Cat Undercarriage Choices
for Mining

All Cat undercarriage works and wears as a system, ensuring a balanced wear life. That means significantly lower owning and operating costs, increased uptime, reduced maintenance intervals, more productivity and longer service life.

Undercarriage Choices for Construction Equipment

General Duty Undercarriage

General Duty undercarriage is recommended for low-to-moderate impact applications where the elevated performance of Cat Heavy Duty Undercarriage is not needed. While General Duty track is built to different specifications than Heavy Duty, we design it so General Duty and Heavy Duty components are interchangeable to eliminate retrofits and keep downtime to a minimum. Available for D9-D11 dozers.
