Evolutionary Komatsu technologies
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.
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
