Dingtai manufactures heavy-duty Doosan bulldozer track shoe assemblies designed as direct-fit undercarriage components that transfer machine weight and traction to the ground.
Factory-direct manufacturing supports complete OEM services for global distributors, including custom bolt patterns, grouser profiles, and packaging from our China facility.
These shoe assemblies resist bending, cracking, and premature wear, reducing unplanned downtime on demanding dozer applications and lowering undercarriage operating costs.
With over 20 years of undercarriage production and ISO9001/SGS-certified processes, Dingtai supplies traceable quality for fleet maintenance and heavy equipment rebuilds.
Premium 35MnB steel and deep induction quenching deliver a hard wear surface with a tough core, extending service life in abrasive conditions.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB steel provides high tensile strength and impact resistance, preventing shoe plate bending and bolt-hole elongation under heavy dozer loads.
- Deep Quenching/Heat Treatment: Induction hardened to HRC 38–42 with controlled depth, giving a wear-resistant surface while retaining a ductile core for crack resistance.
- Global Brand Compatibility: Engineered for Doosan dozer models and aftermarket undercarriages, with pitch and bolt patterns matched to OEM drawings for direct installation.
- ISO9001/SGS Certified: Manufacturing under ISO9001 quality systems with SGS material reports ensures consistent hardness, dimensions, and full batch traceability.

Technical Features
Each track shoe assembly is precision forged from 35MnB steel, then induction quenched to create a wear-resistant surface over a ductile core.
Bolt hole pitch and link mating faces are CNC machined to OEM tolerances, ensuring correct sprocket engagement and even load distribution across the undercarriage.
Optional single, double, or triple grouser profiles adapt ground pressure and traction for soft soil, rock, or abrasive mining conditions.
Applications
- Open-pit mining and quarry floor dozing
- Road construction and site preparation
- Bulldozer ripping and stockpile spreading
- Landfill compaction and reclamation
- Pipeline right-of-way clearing
- Heavy demolition support
Frequently Asked Questions
What is the minimum order quantity for Doosan track shoe assemblies?
Standard stock orders start at 1–4 pieces; OEM/custom production usually starts at 20–50 assemblies depending on tooling.
What is the typical delivery time?
Stock items ship in 7–15 days; custom production requires 25–45 days after drawing confirmation.
What material and hardness do you use?
Forged 35MnB steel, induction hardened to HRC 38–42 with a hardened depth of 4–8 mm depending on shoe type.
Do you offer warranty?
Yes, 12 months or 2,000 service hours against manufacturing defects under normal working conditions.
Can you match Doosan OEM part numbers?
Yes, provide your existing part number or sample; we cross-reference and produce exact bolt pattern, pitch, and grouser height.
Do you supply complete track group assemblies or individual shoes?
We supply complete shoe assemblies, individual grouser plates, and track chain sub-assemblies based on your downtime requirement.
Maintenance Guide
- Torque track shoe bolts to Doosan specifications after initial 50 operating hours and every 250 hours thereafter.
- Inspect grouser height; replace shoes when wear exceeds 25% or when traction loss becomes noticeable.
- Check link pitch and bushing seal condition; excessive chain stretch indicates replacement of the complete shoe assembly group.
- Clean mating surfaces before installation and tighten bolts in a crossing pattern to ensure even clamp load.
- Never weld on shoes without manufacturer approval; heat can alter heat treatment and cause cracking.
