Komatsu’s 11-ton (10-metric-ton)-class D39i-24 has become the manufacturer’s smallest dozer with Intelligent Machine Control 2.0 technologies. The iMC 2.0 system partially automates the grading process to help operators work from rough cut to finish grade quickly and accurately. The 105-net horsepower (78-kilowatt) dozer has a blade capacity of 2.89 to 3.14 cubic yards (2.2 to 2.4 cubic meters).
Intelligent Machine Control 2.0
The iMC 2.0 system is factory-installed and integrated with the D39i-24, so there is no Global Navigation Satellite System (GNSS) antenna, mast, or cable attached to the blade. Its multiple automation technologies serve to “make every pass count,” Komatsu says, even with a less experienced operator.
With iMC 2.0, the user can program 3D design data directly into the dozer. The system’s proactive dozing control “learns as it works” by measuring the terrain under its tracks and then plotting out settings for the next pass. This improves productivity up to 60% over Komatsu’s previous-generation product, the company says.
Komatsu’s iMC 2.0 also automatically tilts the blade to maintain straight travel and level material even during rough dozing. This tilt steering control reduces operator steering input by up to 80%, the manufacturer says, which serves to reduce driver fatigue.
The iMC 2.0 system can also spread fill material automatically using lift layer control with little worry of over- or under-compaction. The operator can press a button to create a temporary design surface, allowing the work crew to start automated stripping or spreading before the finish grade model arrives. The iMC 2.0 technology can automate nearly 100% of the machine control in tasks such as auto stripping, rough dozing, spreading, and advanced finish grading. It can even provide automatic control without a 3D model, according to Komatsu.
The Komatsu D39i-24
The D39EXi-24 is the standard undercarriage version of the D39i-24 design with an operating weight of approximately 21,848 pounds (9,910 kilograms). The low-ground-pressure D39PXi-24 edition weighs in at 22,774 lbs (10,330 kg).
All variants of the D39i-24 dozer have a 3.26-liter, four-cylinder, Komatsu diesel engine with a variable geometry turbo and Tier 4 Final emissions compliance. An electronically controlled hydrostatic transmission smooths out the crawler’s turns.
The operator uses Komatsu’s Palm Command Control System (PCCS) joystick control to steer the dozer and set it in motion. The machine can travel at up to 5.3 mph (8.5 km/h). Both tracks receive full power during turns and counter-rotation steering. The D39i-24 also features a fast-blade mode that increases blade speed during high-speed grading.
