Phoenix Inspection Systems Limited have further developed their ultrasonic NDT solution for the automated inspection of train wheel hollow axle sets, typically used in high speed passenger trains, where lighter weight components have a distinct advantage.

Trains travel at speeds in excess of 200km/h and subject their hollow axles to increased strain risking the structural integrity and reliability. The axle life is a crucial part of both the safety and economic performance of a train and hollow axles need to be inspected periodically, using an ultrasonic testing solution to detect potential internal defects and cracks in the outer surface. Early stages of detection can improve the efficiency in the use of axles by extending their life. However, inspection which takes a train out of service impacts on the economic aspects of a train’s operation.

The Axle Bore Scanner has been developed by Phoenix ISL over the years and the most recent automated design allows fast and efficient inspection of the axle in-situ from the trackside, reducing inspection time and costs.

The system is compact, portable and easy to use by a single operator and can inspect axle bores from Ø25mm to Ø110mm by changing the probe head to the appropriate diameter. Inspecting bores of any length is possible using interchangeable lances to give the required stroke length. With two motorised axes for axial and circumferential motion through the bore, the Axle Bore Scanner can inspect either by helical, helicoidal or raster scan patterns (370° x 2150mm).

Andrew Brewis, Sales Manager at Phoenix ISL said: “The latest version of the Phoenix Train Axle Bore scanner has the addition of seals either side of the probe head to retain couplant, which means a cleaner inspection is achieved; A great benefit when inspecting at the trackside.”
