How does the mining electric locomotive locking device work?
There is a safety design called a locking device on the controller of the mining electric locomotive. What is its function? How does it work?
The locking device on the controller is designed to prevent the driver from misoperation during driving. When the reversing handle is not in the "forward" or "reverse" position, the cam contactor will be stuck. It shows that the main control handle (speed handle) cannot be rotated at zero position. Conversely, when the main control handle is not at the zero position, the reversing handle will also be stuck in the "forward" or "reverse" position. In case the driver misuses reverse braking.
