Abstract

In a method for operating a load (4) by means of a hydraulic motor (3) that is supplied with fluid by a pump device (20), a drive shaft (12) is to be associated with the pump device (20) and a speed control of a drive shaft for the load (4) is to be carried out by a speed control of the drive shaft (12) and/or the pump device (20) is to have a constant displacement volume per revolution.
