Stabilization system for a mining machine
First Claim
Patent Images
1. A mining machine including:
- a frame;
a cutting head supported for movement on the frame;
an actuator for stabilizing the frame relative to a mine surface, the actuator coupled to the frame and including an end extendable in a first direction to engage the mine surface; and
a control system configured to operate the actuator, the control system configured to retract the actuator, for a predetermined amount of time, from a position at which at least one indicator of the force between the actuator and the mine surface satisfies a specified range, and extend the actuator for the predetermined amount of time plus an additional amount of time.

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.

11. A control system for operating at least one stabilization member to engage a support surface, the control system comprising:
-
a sensor configured to detect at least one indicator of a force exerted between an end of the stabilization member and the support surface; and a controller in communication with the sensor, the controller configured to retract the stabilization member, for a predetermined amount of time, from a position at which the at least one indicator of the force between the stabilization member and the support surface satisfies a specified range, the controller further configured to extend the stabilization member for the predetermined amount of time plus an additional amount of time. - View Dependent Claims (12, 13, 14, 15, 16)
