Cat Undercarriage: Optimized for Your Application.

Cat undercarriage is factory and field tested. Tests have shown that Cat undercarriage delivers up to 2 times the life of competitive undercarriage. Let us help you determine the best solution for your operation.

Because Caterpillar manufactures its own undercarriage, every component meets strict specifications and quality standards that no competitor can match. Durable, reliable components result in lower operating costs.

Caterpillar engineers understand how application demands wear undercarriage components. They design undercarriage as a system. Each one is built to take on specific conditions such as sand, gravel, mud and clay.

The weight of a machine is very important in determining undercarriage size. The size of undercarriage components used on a tractor is not necessarily the same size that should be used on a different type of machine of similar size and weight.

Most OEM applications are slow speed (3.5 mph or less) and would be best served by using hydraulic excavator undercarriage arrangements. Generally applications above 3.5 mph are best served with crawler tractor arrangements.

Undercarriage life is determined, in part, by the operating environment, normal and maximum operating speeds, and job function. Regardless of the machine’s function, proper design and service can extend the life of the undercarriage.
