Komatsu develops and produces all major

components, such as engines, electronics

and hydraulic components, in house. With

this “Komatsu Technology,” and adding cus-

tomer feedback, Komatsu is achieving great

advancements in technology. To achieve

both high levels of productivity and economi-

cal performance, Komatsu has developed the

main components with a total control system.

The result is a new generation of high perfor-

mance and environment friendly excavators.

Komatsu Technology

PRODUCTIVITY, ECOLOGY & ECONOMY

TOTAL VEHICLE CONTROL

Enables operator to set the

Economy mode to two levels

according to working conditions

so that production requirement

is achieved at the lowest fuel

consumption.

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. This engine is U.S. EPA Tier 2

emission certified.

Reduced noise by adoption of an electronically controlled vari-

able speed fan drive, large hybrid fan and low-noise muffl er.

ECO gauge is equipped for en-

vironment friendly energy-saving

operations. Operation in the green

range allows reduction of CO2

emission and fuel consumption.

To prevent unnecessary fuel

consumption, an idling caution

is displayed on the monitor if the

engine idles for 5 minutes or more.

Auto deceleration system is equipped to reduce fuel con-

sumption and operating noise. Also, engine idling speed can

be reduced on the monitor with the auto idling system.

P and E modes established work modes are further improved.

P mode – Power or work priority mode has low fuel con-

sumption, but fast equipment speed and maximum produc-

tion and power are maintained.

E mode – Economy or fuel saving mode further reduces fuel

consumption, but maintains the P mode-like working equip-

ment speed for light duty work.

You can select Power or

Economy modes using a

one-touch button on the

monitor panel depending

on the workload.

Idling Caution

Auto Deceleration and Auto Idling System

Working Modes Selectable

Gives 12% more lifting force when needed for handling rock

or heavy lifting applications.

Heavy Lift Mode

Since the machine has a large drawbar pull and a high steer-

ing force, it demonstrates excellent mobility even when it is

on inclined sites.

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.

Large Drawbar Pull and Steering Force

Two-mode Setting for Boom

The PC2000-8 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.

RELIABILITY & DURABILITY

The boom foot hoses are arranged

under the boom foot to reduce hose

bend during

operation,

extending

hose life and

improving

operator

safety.

breaker, the

machine can

be easily

restarted

after repair.

Circuit Breaker

Removes water from the fuel and im-

proves the reliability of fuel systems.

Water Separator (Optional)

Revolving frame, center frame and

crawler frame are strengthened com-

pletely. The frames endure heavy-duty

work and exhibit excellent durability.

Strengthened

Frame Structure

The hydraulic hose seal method has

been changed from a conventional

taper seal to an O-ring seal. This pro-

vides improved sealing performance

during operation.

O-ring Face Seal

Fuel system reliability is even better

with high effi ciency fuel fi lter.

Fuel Pre-filter

(With water separator)

The PC2000-8 has the most exten sive

fi ltration system available, pro viding in-

line fi lters as standard equipment. An

in-line fi lter in the outlet port of each

main hydraulic pump reduces failures

caused by contamination.

High-pressure

Large capacity triple-roller bearing is

used for the swing circle. The swing

circle endures

heavy-duty

excavating and

loading work, and

exhibits excellent

durability.

Travel motors are shielded by sturdy

guards. They prevent the motors from

being damaged by the thrust of rocks.

Enlarged track rollers, in combination

with the

Heat resistant H-NBR seal and pack-

ing are employed for the hydraulic

equipment and power train com-

ponents. The heat resistant rubber

employed for the hydraulic hose has

extended its life 1.5 - 2 times.

COMFORT

Downward visibility is drastically improved by extending the

front windshield. This facilitates the operator view of machine

footing. New interior arrangement eliminates blind spots in

work equipment side and provides clear and wide range sur-

rounding visibility in combination with wide glass windows.

Excellent Operational Visibility

Large cab designed for exclusive use in mining shovels

provides enough space to relax during operation. The cab

with improved air tightness is pressurized to prevent dust from

entering. Combined with a large capacity twin air conditioner

(A/C) that cools and heats the cab effectively, ample and

comfortable operating environment is realized.

Spacious and Comfortable New Cab Design

The seat with air suspension minimizes and softens vibrations

transmitted to the operator. Depending on the operatorʼs

weight and physique, the cushion can be adjusted and the

seat can slide fore/aft and vertically.

The machine is equipped with 7-inch

large LCD monitor for secure, and

smooth operation. Panel visibility is

signifi cantly improved by the use of the

high-resolution LCD panel. The panel

switch group is easy-to-use, enabling

switch over of engine output and

increase of lifting force during opera-

tion. Furthermore, use of function key

enables the operator to perform multi-

functions with ease. Character display

can be selected among nine languages.

Easy-to-see and Easy-to-use7-inch Large LCD Monitor
