Komatsu Australia has released the
PC210LCi-10, the world’s first Intelligent Machine Control (iMC) excavator,
which features a revolutionary and fully factory-integrated 3D GNSS machine
control and guidance system.
With an operating weight of 23.3
tonnes, the PC210LCi-10 is powered by a Komatsu SAA6D107E-2 diesel engine –
complying with US EPA Interim Tier 4 emissions requirements – rated at 123 kW.
Komatsu’s exclusive iMC concept is
designed to let operators focus on moving material efficiently, without having
to worry about digging too deep or damaging the target surface – and can result
in more than a 60% improvement in work efficiency when compared with
conventional construction processes.
According to Komatsu’s Aaron Marsh
– National Technology Solution Expert Manager, the PC210LCi-10 represents the
industry’s first move from conventional excavator machine “guidance” systems –
which require the operator to dig according to an in-cab indicate system – to
actual machine control automation.
“With conventional excavator
guidance systems, the final finish quality depends entirely on the skill of the
operator,” said Marsh.
“One of the biggest problems
customers have had with these systems is speed and accuracy from sensor lag and
100% operator inputs, so operators have had to constantly monitor the system to
check they are on design, while also having grade checkers regularly confirming
design surface accuracy.
“But with machine automation,
Komatsu’s iMC excavator enables operators to achieve optimum speed to final
grade accuracy with minimal operator inputs, while eliminating the need for
manual grade checking.”
From bulk excavation to finish
grading, the PC210LCi-10 excavator has been designed to drastically improve
efficiency and precision on work sites.
The new excavator’s iMC system, which
shares similarities with Komatsu’s recently launched intelligent dozer line,
offers real-time bucket edge positioning in relation to the machine and 3D
Key iMC components – all factory
installed and fully integrated into the machine – include:
stroke sensing hydraulic cylinders on the boom, arm and bucket, providing
real-time bucket position data sent to the in-cab control box, and
tracking the location of the cutting edge of the bucket relative to the
body of the machine and target surface
enhanced Inertial Measurement Unit (IMU+), located inside the machine, to
detect machine pitch and roll
12.1-inch machine control box inside the cab with easy to use touchscreen
functions; working from 3D project design files, it simultaneously
displays such information as magnified grading view, 3D view, current
as-built status, and the like
GNSS antennas, positioned on easily accessed handrails behind the cab,
plus a GNSS UHF digital II receiver located inside the machine.
“Due to factory integration of our
intelligent machine control components the only obvious sign that Komatsu
intelligent excavators are different from a standard machine are the antennas
and in-cab control box,” said Marsh.
“All other components are internal,
and highly secure from damage, vandalism and theft.”
As the PC210LCi-10’s bucket edge
approaches the target surface profile, the system’s machine control
capabilities come into play. These include:
grade assist, using the boom to adjust bucket height automatically as the
arm moves, allowing the bucket edge to trace the target surface and
stop control, which stops the machine during boom, arm or bucket operation
once the bucket edge reaches the target surface, again limiting
distance control, which controls the bucket by automatically selecting the
point on the bucket closest to the target surface, so even if the machine is
not facing a sloped surface at a right angle, it will still follow the
“Our new iMC excavator truly
represents the next generation in construction equipment technology,” said
“It brings the full benefits of the
machine guidance revolution we’ve seen over the past 10-15 years on excavators.
“For the first time we now see the next step in machine control evolution
moving from machine guidance to automation – a massive step forward for what is
the key piece of earthmoving equipment on any worksite.
“It delivers not only improved work
accuracy, but also improved construction efficiency, making every pass count.
“Jobs such as staking, survey and
even final inspection, which are usually completed manually, can be
significantly reduced by utilising the 3D design data held within the machine,”
“Studies by Komatsu have shown the
iMC excavator achieves up to a 63% reduction in construction time compared with
conventional staking/construction/inspection processes, and far greater
accuracy in finished surface levels.
“It also eliminates constant redo
work, ultimately reducing project costs,” he said.
In addition to its iMC
capabilities, the PC210LCi-10 incorporates a number of other cost-saving and
efficiency-enhancing features. These include:
SAA6D107E-2 engine, complying with US EPA Interim Tier 4 /EU Stage 3B
emissions requirements, providing exceptional performance while reducing
fuel consumption. Exhaust gas particulate matter (PM) reduced by more than
90% and nitrogen oxides (NOx) by more than 45% when compared with Tier 3
technology control system to better match engine output to hydraulic pump
requirements, resulting in up to 10% lower fuel consumption.
working modes including Attachment Economy and Power mode
