The invention discloses a hydraulically driven lift system. A movable bottom plate (5) is mounted at the bottom of a lift car (3), and a hydraulic buffer (6) is mounted under the movable bottom plate (5), and is mounted on the floor of the lift car (3); a storage battery (4) which provides power to the hydraulic buffer (6) is mounted on the roof of the lift car (3). By utilizing the hydraulic buffer (6) to sense acceleration, the hydraulically driven lift system controls the flowing direction of pressure oil in order to decrease the discomfort of the human body caused by acceleration in the period from the failure of the lift to the stopping of the lift by a lift safety system.
