Claim Text:
1. A method for synchronizing a speed of a hydraulic crane drive having at least one hydraulic consumer, which is fed with a variable volumetric rate of flow by way of at least one hydraulic variable displacement pump, comprising: driving the at least one hydraulic variable displacement pump by way of a drive unit of the crane, and controlling a speed of the drive unit and a swashplate angle of said at least one hydraulic variable displacement pump, with at least one of an open loop control and a closed loop control, as a function of a demanded volumetric flow rate for at least one consumer, on the basis of one additional parameter, or both as a function of the demanded volumetric flow rate for the at least one consumer and on the basis of the one additional parameter, by way of a crane control system, wherein the crane control system adjusts, individually and load-dependent, at least one of an acceleration ramp and a deceleration ramp of the speed of the drive unit.
