Dingtai manufactures high-strength Liebherr-compatible track guards that protect undercarriage rollers, idlers, and final drives from rock impact and debris ingress.
We operate a factory-direct manufacturing line, offering comprehensive OEM replacement services for distributors, rental fleets, and construction groups worldwide.
Our track guards prevent premature undercarriage wear and unplanned downtime by absorbing high-impact strikes before they reach critical rotating components.
With over 20 years of engineering experience and ISO9001/SGS-certified production, Dingtai delivers repeatable quality for demanding job site conditions.
Premium 35MnB alloy steel and deep quenching technology create a wear-resistant surface layer, extending service life under continuous heavy loading.
Core Selling Points
- Premium 35MnB Material: High-strength alloy steel provides superior impact resistance and bending fatigue performance, reducing crack propagation in harsh undercarriage environments.
- Deep Quenching/Heat Treatment: Induction-hardened wear surfaces reach 38–45 HRC while retaining a ductile core, balancing hardness with structural toughness.
- Global Brand Compatibility: Precisely engineered mounting patterns fit Liebherr excavator and dozer models, ensuring direct replacement without field modification.
- 100% QC Inspection: Each track guard undergoes dimensional checks, weld inspection, and hardness testing before shipment to guarantee OEM-level consistency.
Our catalog of Liebherr Track Guard includes various specifications, fully compatible with Liebherr excavators and bulldozers.

Technical Features
Hardened wear plates absorb high-impact rock strikes and prevent cracks from spreading into the roller frame or final drive housing.
Precision-cut mounting holes align with OEM bolt patterns, reducing installation stress and maintaining structural integrity under constant vibration.
Deep quenching creates a hard martensitic wear layer over a ductile core, giving the guard both abrasion resistance and fracture toughness.
Applications
- Mining
- Quarrying
- Road Construction
- Demolition
- Heavy Civil Works
- Forestry
Frequently Asked Questions
1. What is the minimum order quantity for Liebherr track guards?
MOQ is one piece for sample or trial orders. Volume pricing applies from ten pieces per model.
2. What is the delivery time?
Standard production takes 15–25 days after drawing confirmation. Stock items can ship within 7 days.
3. How deep is the heat treatment?
Wear surfaces are quenched to 8–15 mm depth depending on plate thickness, achieving 38–45 HRC.
4. What warranty policy applies?
Twelve months from shipment against material and manufacturing defects under normal operating conditions.
5. Can you match original part numbers?
Yes. Provide the Liebherr part number or drawing, and we cross-reference dimensions before production.
6. Can you customize track guards for modified undercarriages?
Yes, we manufacture from sample or CAD drawing with custom dimensions, hole patterns, and reinforcement ribs.
7. What material is used?
35MnB high-strength alloy steel with deep quenching for wear and impact resistance.
8. Do you offer neutral or private labeling?
Yes, neutral packing and custom branding are available for distributors and OEM replacement programs.
Maintenance Guide
- Inspect bolt torque every 250 operating hours to prevent loosening caused by constant vibration and impact shock loading.
- Check weld seams and mounting holes for cracks after high-impact demolition, mining, or quarry work.
- Replace track guards when wear exceeds 30 percent of original plate thickness to maintain protection.
- Use OEM-equivalent fasteners and follow specified torque values during installation to avoid stress concentrations.
