How to Adjust Track Tension on Rotary Drilling Rig Undercarriages

Proper track tension is crucial for maintaining the stability, performance, and longevity of rotary drilling rig undercarriages. Incorrect track tension can cause equipment wear, reduced traction, and even derailment. This article discusses track tension adjustment techniques, inspection schedules, and troubleshooting tips for rotary drilling rigs.

1. Why Track Tension Adjustment Is Important

Correct track tension ensures:

  • Improved Traction: Prevents track slippage on uneven or muddy terrain.
  • Reduced Equipment Wear: Minimizes stress on rollers, idlers, and drive motors.
  • Increased Equipment Lifespan: Extends the life of the undercarriage system.
  • Enhanced Site Safety: Reduces the risk of accidents due to derailment.

Example: The XCMG Used Rotary Drilling Rig includes a track adjustment system designed to maintain optimal track tension even in demanding drilling environments.

2. How to Adjust Track Tension

  • Inspect Track Tension Regularly: Inspect daily or after working in muddy or rocky conditions.
  • Measuring Track Sag: Use a straight edge and measure track sag according to manufacturer recommendations.
  • Adjusting Track Tension: Loosen the track adjuster valve, add or remove hydraulic grease, and tighten the adjuster valve.

3. Maintenance Tips for Track Tension

  • Inspect Before and After Use: Check for track sag, misalignment, and debris buildup.
  • Clean Tracks Regularly: Remove mud and dirt to prevent wear.
  • Lubricate Moving Parts: Ensure proper lubrication of track rollers, idlers, and sprockets.
  • Follow Manufacturer Specifications: Always refer to equipment manuals for correct track tension settings.

4. Common Track Adjustment Mistakes to Avoid

  • Skipping Inspections: Ignoring daily track inspections can cause sudden failures.
  • Over-Tightening Tracks: Tracks that are too tight cause premature wear and increased fuel consumption.
  • Under-Tightening Tracks: Loose tracks can derail and cause accidents.
  • Improper Cleaning: Use appropriate tools and avoid pressure washing sensitive components.

5. Case Study: Successful Track Tension Adjustment

Location: Mountain Drilling Project

Challenge: Frequent track derailments caused by improper track tension settings.

Solution: The maintenance team introduced a track tension inspection and adjustment schedule for the XCMG Used Rotary Drilling Rig, combining regular inspections, precise adjustments, and proper cleaning. The project’s efficiency improved by 80%, significantly reducing downtime caused by undercarriage failures.

6. Safety and Environmental Compliance

  • Proper Waste Disposal: Follow local regulations for disposing of used hydraulic grease and worn parts.
  • Operator Training: Train operators on track tension adjustment procedures and safety protocols.
  • Maintenance Records: Maintain detailed logs of track inspections, adjustments, and replacements.
