A tire changer apparatus for mounting and/or dismounting of a tire from a rim of a wheel of a vehicle, said tire changer apparatus comprising:
- a base,
- a wheel-holder engaged with the base and configured to put in rotation, around a rotation axis, a wheel of a vehicle,
- a frame comprising a first and a second column emerging from the base along a direction parallel to the rotation axis,
- a first device comprising:
- an arm carried by the first column, wherein said arm of the first device extends between a front portion directed towards the rotation axis and an opposite rear portion, wherein said arm of the first device is configured to move at least said front portion relative to the wheel-holder to vary a distance between said front portion of the arm of the first device and the rotation axis, and
- a tool terminally carried by said arm at the front portion and configured to operate on at least one of a rim and a tire of a wheel carried by the wheel-holder,
- a second device comprising:
- an arm carried by the second column, wherein said arm of the second device extends between a front portion directed towards the rotation axis and an opposite rear portion, wherein said arm of the second device is configured to move at least said front portion relative to the wheel-holder to vary a distance between said front portion of the arm of the second device and the rotation axis, and
- a tool terminally carried by said arm of the second device at the front portion and configured to operate on at least one of a rim and a tire of a wheel carried by the wheel-holder,
- a first bar placed at the first column and configured to rotate around an axis parallel to the rotation axis, said first bar being connected at least with the front portion of the arm of the first device,
- a second bar placed at the second column and configured to rotate around a respective axis parallel to the rotation axis, said second bar being connected at least to the front portion of the arm of the second device,
- a transmission which connects the first and the second bar to synchronize movement of the front portion of the first and second devices,
- a translation actuator active on one of the first and second devices for movement of the arm of said one of the first and second devices, and
- a servocontrol manually manipulable to activate the translation actuator.
