Dingtai manufactures forged track shoes for Doosan bulldozers, serving as the ground-engaging component of the undercarriage system. Each shoe bolts directly to the track chain, supporting machine weight and transmitting drive force through demanding terrain.
We operate a factory-direct manufacturing facility offering comprehensive OEM services. Global distributors and fleet owners receive direct pricing without intermediary markups, backed by full technical documentation and consistent batch-to-batch dimensional accuracy.
Our track shoes are engineered to resist cracking, bending, and premature wear under extreme load. By eliminating premature shoe failure, we help procurement teams reduce unplanned downtime, lower replacement frequency, and protect track chain integrity across the entire undercarriage lifecycle.
With over 20 years of specialized manufacturing experience, Dingtai maintains ISO9001:2015 certification with SGS-verified material traceability. Every production lot undergoes documented quality control, ensuring your Doosan fleet receives components that meet or exceed OEM service specifications.
Each track shoe is forged from 35MnB alloy steel and undergoes deep induction quenching, achieving surface hardness of HRC 48-55. This heat treatment creates a wear-resistant tread surface while maintaining a ductile core that absorbs impact and resists fracture.
Core Advantages
- Premium 35MnB Material: We forge track shoes from 35MnB alloy steel, delivering superior tensile strength and impact resistance compared to standard carbon steel alternatives used by budget suppliers.
- Deep Quenching/Heat Treatment: Induction hardening penetrates 8-12mm deep on tread surfaces, producing HRC 48-55 hardness that withstands abrasive rock, gravel, and high-friction operating conditions.
- Precision Forging/Casting: Computer-controlled forging dies guarantee bolt-hole alignment within ±0.2mm tolerance, ensuring seamless installation on Doosan track chains without modification or reaming.
- 100% QC Inspection: Every track shoe undergoes dimensional verification, hardness testing, and visual inspection before dispatch. Magnetic particle testing detects subsurface defects prior to shipment.
Product Range
Our catalog of Doosan Bulldozer Track Shoes includes various specifications, fully compatible with Doosan excavators and bulldozers.

Technical Features
Forged track shoes utilize grain-flow alignment along the load path, eliminating porosity found in cast alternatives. This metallurgical structure delivers superior fatigue resistance under the cyclic bending forces generated during bulldozer turning maneuvers.
The induction hardening process creates a martensitic wear surface while preserving a tough, ductile core. This dual-hardness profile prevents the catastrophic brittle fracture that occurs when fully hardened shoes strike rock ledges or debris.
Precision-machined bolt holes ensure uniform clamping force distribution across the shoe-to-chain interface. Improper hole alignment concentrates stress, causing premature bolt loosening and accelerated wear on both the chain link and shoe mounting surface.
Applications
- Mining: Surface coal and mineral extraction with continuous abrasive contact.
- Road Construction: Subgrade preparation, grading, and demolition projects.
- Quarrying: High-impact rock handling and aggregate processing environments.
- Landfill Operations: Compaction and material spreading on high-wear surfaces.
- Forestry: Clearing and earthmoving over stumps, roots, and irregular terrain.
- Heavy Civil Works: Dam construction, pipeline right-of-way preparation, and mass excavation.
Frequently Asked Questions
Q1: What is the minimum order quantity for Doosan track shoes?
We accept orders starting at 10 pieces per specification. For ongoing fleet customers, we offer scheduled release orders with inventory holding.
Q2: How long is delivery?
Standard production lead time is 15-25 days. Ocean freight to US ports typically adds 20-35 days depending on destination and customs clearance.
Q3: What is the heat treatment depth of your track shoes?
Our induction quenching achieves 8-12mm case depth on the tread surface, with a hardness gradient transitioning to the ductile core.
Q4: What is your warranty policy?
We provide a 12-month or 2,000-hour warranty against manufacturing defects. Claims require photographic documentation and operational data.
Q5: Can you match my existing Doosan part numbers?
Yes. Provide your OEM part number, and we will cross-reference to our production database. We manufacture direct-fit replacements for all listed models.
Q6: Are these genuine Doosan parts?
No. These are aftermarket replacement parts manufactured by Dingtai to OEM-compatible specifications. They are not affiliated with or endorsed by Doosan Infracore.
Q7: What materials are used?
All standard track shoes are forged from 35MnB alloy steel. Alternative materials including high-manganese steel are available for extreme-wear applications.
Maintenance Guide
Installation: Torque all track shoe bolts to Doosan specifications using a calibrated torque wrench. Re-torque after the first 50 operating hours to compensate for initial bedding settlement.
Inspection: Check shoe grouser height monthly. Replace when grouser wear exceeds 70% of original height to maintain traction efficiency and prevent slippage under load.
Bolt Monitoring: Loose bolts cause accelerated wear on both shoe and chain link. Inspect bolt torque every 250 hours and replace any bolt showing thread deformation or corrosion pitting.
Replacement Interval: Track shoes typically require replacement after 2,000-3,000 hours in abrasive conditions. Premature wear indicates improper track tension or misaligned idler components.
