TYRE CHANGING MACHINE AND METHOD FOR USING A TYRE CHANGING MACHINE

A tyre changing machine (100) comprises: a wheel-holder unit (200); a frame (400); a bead breaker unit (300) including a bead breaking arm (301) articulated to the frame (400) to rotate about a vertical axis (Y), a bead breaker tool (302) and a bead breaker actuator (303) to move the bead breaker tool (302) towards and away from a wheel (R); a lifting device (500), including a lifting arm (501) and a supporting platform (502), defining a horizontal surface on which to rest the wheel (R) and connected to the lifting arm (501) to be movable between a lowered position and a raised position. The lifting device (500) also comprises a lifting actuator to move the supporting platform (502) between the raised position and the lowered position, and a box-shaped body (600) that is operatively coupled to the flank (400b) of the frame (400); the lifting actuator is at least partly positioned in the box-shaped body.
