100% tesion relieved car chassis due to frictionless aerostatic air bearing. Air buffered aerone turning plates for wheel alignment at the highest precision level. Modern vehicles require accurate adjusted chassis. Increasing quality and more powerful engines of vehicles require higher accuracy to chassis adjustments and thus on the wheel alignment technique. The frictionless air buffer of aerone-system provides outstanding vehicle positioning for high-precision wheel alignment. With the central control unit, the plates can be controlled individually or axle wise. For driving on/over, the units can be fixed by vacuum. The aerone can be used as two- or four-plate-system.
