Key Specs
To keep your business on firm footing, you need undercarriage systems and components that propel your machines over any type of terrain— and through every operational challenge. Leveraging decades of experience in mining, excavation and material handling, the Cat® brand utilizes its storied industry roots to deliver high productivity, durability and reliability. And to ensure the proper fit, our team of engineers will work with you to choose the right undercarriage for your application that will help yield low operating costs, long service life and great value.
Undercarriage typically represents an average 50% of a machine’s owning and operating costs, so it makes sense to invest in a system that will deliver the most value.
Our hydraulically-powered, variable gauge undercarriages offer 2 positions: extended & retracted. The retracted footprint minimizes the machine’s footprint for transportation while the extended position provides stability at work.
Our undercarriages are designed to synch with Cat uppers. Every component meets strict specifications and quality standards that no competitor can match while durable, reliable components result in lower operating costs.
