Key Features & Design

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

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

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)

Technical Specifications

Parameter	Value
Unit Weight	22.5 kg ±0.5 kg
Bolt Spec	CAT M24×2.0 (Grade 10.9)
Operating Temp.	-40°C to +120°C (extreme conditions require special lubrication)
Load Capacity	≥ 15 MPa (static)
Corrosion Protection	Phosphate coating + anti-rust oil

Recommended Applications & Limitations

Ideal for:

Earthmoving, construction, utility work
Moderate-wear environments (gravel, clay, asphalt)

Not recommended for:

Prolonged exposure to acidic/saline corrosion (requires stainless steel variants)
High-impact mining (use XT-series reinforced shoes)

Installation & Maintenance

Installation Guidelines

Torque bolts to CAT-specified 450-500 N*m + apply thread locker
Inspect track pins & bushings for wear before assembly

Maintenance Protocol

Daily: Clear debris lodged between shoes
Every 500 hrs: Re-torque bolts, lubricate pins
Replacement Threshold: Replace if lug height wears beyond 30% (or <15 mm remaining)
