Track construction features

  • 100% Virgin Rubber

    Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

  • Continuous Steel Cords

    Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

  • Drop-Forged Links

    Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

  • Corrosion Resistant

    The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

  • Reinforced Sidewalls

    Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

  • Low-Vibration Tread

    Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
