Train Wheel Inspection

AAR, ISO, and EN Compliant

Railway transport continues to play an important role in the transportation industry; due in large part to its speed, reliability, and affordability. To maintain this viability, ensuring train safety and integrity is key. Stringent regulations are imposed on the inspection of train wheels and axles in both the manufacturing and service sectors. To meet and exceed these strict criteria, Olympus provides the power and flexibility of its FOCUS LT/TomoView package to experienced and knowledgeable integrators, who are then able to deliver fully code-compliant inspection systems.

Optional High Speed Train Inspection Requirements

Multizone Coverage

Specific code requirements subdivide the rim area into zones requiring additional coverage.

Sub Bore-Hole Area Inspection

Some codes require the inspection of the area under the bore holes, which is achieved with a Pitch-Catch configuration.

High-Performance Package

Experience the power of the FOCUS LT acquisition unit, the flexibility of the TomoView software, and the customization capability provided by the software development kits (SDK). These three components work in unison to maximize the performance of train wheel inspection systems.
