Komatsu D51i-24 (131 hp) and D61i-24 (168 hp) dozers are now available with Komatsu’s intelligent Machine Control (iMC) technology. According to the company, the iMC 2.0 system can help quickly transform construction job sites into highly efficient, highly productive operations.
iMC incorporates a host of advanced machine controls, software and components. For example, 3D design data is fully integrated into the machine and guides the operator’s work. The iMC monitor uses a large touchscreen with a simple screen layout that displays the necessary information in an easily understood fashion. And stroke-sensing hydraulic cylinders provide real-time position that is immediately displayed to the operator. This is reportedly an improvement over conventional aftermarket machine guidance (indicate only) systems with tilt sensors.
The technology lets contractors take advantage of productivity-enhancing automation and cutting-edge job site design. No longer does an operator need to look to a grade checker/laborer or ground stakes for guidance on where to move the earth. Operators — even those with limited experience — can work at high efficiency, guided by sophisticated automation.
Among the benefits:
Learns as it works. With proactive dozing control, drivers can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Productivity can reportedly improve by up to 60% versus the previous generation.
Spreads fill material automatically. Lift layer control automatically lets operators spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over and uses the data it gathers to plan the next pass for up to double production with consistent layers for compaction quality.
Levels during rough dozing. Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. This is said to reduce operator steering input by up to 80%.
Quick surface creation. Operators can 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.
From automatic dozing, rough cut to finish grade, iMC-equipped dozers improve production compared to traditional aftermarket systems, said the company.
