WIPO Patent Application WO/1996/023944

Kind Code:

A1

Abstract:

A crushing device capable of efficiently performing crushing of a structure, cutting of reinforcing bars or the like, secondary crushing of crushed fragments and collection and transfer of lengthy articles. An object is crushed and sheared by drivingly opening and closing a pair of arms (2a, 2b). Tip ends of the pair of arms are divided into a plurality of fingers, each of which mounts thereto a claw (7a, 7a', 7b). Only a claw (7a') at the center of one of the arms (2a) faces further inward than the other claws (7a). Shearing blades (10a, 10b) for shearing reinforcing bars and reinforce frames or the like are provided in the vicinity of pivots of the respective arms, and through holes (11) are provided in intermediate portions of the arms. Weights of the arms (2a, 2b) and an arm support (3) are balanced with respect to an axis of rotation of the arm support (3). After the arms (2a, 2b) are closed and the central claw (7a') applies a concentrated stress on a structure to cause therein crack, all the claws (7a, 7a', 7b) collapse the structure. Concrete fragments having been clamped and broken into small pieces by the intermediate portions of the arms are discharged from the through holes.
