Dingtai manufactures Doosan track shoes, the ground-contact components that support machine weight and drive traction in undercarriage systems.
We are a factory-direct manufacturer offering comprehensive OEM and replacement track shoe production for global distributors, dealers, and fleet maintenance teams.
Our track shoes resist bending, cracking, and premature wear, reducing unplanned downtime and protecting expensive undercarriage components in abrasive conditions.
With over 20 years of engineering experience and ISO9001/SGS certified production lines, we deliver consistent metallurgical quality and dimensional accuracy batch after batch.
We use 35MnB steel, deep induction hardening, and precision machining to ensure each shoe maintains hardness and strength under extreme impact loads.
Core Selling Points
- Premium 35MnB Material: Track shoes forged from 35MnB steel provide high tensile strength and excellent impact toughness, preventing bending and cracking under heavy loads.
- Deep Quenching/Heat Treatment: Controlled induction hardening achieves 50-55 HRC on wear surfaces while maintaining a ductile core for extended service life.
- 100% QC Inspection: Every batch undergoes hardness testing, dimensional checks, and ultrasonic inspection before shipment, ensuring zero-defect delivery.
- OEM Capabilities: We manufacture to original drawings or provide reverse-engineered replacements that match Doosan part numbers and mounting geometry exactly.
Our catalog of Doosan Track Shoe includes various specifications, fully compatible with Doosan excavators and bulldozers.

Technical Features
Each track shoe is induction hardened to a deep case depth between 8–12 mm, maintaining surface hardness without compromising core impact resistance.
Bolt holes are precision counterbored to seat track bolts flush, preventing loosening and distributing load evenly across the shoe and chain links.
Grouser profile angles are engineered to balance traction and turning performance, reducing side wear and improving stability on soft or uneven terrain.

Maintenance Guide
- Check grouser height, bolt torque, and shoe flatness every 250 operating hours to identify uneven wear or loosening early.
- Re-torque track shoe bolts after the first 50 hours of operation, then every 500 hours to prevent loosening.
- Replace shoes when grouser height wears below 25% of original or link contact surfaces show cracking or bending.
- Always replace shoes in complete sets per side to maintain even pitch and prevent accelerated chain and sprocket wear.
