Abstract
A system for controlling a stability of a milling machine is disclosed. The system includes a frame having a first slope and a leg coupled to the frame. The leg extends and retracts along a length thereof with respect to the frame. The system includes a controller to determine the first slope and to actuate the leg if the first slope is greater than a first predetermined slope.
Claims20
A system for controlling a stability of a milling machine, the system comprising:
- a frame;
- a plurality of legs extending between the frame and a ground surface, each leg of the plurality of legs being configured to extend and retract along a length thereof with respect to the frame;
- and
- a controller configured to:
- determine a first slope of the frame, the first slope being indicative of an inclination of the milling machine with respect to the ground surface;
- and
- actuate one or more legs of the plurality of legs to decrease the inclination of the milling machine based on a comparison of the first slope to a first predetermined slope, wherein the first predetermined slope is indicative of a stability limit of the milling machine.
4 more elements
A milling machine comprising:
- a frame;
- a rotor coupled to the frame;
- and
- a first length adjustable leg coupled to the frame;
- a second length adjustable leg coupled to the frame;
- a third length adjustable leg coupled to the frame;
- a fourth length adjustable leg coupled to the frame;
- and
- a controller configured to:
- determine an inclination of the frame with respect to a ground surface;
- and
- actuate an actuatable leg to decrease the inclination based on a comparison of the determined inclination to a predetermined stability limit of the milling machine, wherein the actuatable leg is at least one of the first length adjustable leg, the second length adjustable leg, the third length adjustable leg, and the fourth length adjustable leg.
9 more elements
A method of controlling a stability of a milling machine comprising:
- moving a ground engaging member of the milling machine over a ground surface, wherein the ground engaging member is coupled to a frame of the milling machine by a leg;
- determining a first slope of the frame, wherein the first slope is indicative of an inclination of the milling machine with respect to the ground surface;
- and
- actuating the leg to decrease the inclination of the milling machine based on a comparison of the first slope to a first predetermined slope, wherein the first predetermined slope is indicative of a stability limit of the milling machine and is a function of a size of the milling machine.
