ABSTRACT:
A tire changing machine of simple and rugged construction particularly for changing the tires of truck wheels and characterized by a construction allowing readily adjustment to different sizes of tires and allowing fast tire changing operation solely by axially pushing the rim out of the tire while simply clamping down the latter on a base. This tire changing machine comprises a base having opposite ends and defining an intermediate cavity, a lifting linkage system in the cavity carrying a wheel rim carrying plate, a hydraulic cylinder actuating the linkage system to lift the wheel rim carrying plate, and tire clamps pivotally connected on the opposite ends respectively of the base and having jaws adjustable to different sizes of rims and clamping down the tire around a rim on the wheel rim carrying plate.
