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.
