PATENTED SOLUTION SAVES YOU MONEY

Cat® HDXL with DuraLink™

Innovation drives 20 to 40% longer life

Designed for maximum durability, this patented system consists of Cat® heavy duty extended life (HDXL) with DuraLink, larger diameter bushing, track roller, and sprocket segments. This combination creates a link assembly with more wear material and improved life. It handles your most demanding terrain without breaking. Enhancements include:

D6-D7
  • Improved link to help eliminate cracking and spalling
  • PPR2 provides better pin retention for longer life sealability
  • Larger bolt improves shoe retention in severe applications
D8-D11
  • New crowned link helps to eliminate link scalloping
  • Increased bushing material for extended wear life
  • Improved sealing system eliminates dry joint issues

 

 

Move more material, more efficiently

When the iron is designed specifically for your application, your work is more effective and efficient. We design and manufacture our own undercarriage to ensure full integration with your machines, and we keep developing new products that keep your uptime up and your O&O costs down.
