2. Key Features & Design

(1) Structural Design

• Lug Pattern: Multi-grouser (for superior traction) or flat design (for reduced ground disturbance)
• Bolt Holes: Standard 2-bolt or 3-bolt configuration (machine-dependent)
• Mud/Snow Shedding: Optimized self-cleaning gaps to prevent material buildup

(2) Durability & Performance

• Wear Resistance: Critical zones hardened to HRC 50+ for extended service life
• Tensile Strength: ≥ 850 MPa – withstands high-impact loads in rocky/abrasive conditions
• Fatigue Tested: Validated through CAT’s 10,000+ hour simulated field testing

(3) Compatibility

• Matches CAT E70B Undercarriage System (rollers, idlers, sprockets)
• Pitch: 172 mm (verify for exact machine, e.g., 307E standard)
• Width: 450 mm (typical for 30-40T class excavators)
