Komatsu’s Proactive Dozing Control Logic Automates 100% Of Operations

Four Komatsu crawler dozers now have an advanced, new automated control option called Proactive Dozing Control logic. Building on the manufacturer’s “straight-to-grade” Intelligent Machine Control system, which automates finish grading, the new development brings automation to stripping, spreading, and high-production dozing operations as well.

“Traditionally, GPS machine control focused on finish grade, which meant operators only used the technology approximately 10 to 20% of the time,” says Komatsu’s Product Marketing Manager for Intelligent Machine Control and Smart Construction, Derek Morris. “Proactive Dozing Control logic is a game-changer because the integrated system now lets operators use automation anytime, whether for general site cleanup, backfilling trenches, and more.”

The new technology is available on Komatsu’s 15-ton (13.6-metric-ton) D51EXi-24, 16-ton (14.5-metric-ton) D51PXi-24, 20.5-ton (18.6-metric-ton) D61EXi-24, and 21.5-ton (19.5-metric-ton) D61PXi-24 tracked dozers.

“A Game-Changer”

Komatsu’s new Proactive Dozing Control logic uses GNSS (the Global Navigation Satellite System), an IMU (Inertial Measurement Unit), and cylinder sensors to ascertain the dozer and blade’s relation to the terrain as the latter changes during operation. It can decide whether to tell the dozer to automatically cut and carry material, spread or fill it, or finish grade, Komatsu says.

“A key differentiator is that our system collects data at the tracks, while aftermarket solutions collect data at the blade,” said Morris. “Because data is collected at the track, the system provides a real-time picture of the ground around the machine, allowing the system to make calculated decisions based on the current terrain.”

Proactive Dozing Control logic also minimizes track slip to reduce wear on the undercarriage, which is a major cost center of any crawler dozer.

“We’ve created machine control that is far more advanced, offering an entirely new level of efficiency,” Morris said. “Whether you’re an operator who has 20 years’ experience or someone new to the job, our Proactive Dozing Control logic provides precision work every time, making operation easier and more productive.”
