An apparatus for mounting and demounting a tyre relative to a corresponding wheel rim, wherein the apparatus comprises:
- a wheel-holder unit, configured to receive and lock the wheel at an operating position and to set it in rotation about an axis of rotation;
- a plurality of tools, configured to interact with the tyre to mount and/or demount the tyre;
- a hydraulic circuit comprising a pump;
- a plurality of hydraulic actuators, connected to the hydraulic circuit, wherein each actuator of the plurality of actuators defines an internal space and includes a piston which is slidable inside the internal space, wherein the piston divides the internal space into an opening chamber and a closing chamber,
- wherein the hydraulic circuit is configured to drive the actuators of the plurality of actuators synchronously.
A method for demounting a tyre from a respective wheel rim, comprising the following steps:
- receiving and locking the wheel to a wheel-holder unit;
- rotating the wheel about an axis of rotation by means of the wheel-holder unit;
- moving a plurality of tools, wherein one or more tools, of the plurality interact with the tyre to demount the tyre;
- synchronously driving a plurality of hydraulic actuators by means of a hydraulic circuit comprising a pump and connected to the actuators of the plurality of actuators.
