Engineered for the Toughest Terrains
The D9 series represents the workhorse of global mining and large-scale earthmoving. At GT Industries, we understand that D9 undercarriage components must withstand extreme vertical loads and high-abrasion environments. Our D9 product line is engineered using premium alloy steels and advanced deep-induction hardening to ensure your fleet maintains maximum uptime in the most unforgiving conditions.
Technical Excellence: The GT Advantage
Extreme Service Track Shoes: Our D9 shoes are designed with reinforced grousers for superior bending resistance and extended wear life in rocky or abrasive soil.
Sealed and Lubricated Track (SALT) Technology: Our D9 link assemblies feature advanced seal groups to retain internal lubrication, significantly reducing pin and bushing friction and internal wear.
Structural Integrity: Forged from high-grade boron steel, our components exhibit superior grain structure, providing the fracture toughness required for heavy ripping and dozing operations.
Reliable Retention: High-tensile hardware specifically rated for D9 torque specifications ensures component security under maximum drawbar pull.
