temperature, and varies the engine output
depending on the fan speed.
On-demand power control system
Controls pump absorbing horsepower
and engine output automatically
according to the job.
All-out power delivery system
Outputs all-out engine power when the
heavy lift mode and travel is selected.
Komatsu Technology
Komatsu develops and produces all major
components, such as engines, electronics
and hydraulic components, in house.
With this “Komatsu Technology” and adding
customer feedback, Komatsu is achieving
great advancements in technology.
To achieve both high levels of productivity and
economical performance, Komatsu has
developed the main components with a total
control system. The result is a new generation
of high performance and economical
excavators.

In complete pursuit of total cost reduction and eco-friendliness
Evolutionary Komatsu technologies
Powerful and Fuel Efficient Machine
achieved by Total Power Management
PC2000-8 is equipped with the new Komatsu
SAA12V140E engine that features clean, fuel
efficient and powerful performance. Power
losses in hydraulic system, cooling fan and
PTO are reduced. Total Power Management
using On-demand Power Control System
succeeds in drastically reducing the fuel
consumption per hour. The machine has
enhanced functions that contribute to energy-
saving operation including adjustable ‘E
mode’ and ‘Eco-gauge’. PC2000-8 is a new
generation clean and economical machine.
High Power Komatsu Engine
713 kW (956 HP)
Equipped with the high efficiency
turbocharger with large air-to-air
aftercooler, the engine delivers high
output of 713 kW (956 HP). The ample
engine power enables an increase in
work efficiency. The clean engine is
Tier 2 emission certified in USA (EPA).
Heavy Lift Mode
Turning the heavy lift mode switch on
activates the all-out power delivery
system to increase the lifting force of
the boom. This mode is beneficial
when handling rock and during heavy
lifting applications.
Advanced Environmentally
Friendly Features
Eco-gauge
The Eco-gauge is provided on the right
side of the monitor screen for energy
saving operation. The gauge informs
the operator of cumulative achievement
to a predetermined fuel consumption
target. By keeping the gauge indication
within the green range, the operator
can perform fuel-efficient operation to
meet the target value.
Idling caution
To prevent unnecessary fuel
consumption, an idling caution is
displayed on the monitor when the
engine idles for 5 minutes or more.
Auto deceleration and auto idling
system
The machine is equipped with the auto
deceleration system (1400 rpm),
reducing operating noise as well as
fuel consumption. The auto idling
system enables the engine idling
speed to be set at a lower speed.
Power module packaging for ultra
low-noise operation
Noise sources such as the engine,
cooling fan, and hydraulic pumps are
packaged in the machinery house.
Large sound absorbing blades
attached on the air intake and exhaust
outlet block noise transmission.
Combined with the three dimensions
hybrid cooling fan, the machine
realizes environmently-friendly
operation with amazingly low-noise.
Selectable Working Modes
Two established work modes are
further improved. You can select
Power or Economy modes using a
one-touch operation on the monitor
panel depending on workloads.
Two E mode settings available,
enabling the operator to select
optimum mode that delivers the best
combination of production and fuel
efficiency considering working
conditions.
Eco-gauge
Fuel consumption at E mode 10% reduced
Compared with the PC1800-6 at DH mode and
100% working efficiency.
Fuel consumption varies depending on job
conditions.
