Advantages of the Excavator Track Shoe Assembly
Enhanced with factory-applied anti-rust coatings and advanced sealed lubrication, these assemblies offer superior resistance to moisture and corrosion. The high-grouser track shoes—available in extended width configurations—significantly reduce ground pressure while maximizing traction and stability to prevent tipping.
Engineered from premium high-manganese steel and high Ni-Mo alloy cast steel, our Excavator Track Shoe Assemblies undergo rigorous quenching and tempering processes. With a surface hardness exceeding HRC 50, they are built to withstand severe mining environments, delivering a service life 2 to 3 times longer than standard components.
This ensures reliable operation across diverse terrains, from mountainous regions to swamps. The optimized pitch design guarantees smooth, efficient performance and is precision-manufactured for seamless compatibility with major models, including the CAT 320 and Sany 55-215 series.
Supplied as complete replacement assemblies, they allow for rapid installation in 10 to 30 minutes with no additional adjustments required, making them ideal for applications ranging from urban construction and residential projects to heavy-duty mining operations.
What is an Excavator Track Shoe Assembly?
The Excavator Track Shoe Assembly (often referred to as the track group) is the primary load-bearing and propulsion unit of the excavator undercarriage mobility system.
Composed of precision-engineered components—including track shoes, track pins, track links, track bolts, and seals—it forms a continuous, interlocking chain structure. This assembly wraps around the sprocket, idler, and track rollers, acting as the critical interface between the machine and the terrain to determine travel stability and operational versatility.
Primary Functions
The assembly functions are engineered around five core operational dimensions:
- Load Distribution: It evenly disperses the gross weight of the excavator, minimizing ground pressure to provide necessary flotation and prevent sinking on soft or muddy substrates.
- Power Transmission: By engaging the track links with the sprocket, the system effectively transfers torque to drive the machine, enabling precise forward, reverse, and steering maneuvers.
- Traction & Stability: Grousers integrated into the track shoe surface are designed to penetrate complex terrains, maximizing grip to prevent slippage or tipping.
- Component Protection: The assembly increases the ground contact area, which mitigates wear on internal undercarriage components.
- Operational Adaptability: Through customized metallurgy and structural designs—such as reinforced wear plates, extended widths for wetlands, or anti-corrosion treatments—the assembly is built to withstand high-impact mining applications and corrosive environments, ensuring maximum machine durability.

| Pitch | Application Scenarios |
|---|---|
| 101, 101T, 125mm | 101mm: Suitable for 2-3 ton small excavators (e.g., Komatsu PC7E, Kubota K020). commonly used for orchard trenching, small courtyard renovations, and other fine operations. 101T: Mostly compatible with small bulldozers, meeting high traction requirements in small engineering projects. 125mm: Suitable for small tonnage equipment, ideal for light-duty operations such as rural road repairs. |
| 135, 140, 154, 156mm | 135mm: Suitable for 4-6 ton excavators (e.g., Komatsu PC40, Hitachi EX40), used for municipal small foundation pit excavation and residential pipeline laying. 140, 156mm: Suitable for medium-sized excavators around 6 tons (e.g., Komatsu PC60, Kobelco SK60), balancing urban road construction and general earthworks. 154mm: Track assembly length covers 280-800mm; suitable for medium-sized equipment, ideal for suburban infrastructure earthmoving. |
| 171, 203, 216, 228.6mm | Mostly suitable for bulldozers and large tonnage excavators. The 228.6mm spec aligns with sealed bulldozer track standards. Commonly used in heavy-duty conditions such as mining stripping and earthmoving for large water conservancy projects; capable of withstanding high tension and impact loads. |
2. Special Condition Applications
| Special Condition Type | Application Scenarios |
|---|---|
| Mining Reinforced Type | Made of high manganese steel with double grouser or reinforced rib structure (e.g., XCMG large tonnage mining track shoes). Surface hardened to resist intense friction and impact from mining rocks. Suitable for high-wear conditions like rock breaking and ore transportation. |
| Rubber Composite / Noise Reduction Type | Rubber-metal composite structure capable of reducing noise by approximately 40 decibels. Suitable for municipal projects and construction in residential areas (e.g., urban road maintenance, underground pipeline laying) to minimize noise impact on the surroundings. |
| Extreme Cold / Anti-freeze Type | Added nickel-based alloy anti-freeze layer, suitable for high-altitude/cold zones down to -45°C (e.g., matching SANY SY16C micro-dozers). Used for frozen soil excavation in the Northeast or snow clearing on plateaus. Prevents low-temperature brittle fracture of the track shoe. |
| Anti-corrosion Type | Features anti-rust coating or special alloy materials. Suitable for port material handling scenarios. Resists salt spray corrosion, ensuring stable operation of bulldozers in humid, salty port environments. |
3. Track Shoe Width Specifications
| Track Shoe Width | Application Scenarios |
|---|---|
| 400 - 600mm (Standard Width) | Standard specifications for excavators and bulldozers. Suitable for general earthworks such as urban building foundation excavation and farmland leveling. Also matches 400-600mm specs for Liugong graders, balancing flexibility with ground bearing capacity. |
| 700 - 900mm (Extended Width) | Mainly suitable for bulldozers, such as certain Shantui SD series models. The high grouser design enhances traction. Suitable for mining auxiliary pushing and hard ground leveling operations. Some excavators with drill rigs also select this for greater horizontal thrust/stability. |
4. Structural Shape & Design
| Structure Shape | Application Scenarios |
|---|---|
| Single Grouser | Mainly suitable for bulldozers, such as certain Shantui SD series models. The high grouser design significantly enhances traction. Suitable for mining auxiliary pushing and hard ground leveling operations. Some excavators with drill rigs also select this for greater horizontal thrust. |
| Double / Triple Grouser | Double Grouser: Mostly for large tonnage mining excavators (e.g., XCMG mining track shoes). Improves grip and prevents bolt loosening during turns. Suitable for mining rock pile operations. Triple Grouser: The mainstream style for excavators. Features two mud-cleaning holes. Suitable for muddy sites, farmland renovation, and other conditions prone to mud adhesion. Self-cleaning. (e.g., 125 triple grouser is common for muddy suburban work). |
| Flat Bottom / Wide Type | Width usually exceeds 800mm. Suitable for swamps and farmland. The gentle ground contact design protects surface layers and reduces turning resistance. Ideal for pipeline projects crossing wetlands, as well as lawn and garden construction to avoid damaging vegetation. |
