ABSTRACT:
Brake equipment for an underground mining machine, which in use traverses to and fro adjacent to a stationary rail extending along a longwall face and which includes a hydraulic haulage drive motor for hauling the machine along the longwall face, is activated to engage the stationary rail if other than a normal haulage condition of the drive motor is sensed, a control for the drive motor being moved into a neutral, machine non-traversing mode when the brake is applied.
