Undercarriage for Construction Equipment
MOVE MORE IN LESS TIME
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.
Our Latest Innovation: Cat® Abrasion™ Undercarriage
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 undercarriages* in high-abrasion, low-to-medium impact applications.
