Dingtai manufactures Liebherr bulldozer track shoe assemblies, the undercarriage components that support machine weight and deliver traction in demanding terrain.
We offer factory-direct supply with complete OEM manufacturing services for global distributors, dealers, and aftermarket customers requiring precise Liebherr replacement parts.
Our assemblies resist premature wear, cracking, and bolt-hole elongation, reducing unplanned downtime and extending undercarriage service intervals on high-hour Liebherr dozers.
With over 20 years engineering experience, we operate ISO9001 quality systems and provide SGS material reports for every batch.
Each shoe uses 35MnB steel with deep induction hardening and tempered core structures for high tensile strength and extended field life.
Core Selling Points
- Global Brand Compatibility: Dingtai track shoe assemblies match Liebherr OEM pitch, bolt pattern, and shoe width specifications across PR series crawler dozers.
- Premium 35MnB Material: We use 35MnB high-strength alloy steel, offering superior bending fatigue resistance and load-bearing capacity compared to standard carbon steel.
- Deep Quenching/Heat Treatment: Tread surfaces receive deep induction hardening to HRC 52–58, producing a wear-resistant case while retaining a tough, impact-resistant core.
- 100% QC Inspection: Every batch undergoes magnetic particle testing, dimensional inspection, and hardness verification to ensure zero-defect delivery for heavy equipment applications.
Our catalog of Liebherr Bulldozer Track Shoe Assembly includes various specifications, fully compatible with Liebherr PR series bulldozers and crawler dozers.

Delivery & Logistics
Factory-direct pricing and reliable ocean freight with flexible MOQ starting from trial orders. Standard export packaging protects track shoes in transit.
Technical Features
Track shoe assemblies convert hydraulic drive force into ground traction through precision-punched bolt holes and uniform pitch alignment with the track chain.
Deep induction hardening creates a hard tread case while maintaining a ductile core, preventing surface spalling and reducing stress-related failures.
High-strength 35MnB steel improves resistance to bending and cracking under rock impact, extending undercarriage life in abrasive mining and quarrying environments.
Applications
- Mining operations
- Road construction
- Quarrying and aggregate
- Demolition and site preparation
- Landfill and waste handling
- Forestry and land clearing
Frequently Asked Questions
What is the minimum order quantity for Liebherr bulldozer track shoe assemblies?
MOQ is typically 10–20 pieces per specification, but trial samples are available upon request.
What is the delivery time?
Standard production takes 25–35 days after deposit; stock items ship within 7–10 days depending on specification.
How deep is the heat treatment hardening?
Surface hardness reaches HRC 52–58 with effective hardening depth of 8–15 mm depending on shoe size and grouser profile.
What warranty do you provide?
12 months or 2,000 working hours against material and manufacturing defects under normal operating conditions.
Can you match Liebherr OEM part numbers?
Yes. Provide OEM part number or track shoe drawing, and we verify pitch, bolt pattern, and grouser height before production.
Do you offer customized track shoe assemblies?
Yes, custom dimensions, grouser height, hardening patterns, and branding are available using your drawings or reverse-engineered samples.
What materials do you use?
35MnB or 23MnB alloy steel depending on machine weight and application; all materials come with traceable mill certificates.
Maintenance Guide
- Inspect track shoe bolt torque every 250 operating hours. Loose bolts cause pitch misalignment and accelerated wear on chain and sprocket.
- Measure grouser height regularly. Replace shoes when worn below 25% of original height to prevent slippage and drivetrain overload.
- Clean undercarriage after operation in abrasive materials. Packed debris increases rolling resistance and accelerates bushing, link, and shoe wear.
- Check for bent or cracked shoes before each shift. Damaged shoes transfer impact loads to adjacent components and cause uneven track tension.
- Replace track shoe assemblies in sets or matched pairs. Mixing worn and new shoes creates uneven ground contact and reduces traction.
