Frequently Asked Questions (FAQ) – Bulldozer Track Groups

Q1: How do you ensure the quality and durability of your D155 track groups?

A: Quality is our core advantage. We use high-grade 35MnB alloy steel. Our production process includes:

• Precision Forging: Ensures a dense internal metal structure.

• Deep Induction Hardening: We achieve a surface hardness of HRC 52-58 with a hardening depth of 8mm–12mm (depending on the model). This ensures the core remains tough while the surface is extremely wear-resistant.

• Strict Testing: Every batch undergoes ultrasonic flaw detectionand hardness testing before shipment.

Q2: Are your track groups 100% compatible with original Komatsu or CAT machines?

A: Absolutely. Our track groups are manufactured strictly according to OEM technical drawings and specifications. Whether it’s for a Komatsu D155 or a CAT D8R/D10, we guarantee 100% fitment. We use precision CNC machining to ensure that bolt holes and pitch dimensions are identical to the original parts for seamless installation.

Q3: Can you customize the track shoe type for specific working conditions?

A: Yes. We offer various track shoe configurations to fit your specific needs:

• Single Grouser: For standard heavy pushing.

• Extreme Service Shoes: Thicker shoes for high-impact rock environment

Q4: What is your lead time and shipping capability for bulk orders?

A: * Stock Items: For popular models like D155 or D8R, we usually maintain ready-to-ship stock (within 7 days).

• Custom/Bulk Orders: Production typically takes 20–35 days.

• Logistics: We are experienced in international shipping (FOB, CIF, DAP). Our track groups are packed in heavy-duty sea-worthy pallets with rust-preventative wrapping to ensure they arrive in perfect condition.

Q5: Why should I choose you over a cheaper aftermarket supplier?

A: In the bulldozer business, "cheap" often becomes "expensive" due to downtime.

1. Direct Manufacturer: You get factory pricing without middleman markups.

2. Material Integrity: Many cheap suppliers use recycled steel; we use 100% new, certified alloy steel.

3. Traceability: Every track group has a production batch code for quality tracking. We sell reliability, not just steel.
