Komatsu Adds Undercarriage Option to D155AX-8 Dozer

Komatsu America Corp. now offers its PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage option to the D155AX-8 dozer. The undercarriage offers up to twice the wear life, reducing downtime, repair and maintenance costs, according to the company. 

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

PLUSEach of the three different shoe widths available – 24-in/610mm, 26-in./660mm and 28-in./710mm PLUS ES shoes - are made with extreme service shoes for wear life and durability. The PLUS system can lower 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 PLUS undercarriage assurance program covers leakage and breakage due to defects in material or workmanship for 3 yrs/4000 hours, whichever occurs first. Local Komatsu America distributors also offer supplemental wear-life coverage.

Komatsu Tier 4 Final construction-sized machine are covered by the Komatsu CARE program for the first three years or 2000 hours, whichever comes first. Komatsu CARE includes scheduled factory maintenance, a 50-point inspection at each service and two complimentary Komatsu Diesel Particulate Filter exchanges and DEF tank flushes in the first five years.
