Komatsu's Proactive Dozing Control logic is integrated 100 percent of the time for boost in productivity

Industry-first helps operators deliver precision work

"Proactive Dozing Control logic opens up a world of application possibilities for machine control technology," said Derek Morris, Product Marketing Manager, Intelligent Machine Control and Smart Construction for Komatsu.
"Proactive Dozing Control logic opens up a world of application possibilities for machine control technology," said Derek Morris, Product Marketing Manager, Intelligent Machine Control and Smart Construction for Komatsu.

Komatsu America Corp. recently introduced its Proactive Dozing Control logic, a fully integrated dozing control system that allows operators to perform auto-stripping, auto-spreading and high-production dozing, as well as finish grading. Available on the Komatsu D51EXi-24, D51PXi-24, D61EXi-24 and D61PXi-24 dozers, Komatsu's Proactive Dozing Control logic is built on the company's existing intelligent machine control.

"Proactive Dozing Control logic opens up a world of application possibilities for machine control technology," said Derek Morris, Product Marketing Manager, Intelligent Machine Control and Smart Construction for Komatsu. "Traditionally, GPS machine control focused on finish grade, which meant operators only used the technology approximately 10 to 20 percent of the time. Proactive Dozing Control logic is a game-changer because the integrated system now lets operators use automation any time, whether for general site cleanup, backfilling trenches and more."

The machine control system communicates with the dozer's hydraulic controllers, engine controllers and the machine controller.

How does Proactive Dozing Control logic work?

The system uses Global Navigation Satellite System (GNSS) positioning in conjunction with an Inertial Measurement Unit (IMU) to calculate precise position. The two sensors work together to calculate exactly where the tracks are on the ground.

The machine control system communicates with the dozer's hydraulic controllers, engine controllers and the machine controller. Through cylinder sensor technology, the position of the blade is calculated in relationship to the machine body. The Proactive Dozing Control logic measures the surrounding ground and determines what has been done on the area being graded, then stores that data and information. When the dozer prepares to go back over that area to cut or work it more, the system understands what it was like from its previous track and therefore, follows the existing terrain – the very terrain that was just created.

Proactive Dozing Control logic provides real-time position of the machine on the jobsite to create a highly accurate elevation for the system to drive the blade to the precise grade needed. Using real-time conditions, the system understands what the terrain around the machine looks like and makes calculated decisions – whether it should cut and carry material, whether it should spread or fill that material, or whether it should be finish grading. 

“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.”

"A key differentiator is that our system collects data at the tracks, while aftermarket solutions collect data at the blade," Morris noted. "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." Morris continued, "By collecting data at the track level, we've created machine control that is far more advanced, offering an entirely new level of efficiency, 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."

Reduce owning and operating costs and boost productivity

With Komatsu's Proactive Dozing Control logic, operators can use the dozer to its full capacity, leading to increased utilization, better ROI and better production. Owning and operating costs are also lowered because wear and tear on the machine is reduced by automating operation. By significantly minimizing track slip during operation, undercarriage wear is reduced, thereby lowering O&O costs, since 50 percent of the ownership cost of a dozer is the undercarriage.

Pushing precision: an in-depth report on dozers

It used to be that contractors would use crawler dozers for a very specific type of job: pushing a whole lot of dirt in a short amount of time. They are a workhorse for cutting down to grade, even today, but with advancements in technology owners are using these powerful machines for much finer detail work than ever before. We asked our industry experts to tell us how the dozer landscape is changing and how pushing dirt has turned into much more.

Watch JCB's first electric compact excavator do the bottle cap challenge

The bottle cap challenge is the latest internet sensation and involves performing a precise roundhouse kick to spin the cap off a bottle without knocking the bottle over. It was started by Farabi Davletchin, a Kazakh Taekwondo champion, who then challenged action stars such as Jason Statham to give it a go – and now all the kids are doing it. Not to be left out of the silliness, JCB has gotten in on the fun with its first electric compact excavator performing the stunt.
