Track Link Reliability Proven During Typhoon Rescue Operations

During 2024Typhoon Haikui's assault on Fujian, 32 excavators equipped with Yangxin track links operated continuously for 120 hours in floodwaters, clearing 18 landslide sections. Rescue captain Wang Zhigang reported: "Despite sharp debris in torrents, Yangxin track shoes and links sustained zero fractures, with bolt assemblies maintaining 100% fastening integrity."

These links feature Yangxin's patented "Dual-Quenching Technology": initial 870°C bulk quenching ensures core toughness, while secondary laser quenching achieves HRC55 hardness on rail surfaces. Combined with anti-corrosion track bolts, preload force persists even in silt immersion. Post-mission inspection revealed only 0.12mm pin wear (industry average: 0.3mm).

GM Chen Yang disclosed: "We're developing smart track links with embedded RFID chips to monitor bolt torque in real-time. When plow bolt preload drops by 15%, the system triggers alerts, boosting preventive maintenance efficiency by 60%."

*Market Response: Yangxin track systems now equip Sany SY950H 50-ton excavators, reducing failure rate to 1.2 incidents/10,000 hours.*
