    摘要: The invention relates to a hydraulic drive, comprising a hydraulic cylinder (1), divided into a first operating pressure chamber (4) and a second operating pressure chamber (5), by an operating piston (3). The hydraulic drive further comprises a closed hydraulic circuit (39), with a first hydraulic pump (43), connected to the first operating pressure chamber (4) via a first working line (7), by means of a first connector (10) and to the second operating pressure chamber (5) via a second working line (13), by means of a second connector (12). In addition, an open hydraulic circuit (40) is provided, with a second hydraulic pump (8), connected to the first operating pressure chamber (4), by means of a third connector (11). A fourth connector (14) on the second hydraulic pump (8) is connected to a hydraulic reservoir element (75).
