Abstract
The present application relates to a loading unit and/or lifting unit, in particular a reach stacker, comprising one or more pick-ups for the detection of at least one operating parameter influencing the standing safety of the unit and comprising a calculating unit in communication with the pick-up(s) which has means by means of which a maximum permitted value of an operating parameter of the loading unit and/or lifting unit for the ensuring of the standing safety is determined in dependence on one or more of the detected operating parameters.
Claims23
A loading or lifting unit, comprising:
- one or more pick-ups for detecting an actual steering movement and at least one operating parameter influencing a standing safety of the loading or lifting unit;
- and
- a calculating unit in communication with the one or more pick-ups, configured to determine a maximum permitted value of the steering movement in dependence on the at least one operating parameter detected, and further configured to preclude the steering movement from exceeding the maximum permitted value to improve the standing safety.
A loading or lifting unit controlled by an operator, comprising:
- one or more pick-ups configured to detect an actual steering movement and at least one operating parameter influencing a standing stability of the loading or lifting unit;
- and
- an electronic controller configured to determine a maximum permitted value of the steering movement, and to automatically adjust the steering movement to preclude the steering movement from exceeding the maximum permitted value, and in dependence on the at least one operating parameter detected, to improve the standing stability of the loading or lifting unit.
A method for operating a loading or lifting unit controlled by an operator, the method comprising:
- measuring an actual steering movement and at least one operating parameter influencing a standing stability of the loading or lifting unit via one or more pick-ups;
- receiving in an electronic controller the at least one operating parameter measure;
- determining a maximum permitted value of the steering movement;
- precluding the steering movement from exceeding the maximum permitted value;
- and
- adjusting at least one operating parameter other than the steering movement in dependence on the at least one operating parameter received so that the maximum permitted value of the steering movement is not exceeded.
A loading or lifting unit, comprising:
- one or more pick-ups for of detecting an actual steering movement and at least one operating parameter influencing a standing safety of the loading or lifting unit;
- and
- a calculating unit in communication with the one or more pick-ups and configured to determine a maximum permitted value of the steering movement in dependence on the at least one operating parameter detected, and further configured to preclude the steering movement from exceeding the maximum permitted value to improve the standing safety;
- wherein means are provided to change an operating parameter other than the steering movement to preclude the steering movement from exceeding the maximum permitted value of the steering movement;
- and
- wherein the operating parameter other than the steering movement includes lifting load, a working radius, a load height, a boom inclination, or an inclination of the loading or lifting unit.
A loading or lifting unit, comprising:
- one or more pick-ups for detecting an actual steering movement and at least one operating parameter influencing a standing safety of the loading or lifting unit;
- and
- a calculating unit in communication with the one or more pick-ups, configured to determine a maximum permitted value of the steering movement in dependence on the at least one operating parameter detected, and further configured to preclude the steering movement from exceeding the maximum permitted value to improve the standing safety;
- wherein changing the steering movement is only possible to an extent that the maximum permitted value of the steering movement is not exceeded when none of
- a lifting load, a working radius, a load height, a boom inclination, and an inclination of the loading or lifting unit are changed.
