Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track guard (chain guard) on the Hitachi EX312 is engineered to guide the track chain along its proper path, especially under high-load or uneven ground conditions. It prevents the track from misaligning or "walking out" during excavation, lifting, or climbing, thereby reducing stress on the idler and rollers.
A robust guard also deflects stones, mud, and debris from accumulating around the undercarriage—prolonging the lifespan of essential components and reducing maintenance costs.

This track guard is fully compatible with:
- Hitachi EX312 excavator
- Other Hitachi EX300-series models with similar undercarriage dimensions
Common OEM Reference Numbers (to be confirmed per machine spec):

Premium Material & Durable Construction
Our EX312 track guards are manufactured from Q355 high-strength structural steel, selected for its toughness, impact resistance, and machinability.
Key manufacturing highlights include:
- CNC-Machined Bolt Holes – Ensure exact fitment and easy installation
- Reinforced Side Flanges – Minimize bending or deformation under lateral force
- Anti-Corrosion Finish – Available in black paint, industrial primer, or custom coatings
- Welded Structural Ribs – Add rigidity for heavy-duty operation
- Flat-Milled Bottom Surface – Maintains consistent contact with mounting bracket
Each unit is thoroughly inspected for straightness, hole alignment, and weld integrity before packing.
