Komatsu Introduces Parallel Link Undercarriage System (PLUS) For D85EX/PX-18

September 21, 2015

Komatsu's PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage is now available as an option on D85EX/PX-18 dozers.

Each of the three different shoe widths are available: 24, 26 and 28 inches. 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, Komatsu says. PLUS also eliminates the downtime of pin and bushing turns. All 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.

Additionally, the PLUS undercarriage assurance program covers leakage and breakage due to defects in material or workmanship for 3 years or 4,000 hours, whichever occurs first.
