Intelligent machine control the focus for Doosan, Komatsu equipment
Two construction-equipment manufacturers
target increased productivity with
their products by recently enhancing
their machine-control features. Doosan
Infracore North America now will offer
the Trimble Earthworks Grade Control
Platform for Excavators as an optional
factory-installed grade-control solution
for the North American market. Trimble
Earthworks is designed to make grading
faster and more accurate in a range of
applications, including residential and
commercial sites, trenches, embankments,
ditches and finished slope work.
" Doosan crawler excavator customers
can enhance their trenching accuracy
with the increased technology,
contributing to an improved ROI. And
our dealers can now offer this directly
from the factory to our customers, "
said Jaeuk Kim, Doosan director of
product management.
Doosan will offer integrated 2D
grade control with automatics that includes
a 10-inch Android tablet display
running the Earthworks software application.
It also includes Trimble hardware
designed for harsh conditions.
When the excavator is placed in
Automatics mode, the operator controls
the stick and Trimble Earthworks
controls the boom and bucket to stay
on grade, reducing overcut and increasing
production.
By automating excavator operation,
Trimble Earthworks can allow operators
of Doosan crawler excavators to achieve
grade with high accuracy and in less time.
Contractors can work with a Doosan
dealer to upgrade their 2D system to 3D
through a SITECH dealer. SITECH is
Trimble's global distribution network
that provides installation services, training
and technical support.
Enhanced automation also is the
highlight of Komatsu's " smallest intelligent
dozer, " the D39i-24. With intelligent
Machine Control (iMC 2.0), 3D
design data can be programmed directly
into the 105-hp (78-kW) machine.
The factory-installed automatic dozing
improves operators' productivity from
rough cut to finish grade.
The integrated system upgrades the
D39i-24 with new intelligent features.
With proactive dozing control, the dozer
measures the terrain it tracks over
and uses that data to plan the next pass
so even less-experienced operators can
automatically cut/strip from existing
terrain. Productivity can improve by up
to 60% compared to the previous generation,
according to Komatsu.
The system spreads fill material automatically.
With the press of a button, lift
layer control puts in repeated consistent
lifts. Time savings are realized, Komatsu
said, by reducing or eliminating the
need to rework for over-compaction or
under-compaction. Operators also can
create a temporary design surface at
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.
Reduced operator fatigue is another
Komatsu's " smallest intelligent dozer, " the D39i-24 incorporates automatic dozing features that can
improve productivity by up to 60% versus the previous generation.

stated benefit. Tilt steering control automatically
tilts the blade to maintain
straight travel during rough dozing,
reducing operator steering input by up
to 80%.
