Motor-Hydraulic Scrap Steel Grab has hydraulic power and control system itself, and the hydraulic power system is imported from Europe and USA. The grab uses constant output pump and servo system. The flow of pump can change by itself according to working pressure. When the pressure reaches the max pressure, the flow is almost zero, so it can reduce the overflow, and reduce the temperature rise of oil. The opening and closing is controlled by valves or positive inversion motor which ensures the grab can positive inversion rotate frequently. The grab can be designed as half-close or full-open type with long teeth. The peels of the grab are particular, it is easy to grab scrap steel. The grab has six or eight peels, and each peel is driven by an oil cylinder, so the material won’t leak. The grab has tie-in on the grab and it is easy to connect to the crane.
