Abstract: A shear system for processing scrap is provided that includes guiding and catching walls for enhancing the loading of large items into the shear system. A tiltable hopper is provided with an open rear so that very large and long scrap items may be processed. The hopper is tiltable so that scrap items may be loaded with relatively smaller apparatus. The system operates to precrush the scrap material taking advantage of leverage yielded by using pivoting wing and flap crushing surfaces. Crushing forces are essentially relieved prior to shearing to decrease the likelihood of jamming of the shear head. The system is modular and may be shipped to and erected in remote locations where electric power for operating the system is not available. The system includes an enclosed and protected area for the power plant and control station.
