Abstract (en)
The system (10) has two pumping units (13', 13'') and two split control blocks (15', 15'') to supply a hydraulic load of a crane with a hydraulic medium. One of the pumping units is connected to one of the split control blocks and driven by hydraulic pressure. The other pumping unit is connected to the other split control block and driven by another hydraulic pressure. A valve unit (50) is arranged between the split control blocks. The split control blocks are hydraulically connected to and disconnected from the valve unit.
