Top Description
We manufacture complete Daewoo track groups, including chains, shoes, bolts, and pins, engineered for excavator undercarriage traction and stability.
Factory-direct production provides comprehensive OEM manufacturing services, ensuring consistent quality and cost control for global equipment distributors and fleet owners.
Premium materials and precise heat treatment prevent premature elongation, bushing wear, and link breakage, reducing unplanned downtime in demanding earthmoving applications.
With over 20 years of heavy machinery manufacturing experience, Dingtai holds ISO9001 and SGS certifications, guaranteeing measurable quality and traceability.
Our track groups use 35MnB steel and deep hardening processes to deliver exceptional core strength and wear resistance under high-impact loads.
Core Selling Points
- Premium 35MnB Material: Forged from high-tensile 35MnB steel, links and pins provide superior resistance to impact fatigue and abrasive wear in tough soil conditions.
- Deep Quenching/Heat Treatment: Induction hardening penetrates deep into bushings and pins, achieving optimal hardness depth to extend track group service intervals.
- Global Brand Compatibility: Produced to match Daewoo and Doosan OEM dimensions, ensuring direct replacement across popular excavator and bulldozer series without modification.
- 100% QC Inspection: Every component undergoes dimensional checks, hardness testing, and magnetic particle inspection before final assembly, eliminating field failures.

Technical Features
Track links are forged from 35MnB steel and induction-hardened to produce a wear-resistant surface while retaining a ductile core for impact absorption.
Bushings are precision ground and deep-hardened to 55–62 HRC, reducing internal pin wear and delaying track pitch elongation under tension.
Bolt holes are machined to OEM torque specifications, preventing shoe loosening and ensuring stable attachment across long operating cycles.
Applications
- Mining
- Road Construction
- Quarrying
- Demolition
- Infrastructure Earthmoving
- Forestry
Frequently Asked Questions
Q: What is the minimum order quantity for Daewoo track groups?
A: Standard MOQ is one 20-foot container or 8–10 sets depending on model; sample orders may be accepted for first cooperation.
Q: What is the typical delivery time?
A: Production takes 25–35 days after deposit or confirmed L/C, depending on order quantity and current production schedule.
Q: How deep is the heat treatment on track bushings and pins?
A: Effective hardening depth is generally 4–8 mm, achieving 55–62 HRC for long wear life.
Q: Do you provide a warranty?
A: Yes, 12 months or 2,000 working hours from shipment, whichever occurs first, covering manufacturing defects.
Q: Can you match my Daewoo part number?
A: Yes, provide OEM part numbers or drawings; our engineering team confirms dimensions before production.
Q: Do you offer complete track groups or individual components?
A: We supply complete track groups with shoes, chains, bolts, and pins, plus individual components as required.
Q: Are your products compatible with Doosan models?
A: Yes, our Daewoo track groups fit many Doosan models, as Doosan acquired Daewoo heavy equipment.
Maintenance Guide
- Installation: Before installation, inspect sprocket and idler wear; install track group with correct tension as specified in the service manual.
- Inspection: Measure track sag weekly; excessive sag accelerates bushing wear and can cause derailment on uneven ground.
- Bolt Check: Check shoe bolts every 250 hours; loose bolts lead to shoe loss and uneven chain loading during operation.
- Replacement: Replace track groups when pin and bushing wear exceeds 20% of original diameter or links show visible cracks.
