm of a crusher, and composing them in such a way that the shearing machine is opened to the utmost when the crusher is closed to the utmost. CONSTITUTION: On a frame 1, both crusher forming members and shearing members are rotatably supported, and both arms 4, 5 of a crusher are driven to be opened/closed by a double acting jack 12. A shearing machine is composed of a fixed arm 14 and one arm 5 of the crusher. The shearing machine is opened to the utmost when the crusher is closed to the utmost, and after a metal reinforcement or the like is engaged in it, the crusher is opened, when the shearing machine is closed, so the metal reinforcement or the like is sheared. Next, a concrete piece or the like is engaged in the crusher as it is opened, and the crusher is closed to crush the concrete piece or the like.
