<p>A crusher capable of effectively crushing a building structure, shearing iron reinforcing rods, etc., smashing the crushed scraps into pieces, and collecting and carrying an elongated object. A pair of arms (2a, 2b) are driven to open and close for crushing and shearing the object. A front end of each of the pair of arms is divided into a plurality of fingers to which claws (7a, 7a', 7b) are respectively attached. Only the central claw (7a') is inwardly directed by a greater angle as compared with the other claws (7a, 7b). Each arms has a shearing blade (10a, 10b) for shearing an iron reinforcing rod, an iron frame, etc. in the vicinity of the pivoted portion, and also through holes (11) in the central portion. Weight of the arms (2a, 2b) and an arm support (3) are balanced with respect to the central axis of rotation of the arm support (3). The central claw (7a') gives a concentrated stress to the building structure to cause cracks when the arms (2a, 2b) are closed, thereafter the object is squashed out by all of the claws (7a, 7a', 7b). Concrete scraps are smashed by the central portions of the arms and flow out from the through holes. <IMAGE></p> |
