ABSTRACT:
This disclosure is directed to a mine locomotive braking system having an independently operated back-up braking capability, responsive within a matter of several seconds in stopping power and adaptable for retrofit to virtually any existing mining locomotive braking system to form a combination having the aforementioned capabilities in combination with an existing manually operated mechanical braking device usually requiring either physical strength or weight, viz., manually dependent physical force, on the part of the mine locomotive operator to force the arcuate brake shoes in contact with the outer wheel surfaces, thus making it susceptible to extended stopping times. The system is operated by a series of push buttons; the actuation of which operates a hydraulic mechanism whose output portions cause pressure to be applied upon a brake bar by cylinders thereby causing motion of the bar which in turn operates brake shoes which apply direct pressure to the locomotive wheels. A change of direction mechanism is employed to pivotally change direction to handle the rear wheels (or front wheels) as the case may be.
