Abstract: A lifting mechanism is disclosed which is operated hydraulically and is configured to be mounted or used on a mobile working machine. The lifting mechanism or its hydraulics have a relieving pressure limiting valve which can be regulated as a function of the ground profile. For this purpose, a directly or indirectly measuring sensor arrangement is provided. Furthermore, a method is disclosed which serves for regulating a relieving pressure of a lifting mechanism of a mobile working machine. The method has the following steps (i) detection of the ground profile via a sensor arrangement, and (ii) limitation of the relieving pressure of a relieving line by setting an opening pressure of an electronically activatable proportional relieving pressure limiting valve via a control unit as a function of signals from the sensor arrangement.
