摘要： A device for breaking and crushing reinforced concrete and also shearing off steel bars or the like embedded therein or exposed therefrom after concrete has been torn off. The device comprises in general a frame, a cutter assembly or unit and a hydraulic actuator for operating the cutter assembly. The cutter assembly comprises a stationary cutting blade securely attached to the frame and a movable cutting blade pivotably attached to the frame and operatively coupled to the hydraulic actuator so that the movable cutting blade may move toward and away from the stationary cutting blade. The stationary and movable cutting blades clamp concrete and steel bars or the like embedded therein between them and crush concrete and shear off the steel bars or the like simultaneously as the movable cutting blade is forced to move toward the stationary cutting blade. (Both the stationary and movable cutting blades may be formed with jaws integrally thereof so that the jaws may also crush concrete and/or securely clamp it between them while the cutting blades break and crush concrete and/or shear off the steel bars or the like.)
