Product information
Automated Train Wheel Inspection System (WIS)
With more than a million kilometers of railway track around the world, trains are an important method of transporting goods and people. Wheel integrity is essential for safe train operation. For use on different railroad networks, train wheels are manufactured with different diameters, profiles, and weights. To help prevent railway catastrophes, manufacturing quality requirements and standards for railway wheels are increasingly demanding.
Fast and Compliant Inspection
The Wheel Inspection System’s phased array probes inspect the rim, from the tread and one face, in addition to the hub from both sides in less than one minute.
The fully automated system detects the typical defects found in train wheels:
- Rim face volumetric defects
Equivalent to 1 mm–3.2 mm (0.04 in.—0.13 in.) diameter flat-bottom holes (FBHs) with a near-surface resolution of 5 mm–6 mm (0.2 in.—0.24 in.) - Rim tread volumetric defects
Equivalent to 1 mm–3.2 mm (0.04 in.—0.13 in.) diameter flat-bottom holes (FBHs) with a near-surface resolution of 5 mm–6 mm (0.2 in.—0.24 in.) - Hub inner and outer face defects
Equivalent to 2 mm (0.08 in.) diameter flat-bottom holes (FBHs) with a near-surface resolution of 5 mm–6 mm (0.2 in.—0.24 in.)
Optimized Mechanical platform
A complete turnkey inspection station, the WIS is designed to be directly installed in the production line.
Wheels are fed into the system horizontally on a rail, rolling at low speed, fully inspected using phased array ultrasonic probes, and then ejected from the system onto a rail.
Main components of the system:
- Adjustable probe holders out of the water
- Motorized rollers with hydraulic wheel height adjustment out of the water
- Wheel kickers IN/OUT
- HUB inspection water wedge with height adjustment (Optional)
- Automatic Probe Debubbling device
- Fixed immersion tank with water circulation with filtering
Versatile and Efficient System
