Komatsu America Corp. introduced the highly successful Parallel Link Undercarriage System (PLUS) option to the D155AX-8 dozer on July 30.

The PLUS system is designed to provide up to twice the life of a conventional undercarriage, lowering repair and maintenance costs by up to 40 percent in certain applications. PLUS also eliminates the downtime of pin and bushing turns. All PLUS undercarriage components are designed for equal wear life.

PLUS uses oil lubricated, rotating bushings that are free to rotate, unlike fixed bushings used on conventional undercarriage systems.

The rotating bushing undercarriage option will be great addition to its predecessor, Komatsu America Product Manager Chuck Murawski said.

“Applications for PLUS undercarriage range from high-impact, rocky ground conditions to low-impact, abrasive sandy worksites,” Murawski said. “This has enabled PLUS to become standard equipment on other Komatsu dozer models.” 

Each of the three shoe widths available – 24 inch (610mm), 26 inch (660mm) and 28 inch (710mm) PLUS ES shoes - are made with extreme service shoes for maximum wear life and durability.

Komatsu America is a U.S. subsidiary of Komatsu, Ltd., the world’s second largest manufacturer and supplier of earth-moving equipment, including construction, mining and compact construction equipment. Komatsu America also serves the forklift and forestry markets.
