EloWheel – RPT16 Aircraft Wheel Inspection System

Manufactured in the US in cooperation with our branch office Rohmann LP, we offer the EloWheel - RPT 16 aircraft wheel inspection system. Aircraft rims are are exposed to high mechanical loads, especially during take-off and landing. Additionally enormous thermal stresses occur while applying the brakes after touching down. Thus rims of both, civil aircrafts as well as military aircrafts, have to be inspected for any damages according to the regular maintenance intervals. Regions of maximum stresses, e.g. the bead seat radius and the bore holes, are of special interest. Using a modern eddy current testing instrument, the surface as well as the volume of the wheel rims is inspected by both, a high frequency and a low frequency probe simultaneously.
