Abstract
The present disclosure relates to a hydraulic system for a crane with at least one hydraulic circuit, which comprises at least one hydraulic consumer, and a constant pressure network, wherein the at least one hydraulic circuit is coupled with the constant pressure network via at least one pressure reducer, whereby a higher volume flow with low pressure as compared to the constant pressure network can be generated in the hydraulic circuit.
