Undercarriage for Construction Equipment




Every construction site presents unique challenges. Machines with Cat® undercarriage have proven they can take on those challenges — moving more material at a lower cost. Because Caterpillar manufactures its own undercarriage, every component meets strict specifications and quality standards that no competitor can match. Take a closer look at all that Cat undercarriage has to offer.



Construction excavation requires machines to push through some of the most abrasive materials. You need an undercarriage that can take on that challenge with industry-leading low cost-per-hour performance. The answer? Cat Abrasion™. A direct replacement for SystemOne™, Cat Abrasion performs better and lasts 50% longer than conventional undercarriage* in high-abrasion, low-to-medium impact applications.
