Smooth Loading Operation

Two return hoses improve

hydraulic performance. In the arm

out function, a portion of the oil is

returned directly to the tank

providing smooth operation.

Boom floats upward, reducing
lifting of machine front. This
facilitates gathering blasted rock
and scraping down operations.

Boom pushing force is
increased, ditch digging and
box digging operation on hard
ground are improved.

Two-mode Setting for Boom

Smooth mode provides easy operation for gathering blasted

rock or scraping down operation. When maximum digging

force is needed, switch to Power mode for more effective

excavating.

PRODUCTIVITY & ECOLOGY FEATURES

HYDRAULIC EXCAVATOR

Environment-friendly Clean Engine

The PC300-8 gets its exceptional power and work capacity

from a Komatsu SAA6D114E-3 engine. Output is 184 kW

246 HP, providing increased hydraulic power and improved

fuel efficiency.

Komatsu SAA6D114E-3 engine meets EPA Tier 3 and EU

Stage 3A emissions certified and reduced NOx emission by

40%.

The SAA6D114E-3 engine adopts the electronically con-

trolled Heavy Duty HPCR* fuel injection system.

*HPCR : High Pressure Common Rail

Hydraulics

Unique two-pump system ensures smooth compound

movement of the work equipment. HydrauMind controls

both pumps for efficient engine power use. This system

also reduces hydraulic loss during operation.

Low Operation Noise

Enables a low noise operation using the low-noise engine

and methods to cut noise at source. Ambient noise meets

the EU Stage 2 noise regulation.

Komatsu Technology

Komatsu develops and produces all major

components, such as engines, electronics

and hydraulic components, in house.

With this “Komatsu Technology,” and adding

customer feedback, Komatsu is achieving

great advancements in technology.

To achieve both high levels of productivity

and economical performance, Komatsu has

developed the main components with a total

control system. The result is a new genera-

tion of high performance and environment

friendly excavators.

Return hoses

Large Digging Force

With the one-touch Power Max. function digging force has

been further increased. (8.5 seconds of operation)

Maximum arm crowd force (ISO):

160 kN (16.3t) 171 kN (17.4t)

(with Power Max.)

Maximum bucket digging force (ISO):

212 kN (21.6t) 227 kN (23.1t)

(with Power Max.)

Working Modes Selectable

Two established work modes are further improved.

P mode – Power or

work priority mode has

low fuel consumption,

but fast equipment

speed and maximum

production and power

are maintained.

E mode – Economy or

fuel priority mode

further reduces fuel

consumption, but

maintains the P-mode-like working equipment speed for light

duty work.

You can select Power or Economy modes using a one-touch

operation on the monitor panel depending on workloads.

Idling Caution

To prevent unnecessary

fuel consumption, an idling

caution is displayed on the

monitor, if the engine idles

for 5 minutes or more.

Eco-gauge that Assists Energy-saving Operations
