A system for managing an underground mining machine is disclosed. The system may include a reel-in switch located in an operator station configured to generate plurality of reel-in signals, and a reel-out switch located in the operator station configured to generate a reel-out signal. The system may additionally include an electronic controller in electrical communication with the reel-in switch and the reel-out switch. The electronic controller may be configured to receive the plurality of reel-in signals from the reel-in switch and enter into two or more reeling-in modes in response to the plurality of reel-in signals.

A cable handling apparatus may include a frame and a first cable jaw mounted to the frame. A second cable jaw is pivotally mounted to the first cable jaw so that the first and second cable jaws may be pivoted with respect to one another between an opened position and a closed position. A lock assembly operatively associated with the first and second cable jaws locks said first and second cable jaws in the closed position.

A mobile charging station for charging a vehicle in an underground mine is provided. The mobile charging station includes an electric input configured to receive an input voltage from an electrical network of a mine, at least one output configured to charge a battery of the vehicle connected to the output, a charging circuitry configured to provide electric power to the at least one output, and a voltage transformer arranged between the electric input and the charging circuitry, the voltage transformer being configured to transform the input voltage received via the electric input to a configured output voltage for the charging circuitry.
