A hydraulic drive system consists of a first partial system I and a second partial system II. Each partial system has a pump regulated by the stream required (1,9) and a hydraulic energy consumer connected to its output line (2,10). Load pressure lines (7,13) that sense the maximum load pressure are also provided in each partial system I and II; they are connected with the required flow regulators (8,14) of the pumps (1,9). A coupling device III is provided for connecting the feed lines (2,10) and the load pressure lines (7,13) of the two partial systems I and II. The coupling device III can be switched as a function of a consumer designed for driving and is connected with a circuit logic IV that supervises the driving of this consumer. The circuit logic consists of a NAND (not-and-) element (19) and an UND (and-) element (22).
