Top Description
Komatsu track guards are protective shields that bolt directly to the undercarriage frame, shielding rollers, idlers, and final drives from rock impact and debris ingress.
We operate a factory-direct manufacturing line with comprehensive OEM services, providing precision-matched guards for Komatsu distributors and fleet owners worldwide.
Rugged guard structures prevent premature undercarriage wear, reduce costly track derailment risks, and eliminate unscheduled downtime in harsh terrain.
Dingtai holds ISO9001 and SGS certifications with over 20 years of specialized engineering machinery manufacturing, ensuring consistent batch quality and full traceability.
Hot-formed 35MnB steel plates, combined with deep-penetration welding and stress-relief processes, deliver superior impact toughness and crack resistance under extreme loads.
Core Selling Points
- 20+ Years Experience – Two decades of focused engineering machinery fabrication means every guard reflects proven design iterations and field-validated reliability.
- Global Brand Compatibility – Guards are precision-engineered to match Komatsu OEM bolt patterns and frame geometries, ensuring direct fitment without modification.
- Premium 35MnB Material – High-tensile 35MnB steel offers exceptional yield strength and impact absorption, outperforming standard carbon steel in abrasive conditions.
- 100% QC Inspection – Every unit passes dimensional checks, weld integrity tests, and surface coating verification prior to release, guaranteeing on-spec delivery.

Delivery & Logistics
We ship from Quanzhou with flexible MOQs, factory-direct pricing, and consolidated freight options. Standard guards are stocked; custom orders typically dispatch within 25–35 days.
Technical Features
Guard geometry incorporates reinforced cross-ribbing that distributes impact force laterally across the frame, preventing concentrated stress points that lead to fracture.
The bolt-on design utilizes high-strength Grade 10.9 fasteners with prevailing torque locking features, maintaining clamp load even under constant vibration and shock.
A multi-stage corrosion defense system with zinc-rich primer and polyurethane topcoat resists moisture, salt, and chemical attack in mining and marine environments.
Applications
- Mining and quarrying
- Heavy road construction
- Demolition and rock handling
- Forestry and land clearing
- Large-scale earthmoving
Frequently Asked Questions
- What is the MOQ for Komatsu track guards?
- Standard stock guards ship from 1 unit. Custom dimension guards typically require an MOQ of 10 pieces.
- How long is delivery time?
- Stock items ship within 7 days. Custom orders require 25–35 days depending on complexity and quantity.
- What is the depth of heat treatment on your guards?
- We achieve 3–5 mm hardened layer depth on wear-prone edges, verified by micro-hardness traverse testing per batch.
- Do you match Komatsu part numbers exactly?
- Yes. Supply your OEM part number or drawing, and we manufacture to mirror original dimensions and mounting interfaces.
- What warranty applies?
- 12 months or 2,000 hours against manufacturing defects, excluding normal wear and misuse.
- Are installation bolts included?
- Yes, all mounting hardware (Grade 10.9 bolts, washers, nuts) is included unless otherwise specified.
- Can you produce guards for older Komatsu models?
- Absolutely. We support legacy models including D155-1, D85-18, and PC300-6 with equal precision.
- What material certificates are provided?
- SGS-certified mill test reports for 35MnB chemistry and mechanical properties accompany each shipment.
Maintenance Guide
- Inspect guards for cracks or deformation every 250 hours; pay close attention to weld toes and bolt holes.
- Verify bolt torque with a calibrated wrench; loose bolts accelerate guard wear and risk detachment.
- Replace any guard exhibiting a crack longer than 25 mm to prevent catastrophic failure under load.
- Check alignment after any track shoe replacement or frame repair to ensure guard-to-roller clearance remains uniform.
