1. A shuttle car comprising:
- a frame for hauling mined material and supported for movement in a mine;
a drive motor driving a mechanism for moving the shuttle car;
a cable connected to a power source and providing power to the drive motor;
a reel for reeling in and paying out the cable, the reel being rotated by a winding motor;
a sensor for detecting a position of the shuttle car relative to at least one of a hazard and a tie-off point; and
a controller configured to receive the position detected by the sensor, the controller modifying a speed of the drive motor and a speed of the winding motor when the position is within a predetermined distance with respect to one of the hazard and the tie-off point.

Abstract
A device for reducing damage to an electric vehicle powered by a trailing cable, the device including an electric sensor for determining the mobile equipment'"'"'s position relative to a hazard, and an electric controller responsive to the electrical means for operating a motor to change the operation of the electric vehicle to reduce the likelihood of adverse effects to the trailing cable if the electric vehicle'"'"'s position is near the hazard.

9. A system for controlling operation of a mining machine, the mining machine including a frame for hauling mined material, a drive motor, a cable connected to a power source and providing power to the drive motor, a reel for reeling in and paying out the cable, and a winding motor for rotating the reel, the system comprising:
-
a sensor for detecting a position of the mining machine relative to a tie-off point; and a controller configured to receive the position detected by the sensor, the controller modifying a speed of the drive motor and a speed of the winding motor when the position is within a predetermined distance with respect to the tie-off point. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A shuttle car comprising:
-
a frame for hauling mined material and supported for movement in a mine; a drive motor driving a mechanism for moving the shuttle car; a cable connected to a power source and providing power to the drive motor; a reel for reeling in and paying out the cable, the reel being rotated by a winding motor; a sensor including an RFID tag positioned proximate a hazard and a reader positioned on the shuttle car, the reader detecting the RFID tag to determine the presence of the hazard; and a controller configured to receive a signal indicating the presence of the hazard, the controller reducing a speed of the drive motor and a speed of the winding motor in response to the detection of the RFID tag by the reader. - View Dependent Claims (17, 18, 19, 20, 21)
