The new Komatsu D39i-24 dozer offers enhanced automation

Komatsu dozer

Komatsu has introduced its new D39i-24 dozer, the manufacturer’s smallest dozer to offer intelligent Machine Control 2.0 (iMC). 

The 9,910 kg dozer allows its user to program 3D design data directly into the 105 hp machine. 

Operators — even those with less experience — can work with utmost efficiency, guided by sophisticated automation. Through automatic dozing, Komatsu’s iMC 2.0-equipped D39i-24 helps make every pass more accurate for improved production.

With a factory-installed, integrated system, the D39i-24 has been upgraded with a number of new intelligent features. 

The dozer is capable of learning as it works. With Proactive Dozing Control, the dozer measures the terrain it tracks over and uses that data to plan the next pass so even less experienced operators can automatically cut and strip from existing terrain. Productivity can improve by up to 60 per cent compared to previous generations.

In rough dozing, the Komatsu D39i-24 dozer is also able to reduce operator fatigue. For example, tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80 per cent.

To spread fill material automatically, with the press of a button, lift layer control puts in repeated consistent lifts. Time savings are realized as each layer is precise, reducing or eliminating the need to rework for over compaction or under compaction.

As well, operators are able 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 dozer is equipped with a dual-path, hydrostatic transmission that provides infinite speed changes up to 5.3 km per hour. The variable capacity travel motors allow the operator to select the optimum speed to match specific jobs.
