PROBLEM TO BE SOLVED: To crush the mass of reinforced concrete or the like without altering the posture of a crushing machine, and enhance the efficiency of the demolishing work through cutting, attraction, and selective collection of iron bars and the like by disposing magnetic units on the back surface of the crushing part. SOLUTION: A crushing machine 1 attached to the arm distal end of a construction vehicle such as a hydraulic shovel and used for demolishing work or the like is provided with a movable frame 3 via a pin 4 on its main frame 2 for open and close operation by a hydraulic cylinder 5 in order to crush a matter C to be crushed between crush parts 2A, 3A. Then, cutters 13, 14 are set at the base end side of the crush parts 2A, 3A of the crushing machine 1 to render cutting or the like of iron bars possible, and magnetic units 10, 11 are put on the back surface of the crush parts 2A, 3A and magnetization current is applied thereto by magnetic wiring 12. Accordingly, without altering the posture of the crushing machine, the matter C to be crushed is compressed before cutting, attracting, and selective collecting of iron bars, thereby raising the working efficiency of demolishing work. Besides, the magnetic unit 10, 11 are not brought in contact with the matter to be crushed directly. |
