LU In-service Automatic Ultrasonic Inspection System for Wheel sets is installed on inspection line of high-speed trains, locomotives and rolling stocks light maintenance workshops. Based on combined utilization of phased array and conventional ultrasonic inspection technology and robotic technology, defects in wheel flange, wheel rim and wheel disk are automatically and efficiently inspected when wheel sets mounted on the train. Under periodic ultrasonic inspection by LU system, wheel sets can be safely used.
LU system can inspect all types of wheel sets. It has been certificated by Ministry of Railway of P. R. China, and widely applied in high-speed train service depots.
Automatic inspecting fatigue defects andvolume defects in wheel flange, wheel rim and wheel disk.
Auto-alarming for defects out of limits.
Automatic lifting & rotating for wheel sets.
Automatic positioning for ultrasonic probes on the wheels.
Real-time monitoring of ultrasonic coupling condition.
