摘要： An energy saving device for a hydraulic elevator is provided to obtain energy reduction effect by storing potential energy generated when an elevator rises in a storage battery and using the stored electricity when the elevator re-rises. An energy saving device for a hydraulic elevator comprises a hydraulic cylinder(5), a hydraulic power unit(2), and an energy reduction unit(3) and a control unit(1). The hydraulic cylinder ascends and descends an elevator car. The hydraulic power unit comprises an electric motor(2a), a hydraulic pump(2b), a control valve(2c) and a first valve(2d). The control valve controls the amount of the hydraulic energy generated in the hydraulic pump. The first valve delivers hydraulic energy to the hydraulic cylinder or blocks the hydraulic energy. The energy reduction unit comprises a second valve(3a), a hydraulic motor(3b), a gear(3c), a generator(3d), and a storage battery(3e). The second valve delivers or blocks the hydraulic energy generated in the hydraulic cylinder through a hydraulic pipe(4). The generator generates the electrical energy with the rotation of the gear. The storage battery stores the energy generated in the generator. The control unit controls the hydraulic power unit and the energy reduction unit and supplies the power.
