L&H Undercarriage for Hydraulic Shovels Download Tech Sheet PDF


Engineered for optimal life, L&H Undercarriages for hydraulic shovels, a distributed WearPro® assembly that includes an advanced monitoring system, have been designed to eliminate premature failure of components due to lube and seal issues.


  • Optimized track design. Improved internal structure and materials prevent cracking in the trackpads.
  • Upgraded pins. Increased pin eyes provide more bearing surface and upgraded materials improve strength and longevity.
  • Overpitched drive sprockets. As the shoes wear and stretch apart, overpitch drive sprockets allow for continuous take-up without skipping a tooth.
  • Longer-lasting rollers. 1-piece forged lower rollers last 30% longer than cast rollers and have no welded seams.
