Komatsu’s D39i-24 dozer now has intelligent Machine Control

Komatsu introduces its intelligent Machine Control for the D39i-24, its smallest intelligent dozer, allowing users to program 3D design data directly into the machine.
With iMC 2.0, even operators with less experience can work with high efficiency, guided by sophisticated automation. “Through automatic dozing, rough cut to finish grade, Komatsu’s iMC 2.0-equipped D39i-24 helps make every pass count for superior production, compared to traditional aftermarket systems,” Komatsu said.
With a factory-installed, integrated system, the 105-horsepower, 22,000-lb D39i-24 has been upgraded with a number of new intelligent features.
Proactive dozing control enables the dozer to measure the terrain it tracks over and use that data to plan the next pass so even less-experienced operators can automatically cut/strip from existing terrain. Productivity can improve by up to 60% versus previous generation, the company said.
Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80%.
Lift layer control puts in repeated consistent lifts with the press of a button. Time savings are realized because each layer is precise, reducing or eliminating the need to rework for over compaction or under compaction.
Quick surface creation gives operators the ability to create a temporary design surface with the press of a button with quick surface creation. Combined with other iMC 2.0 functions, crews can begin stripping or spreading using automated input while waiting for the finish grade model.
The D39i-24 joins Komatsu’s family of 10 small dozers ranging in operating weight from 20,500 to 31,400 lbs.
In February, Komatsu introduced the new 237-horsepower D71EX/PX-24 dozer with a distinctive slant-nose design and intelligent Machine Control.
