High Production and Low Fuel Consumption
Engine
The PC600-7 gets its exceptional power and work capacity
from its Komatsu SA6D140E-3 engine. Output is
287 kW 385 HP providing more hydraulic power.
In addition, the fuel consumption is reduced by 12%
when using Economy Mode.
Large Digging Force
Thanks to the high engine output and an excellent hydraulic
system, this machine demonstrates powerful digging force.
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.
Excellent Swing Performance
Twin-swing motor system of PC600-7 provides excellent
swing performance on slope.
Excellent Machine Stability
Large machine weight and wide track gauge provide
excellent machine stability.
Large Bucket Capacity
Large capacity bucket has large and shallow contour offers
easy loading.

pumps for efficient engine power use. This system also reduces hydraulic
loss during operation.
Active and Economy mode
The PC600-7 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.

Excellent Reliability and Durability
Reinforced Bucket (optional)
PC600-7 bucket is designed exclusively for quarry use
and is higher strength for impact and wear. It is highly
resistant against wear and impact and demonstrates high
performance and reliability. Combined with the saddling
type side shroud and the corner teeth, the life of the buck-
et has been greatly improved.
Strengthened Boom and Arm
(optional)
Thanks to the large cross-sectional
structure employing a high tensile
strength steel with a thick plate, parti-
tion wall, etc., the boom and arm
exhibit excellent durability and are
highly resistant to bends and twists.

O-Ring Face Seal
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 vibration.
Frame Structure
The revolving frame and center frame
mount are no welding structure so that
force is transmitted directly to the thick
plate of the frame without passing
through any welding.
High-pressure In-Line Filtration
The PC600-7 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
failures caused by contamination.
Metal Guard Rings
Metal guard rings protect all the
hydraulic cylinders and improve
reliability.
Heat-Resistant Wiring
Heat-resistant wiring is utilized for the
engine electric circuit and other major
component circuits.
Circuit Breaker
With the circuit breaker, the machine
can be easily restarted after repair.

Sturdy Undercarriage
The undercarriage is strengthened to

Easy Maintenance
Komatsu designed the PC600-7 for easy service access.
Wide Catwalk
Wide walkway for maintenance is provided around the engine and hydraulic
components, allowing easy access to
inspection and maintenance points.
Footing Over Engine
Since a step is being installed to a
section above the engine, daily
inspections of the engine and its
neighborhood can be conducted easily. Also, a protection cover is being
adopted to prevent direct touch of
hands to the high temperature sections such as the turbocharger.
Reduced Maintenance Costs

KOMTRAX
The KOMTRAX system monitors
machine condition, operating status,
