See page 10.
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.
Large Digging Force
With the addition of one-touch Power Max. function digging
force has been further increased. (8.5 seconds of operation)
Maximum arm crowd force (ISO):
228 kN (23.3t) 246 kN (25.1t)
(with Power Max.)
Maximum bucket digging force (ISO):
294 kN (30.0t) 317 kN (32.3t)
(with Power Max.)
Lifting Mode
When lifting mode is selected, lifting capacity increases 17%
by raising hydraulic pressure. The work equipment and
swing speeds are lowered at the same time to provide
additional control.
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.

Hydraulics
Unique two-pump system assures smooth compound movement of the
work equipment. OLSS (Open Center Load Sensing System) controls all
pumps for efficient engine power use. This system also reduces hydraulic
loss during operation.
Power and Economy Mode
The PC600-8 excavator is equipped with two working modes. Each mode
is designed to match engine speed, pump speed, and system pressure to
the current application, giving the operator flexibility to match equipment
performance to the job at hand.

Environment-friendly Clean Engine Mounted
The PC600-8, which is equipped with the Komatsu
SAA6D140E-5 engine, meets the Tier 3 emission
regulations in the North America (EPA) and EU stage 3A.
The SAA6D140E-5 engine adopts the world’s first cooled
EGR system with electronically controlled bypass-assist type
venturi to reduce NOx emission 40% , while maintaining the
high power and low fuel consumption.
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
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.

Strengthened Quarry Bucket for Provides Outstanding Wear-resistance (optional)
The bucket for specific use in quarry is impact and wear resistant, providing high performance and long life.
Koma-hard materials* provide excellent wear resistance. Combined with adoption of long-life KMAX tooth, durability of bucket
is drastically enhanced.
* Koma-hard materials (KVX materials):
Komatsu developed, wear-resistant, reinforced materials.
Brinell hardness: 500 or more (180kgf/mm
2
class).
Features high wear-resistance and little quality change by
the heat generated during rock loading, maintaining the
hardness for a long term.
Excellent Reliability and Durability
Strengthened Boom and Arm
Thanks to the large cross-sectional
structure employing a high tensile
strength steel with a thick plate,
partition wall, etc., the boom and arm
exhibit excellent durability and are
highly resistant to bending and
torsional stress.
Metal Guard Rings
Metal guard rings protect all the
hydraulic cylinders and improve
reliability.
Sturdy guards shield the travel motors
and piping against damage from rocks.
(Rock protectors are optional.)
Strengthened Revolving Frame
Underguard
Guards the machine body against
being hit by rocks from below and
prevents hydraulic components and
the engine from being damaged.
High-pressure In-line Filtration
The PC600-8 has the most extensive
filtration system available, providing inline filters as standard equipment. An
in-line filter in the outlet port of each
main hydraulic pump reduces failures
caused by contamination.

O-ring Face Seal
The hydraulic hose seal method has
been changed from a conventional
taper seal to an O-ring seal. This
provides improved sealing performance
during operation.
Frame Structure
The revolving frame mount and center
frame mount on the swing circle are no
welding structure so that force is
transmitted directly to the thick plate of
the frame without passing through any
welding.
Fuel Pre-filter
(with Water Separator)
Removes water and contaminants from
in the fuel to enhance the fuel system
reliability.
Sturdy Undercarriage
The undercarriage is strengthened to
provide excellent reliability and
durability when working on rocky
ground or blasted rock.
