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.

Working Mode Selection
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.
