The Innovative PLUS System of the Komatsu Dozer

Komatsu America has added the Parallel Link Undercarriage System, PLUS, to another of the company’s heavy equipment models, the D85EX/PX-18 dozer. This option uses a rotating bushing undercarriage option that reduces downtime and maintenance expenses by providing up to twice as much wear life when compared to existing fixed bushing systems.

This innovative track technology works well on both high-impact terrain such as rocky ground, and low impact conditions such as sand. “This leading-edge track technology is quickly becoming standard equipment on several Komatsu dozer models,” said Chuck Murawski, product manager, Komatsu America.

PLUS is available on three shoe width sizes, 24”/610mm, 26”/660mm and 28”/710mm, using extreme condition shoes for extended wear life and more durable activity. Compared to industry standard undercarriage systems, PLUS can reduce the cost of repair and maintenance by as much as 40 percent. Since the rotating bushings do not require regular pin and bushing turns, including a special design for equal wear, there is less downtime when maintenance is required.

This is a major improvement over older undercarriage styles which use fixed bushings. PLUS system use independently rotating oil lubricated bushings instead, offering longer wear and less breakage.

With Komatsu’s unique assurance program, leaks and breakage are covered for up to 3 years or 4000 work-hours. For additional coverage, a supplemental wear-life program is also available. Komatsu provides even more protection for their heavy equipment, including the Komatsu Tier 4 construction machines such as the Komatsu dozer, D85EX/PX-18. This coverage, the Komatsu CARE® program, is valid during the first 3 years of ownership, up to 2000 hours, and includes scheduled maintenance, an extensive 50-point inspection, and two Komatsu Particulate filter changes, as well as DEF tank flushes during the initial 5 years of ownership.

The Komatsu dozer and other heavy equipment with the PLUS option are well suited for construction, mining, forestry and other intensive operations.
