STABILIZATION SYSTEM FOR A MINING MACHINE
First Claim
Patent Images
1. A mining machine comprising:
- a frame;
a cutting head moveably coupled to the frame; and
a first actuator for stabilizing the frame relative to a mine surface, the first actuator being coupled to the frame and including a first end extendable in a first direction to engage the mine surface, the operation of the first actuator being automatically controlled based on measurements of a time required for the first actuator to extend to a position such that at least one indicator of a force between the first actuator and the mine surface reaches a predetermined value.

Abstract
A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.

19. A method for stabilizing a mining machine relative to a first mine surface and a second mine surface, the method comprising:
-
extending a first actuator toward the first mine surface until at least one indicator of the force between the first actuator and the first mine surface reaches a predetermined value; retracting the first actuator by a first predetermined distance; extending the first actuator by the first predetermined distance plus an offset distance; extending a second actuator toward the second mine surface until at least one indicator of the force between the second actuator and the second mine surface reaches a predetermined value; retracting the second actuator by a second predetermined distance; and extending the second actuator by the second predetermined distance plus an offset distance. - View Dependent Claims (20, 21, 22, 23, 24, 25)
