<p>A tyre-removal machine comprises a frame (1) with a self-centering unit (4) for locking the wheels in a horizontal position in front of an overlying tool head (13) for mounting/removing the respective tyres, the self-centering unit being connected to the frame (1) by way of a vertically lying articulated parallelogram having one side (55-66) formed by said frame, to the side (5-6) opposite the preceding there being hinged said self-centering unit in such a manner that this latter is able to occupy a lowered wheel loading/unloading position in which it is close to the floor and inclined to the side opposite the frame, and a raised working position, selectable at will, in which it arranges the wheel horizontal and within the radius of action of said tool head. <IMAGE></p> |
