Wheel sets are critical components in train safety and performance. Even minor defects in wheel geometry, such as flat spots, ovalization, or wear, can lead to operational instability, noise, and accelerated rail degradation. Detecting these issues during inspections requires highly precise and reliable equipment to ensure the safety and longevity of both the wheel sets and the railway infrastructure. Traditional inspection methods often lack the precision and speed necessary for modern railway maintenance needs, making advanced technology a necessity.
