Komatsu unveils Parallel Link Undercarriage System
“PLUS undercarriage cuts maintenance costs, extends wear life and excels in high-impact, rocky ground conditions and on low-impact, sandy jobsites,” Komatsu Product Manager Chuck Murawski said. “This leading-edge track technology is quickly becoming standard equipment on several Komatsu dozer models."
The three different shoe widths available – 24-inch, 26-inch and 28-inch PLUS ES shoes -- are made with extreme service shoes for maximum wear life and durability.
The PLUS system is also 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, according to Murawski, who said PLUS also eliminates the downtime of pin and bushing turns. All PLUS undercarriage components are designed for equal wear life.
And PLUS uses oil-lubricated, rotating bushings that are free to rotate, unlike fixed bushings used on conventional undercarriage systems. Additionally, the PLUS undercarriage assurance program covers leakage and breakage due to defects in material or workmanship for three years or 4,000 hours, whichever occurs first.
