RT10-C Rail Flaw Detection Hand Push Cart Serve Korea Railway

Client Background

Korea Railway operates a national rail network requiring regular inspection for internal rail defects Inspection crews must cover long distances with limited possession windows Manual walking inspections are slow and cannot detect transverse cracks in the rail head The railway uses a variety of rail profiles, including 90 to 145 lb rail types Operations occur in extreme temperatures from -30°C to 80°C

Project Challenge

Detecting transverse cracks in the rail head without visual access is critical to prevent derailments Inspection crews need to cover large track sections within short maintenance windows Existing inspection methods are slow, subjective, and lack data for later review Equipment must be portable enough for remote or hard-to-reach track sections Data must be recorded and stored for expert review after the inspection run

Our Solution

RT10-C hand push trolley with 10-channel ultrasonic detection, including one channel for manual verification Simultaneous A-scan and B-scan display for real-time defect analysis and data recording 9-channel scanning of rail with 2–4 MHz frequency range and 3 mm/pulse encoder-driven repetition rate Lithium battery power (14.4V, 10Ah) providing up to 9 hours of continuous operation Amorphous silicon TFT LCD display (8.4 inch, 800×600) with high brightness for visibility in all conditions Differential GPS (1Hz, <5 meter accuracy) for precise location tagging of suspected defects Data file recording capacity up to 400 miles, with selectable range for different inspection needs Compact frame (330x240x220mm) and total weight of 4 kg including battery for easy transport

Final Result

Korea Railway now conducts faster, more reliable inspections of rail head transverse cracks Inspection crews cover more track per shift due to 5 km/h detection speed and digital data capture All inspection data is stored and can be reviewed later by central analysis teams Manual verification is supported by dedicated test channel and real-time scan display Equipment is used across diverse environments from cold northern lines to hot southern sections

Customer Benefit

Detects transverse cracks in rail head that are invisible to visual inspection One person can carry the entire unit (4 kg) to remote or hard-to-access track locations Digital data recording allows re-checking of results after the crew has left site GPS tagging enables precise location of suspected defects for follow-up action Long battery life (up to 9 hours) supports full shift operation without recharging
