Abstract

The invention relates to a method of operating a mobile work machine with a ground pressure limitation and to a corresponding work machine. A maximum permitted ground pressure is compared with an actually present ground pressure.

Claims (25)

1. A method of operating a mobile work machine with a ground pressure limitation, comprising the steps:

detecting a current unit load of the mobile work machine via sensors;

determining a maximum permitted ground pressure;

calculating an actual ground pressure based on the current unit load;

comparing the calculated actual ground pressure with the maximum permitted ground pressure; and

reporting the comparison result to an operator of the mobile work machine via a visualization and/or stopping a movement of the mobile work machine that increases the ground pressure on an exceeding a limit value of the actual ground pressure.

2. The method in accordance with claim 1 , wherein a manual input by the operator and/or an automatic measurement of the maximum permitted ground pressure is carried out to determine the maximum permitted ground pressure.

3. The method in accordance with claim 2 , wherein a setting of a unit configuration of the mobile work machine is carried out by the operator.

4. The method in accordance with claim 1 , wherein a setting of a unit configuration of the mobile work machine is carried out by the operator, the setting of the unit configuration of the mobile work machine comprises a setting of a ballast and/or of a pole length.

5. The method in accordance with claim 4 , wherein a detection of a geometry of the mobile work machine is carried out, the geometry of the mobile work machine including one or more of outreach and tilt of the mobile work machine.

6. The method in accordance with claim 4 , wherein a calculation of a load of the mobile work machine is carried out.

7. The method in accordance with claim 1 , wherein a detection of a geometry of the mobile work machine is carried out, the geometry of the mobile work machine including one or more of outreach and tilt of the mobile work machine.

8. The method in accordance with claim 7 , wherein a setting of a unit configuration of the mobile work machine comprises a setting of a ballast and/or of a pole length of the mobile work machine.

9. The method in accordance with claim 1 , wherein a detection of a load of the mobile work machine is carried out.

10. The method in accordance with claim 9 , wherein a setting of a unit configuration of the mobile work machine comprises a setting of a ballast and/or of a pole length of the mobile work machine.

11. The method in accordance with claim 1 , wherein a calculation of a load of the mobile work machine is carried out.

12. The method in accordance with claim 11 , wherein a setting of a unit configuration of the mobile work machine comprises a setting of a ballast and/or of a pole length of the mobile work machine.

13. A work machine having an apparatus for carrying out a method, comprising the steps:

detecting a current unit load of the work machine via sensors;

determining a maximum permitted ground pressure;

calculating an actual ground pressure based on the current unit load;

comparing the calculated actual ground pressure with the maximum permitted ground pressure; and

reporting the comparison result to an operator of the work machine and/or stopping a movement of the work machine that increases the ground pressure on an exceeding a limit value of the actual ground pressure.

14. The work machine in accordance with claim 13 , wherein a sensor apparatus is provided for an automatic measurement of the maximum permitted ground pressure.

15. The work machine in accordance with claim 13 , wherein the work machine is a pile driver and/or a drill.
