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.
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.

Easy Maintenance
Komatsu designed the PC600-7 for easy service access.
Wide Catwalk
Wide walkway for maintenance is pro-
vided 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 easi-
ly. Also, a protection cover is being
adopted to prevent direct touch of
hands to the high temperature sec-
tions such as the turbocharger.
Reduced Maintenance Costs
Hydraulic oil filter
replacement is extended
from 500 to 1000 hours.

DT-type connectors seal tight and
have higher reliability.
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.

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.
Motorized Grease Gun Equipped
with Hose Reel (optional)
Greasing is made easy with the electric
motorized grease gun and indicator.

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.
Photo may include optional equipment.
KOMTRAX
®
System (optional)
The KOMTRAX system monitors
machine condition, operating status,
operating location, etc., and provides
timely notification of any machine prob-
lems.
Since data is transmitted via satellite
communication system, secure data
communication is possible from any
operating site including a quarry or a
mine, further improving machine relia-
bility.
(There are some countries where
this feature is not in service.
Please consult Komatsu dis-
tributor for availability.)
Sturdy Undercarriage
The undercarriage is strengthened to
provide excellent reliability and durabil-
ity when working on rocky ground or
blasted rock.
