Komatsu America Corp., has made its PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage an option for the D155AX-8 dozer.
“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.”
Each 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 maximum wear life and durability. 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.
To give machine owners added peace of mind, the PLUS undercarriage assurance program covers leakage and breakage due to defects in material or workmanship for 3 years or 4,0000 hours, whichever occurs first. Local Komatsu America distributors also offer supplemental wear-life coverage.
Additionally, the D155AX-8 dozer and every other Komatsu Tier 4 Final construction-sized machine, whether rented, leased or purchased, is covered by the Komatsu CARE program for the first three years or 2,000 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.
