摘要:
The machine has a base, a fixed arm connected to the base and defining an inverted "U"-shaped configuration having a free end. A conventional bead extractor is connected to the free end of the fixed arm, which overlies a rotatable tire-supporting platform driven by a drive unit. The rotatable platform is mounted on a plate having opposite sides provided with bearings movably connected to a pair of parallel guide elements fixed to the sides of the base. A fine-adjustment mechanism is provided for positioning the plate and the rotatable platform with respect to the bead extractor and the fixed arm for accommodating a wide range of different sizes of wheels and tires.

A device for fitting and removing tires includes a support having a connecting portion associable with the movable arm of a tire changing machine, a first protruding element associated with the support and suitable to be positioned in correspondence with a section of the edge of a wheel rim, a guide element having a substantially elongated shape and extending substantially orthogonal to the protruding element, a gripping tool associated with the support, suitable to be inserted between the tire and the rim and having a substantially curved end section, the gripping tool being movable between a retracted position, wherein the end section is arranged in proximity of the first protruding element, and an extracted position, wherein the gripping tool extends from the first protruding element towards the wheel. The first protruding element is arranged substantially at the side of the gripping tools, in correspondence with a side of the gripping tool substantially opposite to the guide element.

摘要:
A kit of removable adapters for converting conventional kinds of tire changing machine into tire changing machines for special run-flat tires comprising: a first separator element for separating the tire and the wheel rim shaped and fixable by way of complementarily shaped profiles and with corresponding devices to the lower end of the conventional corresponding vertical tool with which the tire changing machine is provided; a second bead breaker element provided with an auxiliary shoe for contacting and pushing the beads of a tire and with coupling elements for removable coupling to the conventional bead breaker shoe with which the tire changing machine is equipped; a lever for the localized extraction of the beads of the tires from the respective flanges of the wheel rims, which can be functionally coupled to supporting elements adapted for resting against the wheel rim in order to protect the wheel rim.
