Komatsu Introduces New Crawler Dozer

Komatsu's new D39PXi-24 crawler dozer features intelligent capabilities that eliminates the need to install and remove blade-mounted sensors each day, saving time and boosting productivity, the company says.

“With factory integration and a host of intelligent capabilities, the more owners of the D39PXi-24 run their machines, the more they save,” said Jason Anetsberger, Komatsu senior product manager. “The monthly production gains from starting sooner, finishing faster, using less fuel and saving on materials can add up quickly,” Anetsberger said.KOMATSU DOZER

Once engaged, the system automatically starts the cut and lowers the blade to grade in a typical dozing pass. If the load increases to a maximum, the blade automatically raises to minimize track slip to keep dozing productively. This intelligence achieves up to 8% greater efficiency in moving material, based on start-to-finish grade testing against typical aftermarket machine control systems.

New standard, operator-selectable, automatic reverse grading mode enables automatic blade control, while reversing to grade target surface, per customer feedback. A "Triple Labyrinth" final drive housing design provides additional protection for the final drive floating seals. 

The dozer's 3.26 L, 105 hp, Tier 4 final engine offers the same power, while increasing fuel efficiency with the addition of the Selective Catalytic Reduction (SCR) system and Diesel Exhaust Fluid (DEF). A new water cooled, Variable Flow Turbocharger, provides added durability and excellent engine response. The Komatsu DOC provides 100% passive regeneration and does not interfere with machine operation. New auto-idle shutdown helps reduce idle time and saves fuel.
