The Komatsu PC2000 is a cornerstone equipment in mining projects worldwide. Known for its power and reliability, it operates in some of the harshest environments, from open-pit coal mines to iron ore operations. However, one of the most critical systems on the PC2000 is also the most wear-prone: the undercarriage.
Key Maintenance Recommendations for PC2000 Undercarriage
1. Scheduled Inspections
Routine checks are essential to prevent small issues from becoming costly failures.

2. Track Tension Management
Incorrect tension accelerates wear and causes safety risks.
Recommended sag: 50–60 mm for PC2000
Over-tightening increases wear by up to 40%
Under-tightening can lead to derailments on rocky terrain
Track tension should be checked every 200 operating hours, especially in variable conditions such as wet or loose soil.
