Working Mode Selection
Power and Economy Mode
The PC800-8R excavator is equipped with two working
modes. Each mode is designed to match engine speed,
pump flow, and system pressure to the current application,
giving the operator flexibility to match equipment performance
to the job at hand.
High Power Komatsu SAA6D140E Engine
Powerful turbocharged and air-to-air aftercooled Komatsu
SAA6D140E-5 engine provides 363 kW 487 HP.
This Komatsu SAA6D140E engine actualizes high-power to
low fuel consumption with the optimum fuel injection by
electronic heavy duty HPCR (High Pressure Common Rail)
fuel injection system.
Electronically Controlled Variable Speed Fan
Contributes to Low Fuel Consumption and Low
Noise
The electronic control system sets
the rotational speed of the cooling fan
according to the coolant, hydraulic oil,
and ambient temperature; effectively
uses the engine output to prevent
wasteful fuel consumption; and
reduces noise during low-speed fan
rotation.
Lower and Economical Fuel
Consumption Using
Economy Mode
Enables operator to set the Eco
mode to up to four levels
according to working conditions
so that production requirement is
achieved at lowest possible fuel consumption.
Reduction of Ambient Noise (optional)
Reduced noise by adoption of an electronically controlled
variable speed fan drive, large hybrid fan, low-noise muffler
and cover with glasswool, to meet EU Stage 2 noise
regulations.

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 environment friendly
excavators.

Result
Oil flow to the swing motor is increased.
180˚loading operations are most efficient.
Oil flow to the boom is increased.
90˚loading operations are most efficient.
Heavy Lift Mode
Gives the operator 10% more lifting force on the boom when
needed for handling rock or heavy lifting applications.
Swing Priority Setting
The swing priority setting allows the operator to use the same
easy motion for 180˚ loading as 90˚ loading operations. By
altering the oil flow, this setting allows you to select either
boom or swing as the priority for increased production.

Large Digging Force
Thanks to the high engine output and an excellent hydraulic
system, this machine demonstrates powerful digging force.
Maximum arm crowd force (ISO):
250 kN 25.5 ton
Maximum bucket digging force (ISO):
333 kN 34.0 ton
Work Equipment Speed Increased
An arm quick return circuit is provided for arm dumping. This
returns a portion of oil flow directly to the hydraulic tank at
arm dumping to reduce the hydraulic pressure loss.
Combined with increased bucket dumping speed, faster
loading work is realized.
Large Drawbar Pull and Steering Force
Since the machine has a large drawbar pull and a high
steering force, it demonstrates excellent mobility even when
it is being used on inclined sites.
Two-mode Setting for Boom
Smooth mode provides easy operation for gathering
blasted rock and scraping operations. When maximum
digging force is needed, switch to power mode for more
effective excavating.
Shockless Boom Control
The PC800-8R boom circuit features a shockless valve
(double-check slow return valve) to automatically reduces
the amount of vibration present when operating the boom.
Operator fatigue is reduced (which can improve safety and
productivity), and spillage caused by vibration is minimized.
