Abstract
Provided is a working machine capable of regenerating and utilizing surplus energy. The working machine related to the present invention is provided with a branching flow path () through which hydraulic oil flows between a hydraulic actuator () and a hydraulic pump-motor (), an accumulator () arranged in the branching flow path, a first opening/closing valve () arranged between the accumulator and the hydraulic pump-motor, and a second opening/closing valve () arranged between the accumulator and the hydraulic actuator. A control device () selectively introduces the hydraulic oil from the hydraulic actuator and the hydraulic oil from the hydraulic pump-motor to the accumulator and accumulates the same by controlling opening/closing of the first opening/closing valve and the second opening/closing valve.
