Easy Maintenance
● Replacement interval is extended for
engine oil, engine oil filter and
hydraulic filter.
● Easy removal and installation of the
radiator and oil cooler
● Fuel tank capacity is increased.
● New bushing design on work
equipment extend lubricating interval.
● Easy access for engine inspection
● High-capacity air cleaner
See pages 8 and 9
Harmony with Environment
● Low emission engine
Powerful turbocharged and aftercooled Komatsu SAA6D125E-3 engine
provides 246 kW 330 HP.
● Economy mode saves fuel consumption (reduced by approx. 20%).
● Low operation noise
● Designed for optimal use of recyclable materials
Large Comfortable Cab
New PC450-7’s cab volume is increased by 14%,
offering an exceptionally roomy operating environment
● Highly pressurized cab with optional air conditioner
● Low noise design
● Low vibration with cab damper mounting
● OPG capable with optional bolt-on top guard
OPG (Operator Protective Guards) top guard level 2 by ISO 10262 (formerly FOG)
See page 6 and 7
● High Production and
Low Fuel Consumption
Production is increased during Active
mode while fuel efficiency is improved.
● Low Fuel Consumption and High
Output Engine
A powerful turbocharged and air to air
aftercooled Komatsu SAA6D125E provides
246 kW 330 HP.
Low fuel consumption is achieved by
adopting an electronic controlled fuel
injection system.
● Large Digging Force
Arm crowd force is increased 8% and
bucket digging force is increased 10%
when the Power Max function is applied.
(compared with PC450-6).
● Two-mode Setting for Boom
Switch selection allows either powerful
digging or smooth boom operation.

● Excellent Machine Stability
Machine stability and balance is improved by a
new design counterweight.
● Higher Lifting Capacity
PC450-7’s lateral stability is improved and lifting
capacity is increased.
See page 5
Reduced revolving frame damage
● Clearance between the revolving frame and
track increased by 30%.
See page 5
Improved lateral stability is achieved by increasing the
counterweight (330kg 730lb) and improving the balance of
the machine body.

Large Lifting Capacity
PC450-7’s improved lateral stability increases lifting capacity.
Variable Track Gauge (optional)
● Lateral stability is significantly improved when
operating with the gauge extended.
● Lateral stability is increased by 30% (compared with
the fixed gauge of the current model).
● Complies with transportation regulations by retracting
the gauge.

High production and low fuel consumption are
achieved through the following two operation
modes:
Active mode, with maximum engine output to handle large
production, while keeping fuel consumption low; and Eco
mode for light duty applications, which enables operation
at a speed comparable to Active mode with even lower fuel
consumption. The two modes, Active mode for handling
“large production” and Eco mode for “low fuel consumption”
have been significantly improved.
ACTIVE MODE
This mode handles large production by providing powerful
and speedy operation, and achieves economical efficiency by
substantial reduction of fuel consumption.
ECONOMY MODE
Operation speed equal to that of the Active mode can be
achieved when handling light duty operation while also
keeping fuel consumption low.
Electronically Controlled High Power Engine Installed
A 246kW (330HP) Komatsu SAA6D125E engine, is the
largest in its class.
High power and low fuel consumption are achieved by
optimizing fuel injection via electronic control.
Maximum Digging Force among the 40-ton Class
With the addition of a one-touch power max. function
(operation time of 8.5 seconds), the digging force has been
further increased.
Maximum arm crowd force (ISO):
217 kN (22.1t) 233 kN (23.8t)
Maximum bucket digging force (ISO):
253 kN (25.8t) 278 kN (28.3t)

Substantially Improved
Stability
Smooth Loading Operation
Two return hoses improve hydraulic
performance. In the arm out
function, a portion of the oil is
efficiently returned to the tank .
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.
