The new dozer also features Komatsu’s proprie-
tary KOMTRAX (Komatsu Machine Tracking System)
and TOPCON’s construction management system.
In the near future, this integrated system will
enable high-efficiency, unified management of con-
struction work through access to realtime machine
data, via its web service, to track work progress in-
cluding the amount of soil dozed at jobsites.
Fully Automatic Blade Control for
Rough and Fine Dozing
While high-precision finish grading can be achieved
by crawler dozers equipped with a conventional
control system, the D61i-EXi can also perform
rough dozing in automatic mode, thanks to a fully
automatic blade load control.
When rough dozing, the automatic blade control
monitors blade load and adjusts blade elevation, to
minimize track slip and deliver high-efficiency doz-
ing. As work progresses closer to the target finish
grade, the automatic blade control adjusts accord-
ingly to provide finish grade performance with high-
Komatsu claim that when compared to conven-
tional add-on machine control systems, an increase
of up to 13% in efficiency can be achieved when
using Komatsu’s technological innovation in rough
Standard Factory Installed and
Komatsu hasmoved away from add-on components
for the machine control system that were typically
mounted on the blade. With the new model, it is
a fully-integrated system within, and protected by,
the cab structure.
These components are installed at the Komatsu
manufacturing facility during machine assembly,
along with the machine control monitor and con-
trollers mounted inside the cab.
The integrated sensor package is not only robust
and accurate but also eliminates the daily hassles of
installing and removing GNSS antennas and cables
from the blade, and the wear associated with it.
Enhancements for Optimized
Inside the cab, selectable dozing modes allow the
system response to be tailored to current machine
operations, for optimized performance. Similarly,
blade load settings are adjustable between presets
to match actual material conditions.
From pass to pass, the intelligent Machine Con-
trol system can be left with the automatic blade
control engaged because of its ability to precisely
automate the lowering of the blade at the start of a
pass and raise it at the end.
When the machine travels around the job site,
the cab top GNSS antenna collects accurate surface
data by measuring actual elevations.
The stroke sensing angle cylinder measures the
actual angle of the blade for high precision grad-
ing accuracy on cross-slope with the blade angled
