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.
