Our heavy-duty track chains, available in pitch 90–592 mm, undergo exclusive heat treatment that ensures consistent surface hardness, deep hardening, and strong core strength—effectively extending chain life in high-impact, abrasive conditions. For track shoes, certified alloy steels are hardened and stress-relieved, achieving a surface hardness of HRC 42–49, delivering outstanding resistance to bending, breakage, and wear.
These engineering advantages are reinforced by automated production. 3D-vision-guided positioning, automatic pre-tightening, and four-axis intelligent final tightening reduce labor cost by over 75% while eliminating loose or insufficient bolt torque. Our unmanned track-roller assembly line increases efficiency by 25% and more than doubles floating-seal flatness—ensuring long-term reliability.
Field results confirm the value. At the HSQ Open-Pit Coal Mine in Xinjiang, our undercarriage system on a 200-ton excavator has exceeded 10,000 hours without failure. Across a fleet of more than 300 units, another 120-ton excavator recorded 19,324 hours of operation with zero reported undercarriage failures. These real-world results demonstrate the durability and stability built into every Origin Machinery track shoe and chain.
High-quality undercarriage parts are essential to preventing premature wear on crawler equipment. With most maintenance costs coming from the undercarriage, choosing durable, reliable components matters. At Origin Machinery, we engineer undercarriage solutions designed to extend service life, improve efficiency, and reduce your long-term operating costs.
