Dingtai manufactures Komatsu bulldozer track shoes, ground-contact undercarriage components that support machine weight and deliver traction in demanding terrain.
We operate as a factory-direct supplier, providing full OEM manufacturing services, custom dimensions, and consistent quality for global equipment distributors and end users.
Precision-forged shoes resist bending, cracking, and premature wear, reducing unplanned downtime and extending total undercarriage service life in harsh conditions.
With over 20 years of heavy machinery experience, Dingtai maintains ISO9001 and SGS certified processes to ensure repeatable, reliable product quality.
We use 35MnB steel, deep quenching, and controlled heat treatment to create a hardened wear surface with a tough ductile core.
Core Selling Points
- Premium 35MnB Material: High-strength boron steel provides excellent impact resistance and wear performance under extreme bulldozer loads, prolonging track shoe service life.
- Deep Quenching/Heat Treatment: Induction hardening creates a deep, uniform hardened case while preserving a tough core, reducing cracking and abrasive wear.
- Precision Forging/Casting: Advanced forging and CNC machining ensure tight dimensional accuracy, consistent bolt hole alignment, and reliable fitment on Komatsu track chains.
- ISO9001/SGS Certified: Every batch follows ISO9001 quality systems and SGS inspection standards, guaranteeing material traceability and dimensional compliance.

Technical Features
The track shoe body uses 35MnB boron steel, selected for high tensile strength and hardenability. Deep induction quenching creates a wear-resistant surface while retaining impact toughness.
Triple-grouser profiles provide balanced traction and flotation; precision bolt holes and hardened bosses ensure secure mating with track chains under high tension.
Controlled tempering after quenching relieves internal stress and reduces brittle fracture in rock loading and high-impact dozing applications.
Applications
- Mining: dozing overburden, ripping blasted rock, and maintaining haul roads under abrasive conditions.
- Road Construction: earthmoving, grading, and site preparation on hard-packed soil and gravel.
- Quarrying: moving aggregate, heavy rock handling, and steep bench work.
- Landfill and Demolition: tough debris surfaces requiring high-impact wear resistance.
Frequently Asked Questions
Q: What is the minimum order quantity?
A: We offer flexible MOQ, typically 20 pieces per specification, depending on stock and customization requirements.
Q: What is your delivery time?
A: Standard sizes ship in 15-25 days; custom forged orders generally take 30-45 days after drawing approval.
Q: How deep is the heat treatment hardening?
A: Surface hardening depth is typically 5-8 mm, reaching HRC 48-55 for extended wear life.
Q: Do you provide warranty?
A: Yes, a 12-month warranty covers manufacturing defects under normal operating conditions, not normal wear or impact abuse.
Q: Can you match OEM part numbers?
A: Yes, provide Komatsu part numbers or shoe dimensions, and we confirm exact cross-reference and fitment.
Q: Are your track shoes compatible with aftermarket track chains?
A: Yes, our bolt patterns and pitch align with standard Komatsu and major aftermarket track chain systems.
Q: What certifications do you hold?
A: Dingtai is ISO9001 certified; materials and products can be inspected under SGS or equivalent third-party protocols.
Q: Do you offer sample orders?
A: Yes, sample orders are available for existing stock sizes or can be produced with agreed tooling costs.
Maintenance Guide
- Inspect shoes weekly for uneven wear, cracks, or damaged grousers; replace damaged components before they affect track chain alignment.
- Torque track shoe bolts to Komatsu specifications every 250 hours; loose bolts cause bolt hole elongation and shoe loss.
- Monitor track tension daily; excessive tension accelerates shoe and link wear, while loose tension risks detracking.
- Avoid high-speed turns on concrete or hard rock; this scrubs grousers and shortens shoe life.
- Replace shoes when grouser height falls below 25% of original; worn shoes reduce traction and overload other undercarriage parts.
