Definitions
- the invention enables a variable adaptation of the speed of the engine, which is advantageously a diesel engine, depending on the hydraulic power currently required in the respective work phase.
- the volume flow conveyed to the hydraulic power generation unit or the hydraulic pumps, which is proportional to the drive speed, is adjusted in accordance with the required power.
- the reduced volume flow reduces throttling and power losses, and the engine operates within its operating map in the area of better efficiency.
- the fixed cyclical sequence of an actuation sequence comprises a number of cycle phases which correspond to an operation of the Machine are assigned, preferably comprising the several cycle phases of the digging, digging, turning, lifting and turning, unloading, swiveling back, driving and / or work preparation and each cycle phase is assigned a respective target engine speed.
