摘要

The system (1) has a hydraulic pump (2) including a connection (3) connected with a hydraulic consumer (7), and another connection (4) connected with a tank volume (5) and a hydraulic lifting device (20) for lifting a weight (27). The connection (4) is connected with the tank volume via a suction line (6) and a return valve (29). The return valve opens in a direction toward the hydraulic pump and is arranged in the suction line. The hydraulic lifting device is connected with the hydraulic pump by a storage line (19).
