LAC Automatic Ultrasonic Inspection Systemfor Disassembled Wheel Sets is installed on wheel sets maintenance line in high-speed train maintenance centers, rolling stocks and locomotive maitenance depots, and wheel sets manufactories. A combination of phased array and conventional ultrasonic inspection technology are employed to achieve an intensive and precise inspection for defects in wheels and axles. Under periodic ultrasonic inspection by LAC system, the quality of wheel sets is ensured during the train operating.
LAC system has passed appraisal of Railways Bureau of P. R. China, and has been widely applied in rolling stocks and locomotives of depots.
