Komatsu Introduces PLUS Undercarriage Option for D155AX-8 Dozer

August 7, 2015

Komatsu has added its PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage option to the D155AX-8 crawler dozer.

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 eliminates the downtime of pin and bushing turns, and all its undercarriage components are designed for equal wear life.

PLUS uses oil-lubricated, rotating bushings that are free to rotate. Applications for the undercarriage range from high-impact, rocky ground conditions to low-impact, abrasive sandy work sites.
