Abstract
A tire changing machine for changing difficult to mount tires is provided. The machine utilizes various implements configured about the machine's chassis in such a way that they do not interfere with each other's operation. In this way, the machine enables an operator to effectively change various tires.
Claims18
A tire changing machine comprising:
- a chassis defining a back, front and first and second lateral sides;
- a rotatable turntable configured to retain a wheel rim;
- a tower carrying a mount/demount head movable toward and away from the wheel rim in a plane angularly offset from a back-to-front axis of said chassis extending transverse to a rotational axis of said turntable;
- a plurality of pedal actuators located on a first lateral side of said chassis, said actuators being operative to control operation of at least said turntable;
- and,
- wherein the tiltable tower tilts toward the turntable from a position generally diagonally across the chassis from said pedal actuators.
