What to Know About Cat® Dozer Undercarriages

Some of the world’s toughest jobs are on mine sites. And if your dozer’s undercarriage isn’t up to the task, work will quickly grind to a halt. Your Cat® dozer undercarriage works and wears as a system, ensuring longer service life, increased uptime and lower costs.

Every Cat® mining dozer undercarriage is built to meet the rigorous demands of mine sites. The components are integrated with the machine and work together seamlessly. They’re field-tested for proven durability and reduced maintenance. That means maximum performance at the lowest cost — so you can move more materials, more efficiently.

The undercarriage represents on average 50% of your dozer’s owning and operating costs. Cat undercarriage components wear at a balanced rate, giving you longer life with predictable downtime and lower repair costs over the life of your bulldozer.

Designed based on years of field experience, a Cat general duty undercarriage is recommended for low-to-moderate impact applications. There’s also a heavy duty undercarriage system for hard rock applications with moderate-to-high impact levels. The components are interchangeable, which cuts the need for retrofitting and minimizes downtime.

When operated and maintained properly, Cat general duty undercarriages deliver value and performance. And the data from Cat dealers and customers proves it.

 

THE POWER OF CATERPILLAR IN ACTION

Let’s look at a diamond mine that had been buying a competitor undercarriage for their Cat D9 Dozers. To lower operating costs, the mine’s Cat dealer recommended the Cat general duty system with an undercarriage management program.

The customer conducted a trial on two of their D9 dozers, while the dealer monitored undercarriage performance. After collecting 6,000 hours of data, they saw that the Cat general duty undercarriage cost 10% lower per hour than the competitor undercarriage. That meant savings of more than $10,000 each year. The decision was simple for this diamond mine. They switched to Caterpillar. 

 

SLEEVE BEARING TRACK FOR PROVEN PERFORMANCE

The patented sleeve bearing track is standard on all D11 dozers and has more than 10 years of proven field performance. The sleeve bearing track eliminates galling, increasing track performance so your machines can keep working. It is designed to run at higher speeds while handling greater loads.

Bushings have a special coating to improve seal life, and the sleeve bearings are made of hardened steel. The track’s overall durability reduces maintenance costs and unscheduled downtime.

 

POSITIVE PIN RETENTION DESIGN FOR MAXIMUM DURABILITY

Available for D9-D11 dozers, the positive pin retention (PPR) track features specially machined links and pins that allow for the use of a metal retaining ring.

This ring fits in the groove between the pin and link, locking the joint to a predetermined specification. It prevents the outward movement (also known as end-play generation) of the links on the pin. The result is more uptime and increased productivity for your business.

 

ASSURANCE FOR THE LONG HAUL

The Cat Undercarriage Assurance Program gives you extended support for your undercarriage. Your Cat dealer will make sure you have service and support beyond the standard new machine or parts warranties. The program covers all major moving undercarriage components and can be customized to meet your needs.
