The utility model relates to a hydraulic control system has the big shortcoming of gyration hydraulic control system energy loss now for solving, the utility model discloses an engineering machine tool auxiliary equipment gyration hydraulic control system constructs, power drive device, gyration motor including the engineering machine tool, its characterized in that still includes two -way variable displacement pump, two hydraulic fluid ports of two -way variable displacement pump respectively through left pipeline and right pipeline correspond with two hydraulic fluid ports of gyration motor are connected, and two -way variable displacement pump's power input shaft is through the output shaft of clutch with the power drive device. The utility model discloses in, forming the loop between variable pump and the gyration motor, auxiliary equipment hydraulic system is the closed system by the open system change, and the system is simpler, the installation of being convenient for, electromagnetic clutch controls t
