Abstract: The present invention concerns a wheel-holder including: a support base, a shaft slidingly movable with respect to the support base and having a plurality of stops, a support plate carried by the shaft and configured to receive the rim of a wheel, a block carried by the support base and configured to engage a stop for locking the shaft in an operating position, preventing the relative sliding between support base and shaft. The block includes an insert movable with respect to the shaft, a maneuvering element active on the insert and configurable between a thrust position and a release position. The block includes a pusher which, in the release position of the maneuvering element, thrusts on the insert to maintain it in engagement with the stop.

Abstract: A tire changer apparatus for the assembly or disassembly of tires from a rim of a wheel of a vehicle, said tire changer apparatus comprising: a base; a drive unit movable along a predetermined direction and configured to rotate, around a rotation axis, a wheel of a vehicle; a frame emerging from the base. The rotation axis of the wheel and the predetermined direction define an ideal plane of movement of the drive unit. The apparatus also comprises a first and a second device, each of which comprises: an arm hinged to the frame and configured to rotate around a respective axis parallel to the rotation axis of the wheel, a tool configured to operate on a rim and/or a tire of a wheel; the first and second devices are configured to arrange the respective tools on opposite sides with respect to said ideal plane.
