Maximum Productivity
Powerful digging force
Shockless boom control
Thanks to the high engine output
and an optimised hydraulic system,
the PC800-8 delivers a powerful bucket digging force of up to
471 kN (48 tonnes) at PowerMax
and an arm crowd force of up to
374 kN (38,1 tonnes) at PowerMax.
The PC800-8 features a shockless
valve (double-check slow return
valve) that automatically reduces
the vibration level when operating the boom. Operator fatigue is
reduced - which can improve safety
and productivity- and spillage
caused by vibrations is minimised.
PowerMax
The PC800-8 is now equipped with
the one-touch PowerMax function
that gives you maximum digging
force when you need it most. It
increases standard digging force
by almost 10% and automatically
switches off after 8 seconds to
conserve fuel.
Swing priority mode
A twin swing motor system provides excellent swing performance,
with high speed and strong braking
power. The swing priority setting
allows using the same smooth motion for either 180° or 90° loading
operations. By altering the oil flow,
the operator selects either boom or
swing as the priority for increased
production.
Heavy lift mode
When handling rock or for heavy
lifting applications, the operator
can select the “heavy lift” mode to
gain 10% more lifting force on the
boom.
Two-mode boom control
Smooth mode
Boom floats upward, reducing lifting of machine front. This facilitates gathering blasted
rock and scraping down operations.
4
Power mode
Boom pushing force is increased, ditch
digging and box digging operation on hard
ground are improved.
5
Powerful and Environmentally Friendly
Low consumption ecot3
engine
Hydraulic drive radiator
cooling fan
Designed and manufactured by
Komatsu, the SAA6D140E-5 engine
provides high torque, a better
performance at low speed, and low
fuel consumption. With direct fuel
injection, turbocharger, common
rail air-to-air aftercooler and cooled
EGR system, productivity and
fuel efficiency are maximized. The
Komatsu SAA6D140E-5 engine is
certified for EU Stage IIIA emission
regulations.
The engine cooling fan rotation
speed is electronically controlled
and depends on the engine coolant
and the hydraulic oil temperatures:
the higher the temperature, the
faster the fan will turn. This system
increases fuel efficiency, reduces
the operating noise levels and
requires less horsepower than belt
driven fans.
Exceptional drawbar pull and
steering force
Regardless of the selected travel
speed, the final drives automatically
compensate for the load and give
maximum driving force whenever
needed. As a result, the PC800-8
generates exceptional drawbar pull
and steering force, giving smooth,
confident and safe machine movement.
Komatsu SAA6D140E-5
Eco-gauge and idle caution
The unique ECO-gauge helps the
operator reduce emissions and fuel
consumption for environmentally
friendly and energy saving operations. And to further avoid wasting fuel when the machine is not
actually working, a standard-fit idle
caution is displayed if the engine
idles for 5 minutes or more.
Variable speed fan
Eco-gauge
6
Less ambient noise
The PC800-8 is an exceptionally
powerful machine that maintains
low operating noise levels. In addition to the electronically-controlled
variable-speed fan drive, external
noise levels are further reduced to
meet EU Stage 2 noise regulations
by a low-noise glass wool furnished
muffler with cover, a hybrid fan, and
low-noise components.
Selectable working modes
The selectable “Power” or “Economy” modes are designed to match
the engine speed, pump speed and
system pressure to the current application. They give the operator the
flexibility to match the equipment
performance to the job at hand. The
Economy mode has 4 stages, for
an optimum combination of economy and production, while Power
Modes can be switched to reduce
fuel consumption where maximum
breakout force is not needed.
7
First-Class Operator Comfort
Wide spacious cab
Low noise design
The wide and spacious cab includes a newly designed heated air
suspension seat with a high backrest. The seat height and longitudinal inclination are easily adjusted
with a pull-up lever. You can also
set the operational posture of the
armrest and the position of the console or recline the seat all the way
and place it into a fully flat state
with the headrest attached.
Komatsu Dash 8 crawler excavators feature the lowest in-class
external noise levels and are
especially well-suited for work in
confined spaces or urban areas.
Reduced fan speed, a large capacity radiator, and the optimal usage
of sound insulation and of sound
absorbing materials help to make
noise levels inside Dash 8 excavators comparable to those inside an
executive car.
Pressurised cab
Cab damper mounting
An automatic air conditioner, an air
filter and a positive internal air pressure (60 Pa) combine to prevent
external dust from entering the cab.
The built-in stability of the Komatsu
PC800-8, combined with a highly
rigid deck and a sprung multi-layer
viscous mount system, drastically
reduces vibration levels for the
operator.
Automatic air conditioner
Storage compartment

Large, widescreen TFT
monitor
To enable safe, accurate and
smooth work, the user friendly
monitor is the highly intuitive user
interface for the machine’s Equipment Management and Monitoring
System (EMMS). Multilingual and
with all essential information available at a glance, it features simple
and easy to operate switches and
multifunction keys that provide the
operator with fingertip access to a
wide range of functions and operating information.

Highest Safety Standards
Safe SpaceCab™
Excellent visibility
Specifically designed for Komatsu
excavators, the Dash 8 cab has a
tubular steel frame. It provides very
high shock absorbency, impact
resistance and durability. The seat
belt is designed to keep the operator in the safety zone of the cab
in the event of a roll-over. At your
request, the Komatsu PC800-8 can
also be fitted with an ISO 10262
Level 2 Falling Object Protective
System (FOPS).
The PC800-8’s large capacity cab
and increased glass area provide
superb front visibility. Large mirrors
on both sides ensure that machine visibility meets the latest ISO
standards. Additional work lamps
and a rotating beacon are fitted as
standard, further enhancing safety.
Safe and easy maintenance
Thermal guards are placed around
high temperature parts of the
engine. The fan belt and pulleys
are well protected and in case of
damage, fire risk is reduced by a
pump/engine partition that prevents
hydraulic oil from spraying onto the
engine.
Laminated front screen
The front screen of the PC800-8
is made of laminated glass, for
enhanced protection against chips
produced by rock breaking work.
The single-piece design offers an
uninterrupted view of the working
area.
Safe access
A wide catwalk and large handrails
give safe and easy access to the
cab and to maintenance check
points. Very durable anti-slip plates
– with additional high friction covering – maintain long term traction
performance.

Quality You Can Rely On
Reliable and efficient
Komatsu-quality components
Productivity is the key to success – all major components of the
PC800-8 are designed and manufactured by Komatsu. All essential
functions are perfectly matched
for a highly reliable and productive
machine.
With the latest computer design
techniques and a thorough test programme, Komatsu’s global knowhow produces machines that are
designed, manufactured and tested
to meet your highest standards.
Rugged design
High strength boom and arm
Thanks to the large cross-sectional
structure made with high tensile
strength steel and a thick plate
and partition wall, the boom and
arm provide excellent durability
and are highly resistant to bending
and twisting. Highly durable rubbing strips on the underside of the
arm protect the structure from any
material that might fall from the
bucket.
High pressure in-line filtration
Komatsu strives to minimise the
welding areas on every machine particularly in highly loaded areas.
The swing circle mounting on the
upper structure of the machine and
the undercarriage tower to which
the swing circle is attached are
made from one piece of solid steel,
with no welding. The undercarriage
is strengthened to provide excellent reliability and durability when
working on rocky ground or blasted
rock. Sturdy guards shield the
travel motors and piping against
damage from rocks.
The PC800-8 has the most extensive filtration system available,
providing in-line filters as standard
equipment. An in-line filter in the
outlet port of each main hydraulic
pump reduces failure caused by
contamination.
