The Revolution in Tyre Changing Operations
In recent years the requirements in tyre service have become more and more challenging both for equipment and 
operators. Wheels are increasing in diameter, width and weight. More and more UHP and run-flat tyres with their extremely stiff sidewalls become popular. So that tyre shops are in a position to efficiently change tyres, while preserving the material without stressing the operator, Snap-on Equipment developed the Quadriga – a tyre changer which sets new standards at its higher end of the market. Owing to substantially automated processes wheels of up to 30” rim diameter and up to 47” overall diameter can be handled in an incredibly short time. This technology is implemented in the John Bean Quadriga and Hofmann monty quadriga 1.
The wheel lift raises the wheel to the clamping flange where the wheel is clamped. Laser scanners detect the geometric dimensions of the wheel to position clamping flange, bead breaking rollers and mounting head automatically and exactly relative to the wheel. Once the wheel has been clamped hydraulically, the operator will only have to choose one of the five operation programs.
Automatic demounting and mounting of the tyre is started with a joystick. None the less the operator will never loose control of the operation. The intelligent controller ensures that exactly adjusted forces are applied on the tyre during every single step of the operation so that both tyre and rim are protected against damage. The Quadriga excels through its high level of ergonomics, universal use and accurate and controlled automated processes.
