Dingtai manufactures Daewoo track guards, heavy-duty undercarriage components that shield track links, rollers, and final drives from impact damage during operation.
Factory direct services include OEM and ODM manufacturing, allowing global dealers and rental fleets to source durable replacement guards at competitive pricing.
These guards prevent premature undercarriage wear and downtime by blocking rock ingress, reducing derailment risk, and absorbing impact loads in harsh terrain.
With over 20 years of engineering experience and ISO9001/SGS certified production, Dingtai delivers consistent quality for heavy machinery replacement parts.
Premium 35MnB steel and deep quenching heat treatment provide high surface hardness and extended service life under abrasive working conditions.
Core Selling Points
- Global Brand Compatibility: Produced for Daewoo and Doosan excavator series with OEM-equivalent bolt patterns and mounting dimensions for direct replacement.
- Premium 35MnB Material: High-strength alloy steel offers excellent impact resistance and durability compared with standard carbon steel guards.
- Deep Quenching/Heat Treatment: Induction hardening creates a wear-resistant surface layer while maintaining a tough core to resist cracking.
- ISO9001/SGS Certified: Certified processes and 100% dimensional inspection ensure reliable quality control for every production batch.

Technical Features
The guard’s mounting interface is CNC-machined to OEM tolerance, maintaining bolt torque and alignment under continuous vibration and impact.
Deep quenching creates a martensitic surface layer with high hardness while the softer core absorbs shock, reducing fracture risk.
Precision-formed profiles follow track frame geometry, preventing debris accumulation between track links, track rollers, and idler wheels.
Applications

Frequently Asked Questions
What is the minimum order quantity for Daewoo track guards?
Stock size MOQ is 20 pieces. Customized trial orders are accepted based on existing forging or casting molds.
What is the delivery time?
Standard models ship within 7–15 days after deposit. Custom production typically takes 25–35 days.
How deep is the heat treatment layer?
Induction-hardened depth is generally 4–8 mm depending on part thickness, with surface hardness HRC 50–55.
What warranty policy applies?
We provide a 12-month warranty from shipment against material and manufacturing defects under normal operating conditions.
Can you match our part numbers?
Yes. Send your OEM part number or drawing, and we will confirm exact interchange and dimensions before production.
Do you produce track guards for older Daewoo models?
Yes. We cover legacy DH, Solar, and current DX series models, including discontinued part numbers.
Maintenance Guide
- Inspect mounting bolts every 250 operating hours; tighten to OEM torque specifications to prevent loosening.
- Check for cracks, deformation, or deep scoring; replace guards showing structural damage before undercarriage components wear.
- Clean debris buildup around guards regularly to avoid abrasive wear and improper track tension.
- Replace track guards in sets when wear exceeds 30% of original thickness or after major impact damage.
