ABSTRACT:
A mine supply car has fixed, rail-engageable wheels, and adjustable selectively useable road wheels mounted in elongate frames along the sides of the car. The road wheels are mounted on pivot arms for swinging movement between raised inoperative positions and lowered operative positions. The arrangement allows the car to be converted between rail and road use by relatively effortless manual movement of the road wheels.
