Giant-Sized Productivity
Based on Hitachi's
Theory of Evolution.
Each Hitachi generation listens
to the needs of the work site
and gives birth to an even-better
new generation.
Powerful Single Engine— Ready for the task.
Time-proven Cummins diesel engine produces a total of 810 kW (1 086 HP)
for handling the big excavation jobs.
• 810 kW (1 086 HP)
Emission Control Engine— Helping to protect our environment.
Conforms to U.S. EPA Tier Ⅱ emission regulations.
Efficient E-P Control— Adjusts power output to the work being performed.
Hitachi's computer-aided Engine-Pump Control (E-P Control) coaxes
optimum efficiency from the engine and hydraulic pumps. This innovative
system senses load demand and controls engine and pump output for
maximum operating efficiency.
Larger Bucket Provides High Work Capacity.
• Backhoe bucket : 12.0 m3
• Loading shovel bucket : 11.0 m3
Maximum Excavating Force.
• Backhoe : Arm crowd force (ISO) : 620 kN (63 200 kgf)
(SAE : PCSA) : 609 kN (62 100 kgf)
Bucket digging force (ISO) : 671 kN (68 400 kgf)
(SAE : PCSA) : 617 kN (62 900 kgf)
• Loading shovel : Arm crowding force : 710 kN (72 400 kgf)
Breakout force : 660 kN (67 300 kgf)
Large Bucket— Designed to enhance efficiency.
The large bucket has been shaped specifically to enhance scooping
and loading operations. Its sharp
tilt angle helps boost operating
efficiency.

More Than Durable
Just Plain Tough
Built-in toughness means the
Hitachi will continue to get
giant-sized jobs done fast.
Rigid Box Design— Resists bending
and twisting forces.
Computer-assisted analysis was
used to check that the frame box can
withstand heavy-duty excavation work.
Center Track Frame
Strategically Positioned Oil Coolers—
Helps keep oil temperatures
An oil coolers is used for optimal
cooling efficiency. They are positioned
far from the engine radiator for even
better cooling potential.
High-Mounted Compact Travel Motors
and Optional Travel Motor Guard— Help
to boost durability at rugged work sites.
Integral

steel
The center
track frame of
integral cast
steel structure
can avoid stress
concentration and increase reliability.

This design helps protect the travel
motors from damage by rocks.

Constant-Cab-Comfort Air Conditioner— Keeps the cab pressurized to keep out dust
while maintaining comfortable temperature.
Intelligent Multi-Display Monitor provides machine data
and operating status at a glance.
The operator can monitor machine conditions and
operating status with a 10.5-inch color LCD. The
controller provides instant fault diagnosis through all
sensors, displaying warnings and countermeasures if
failure arises.
Major Functions:

SOLUTION
GIANT
Designed to Offer Comfort
and Intelligence
Comfortable operator space
and simplified maintenance,
backed by Hitachi technologies
and experience.
High Visibility 6.03 Meter Cab Height—
Providing a clear view of the work area.
Rugged Comfortable Cab— Protects
the operator from falling objects.
Efficient Cab Layout— All controls
within natural reach of operator.
Gives the operator a clear view, even
when a large 90 tonnes class dump
truck is being loaded. This high height
and forward-sloping cab provides a
view that boosts productivity.
Fluid filled elastic mounts help absorb
vibration to provide durability and
a comfortable ride. The OPG* top
guard level II (ISO) is provided on the
cab roof.
The ergonomic layout of the cab means
the operator will do less stretching and
reaching when operating the controls.
This adds up to less operator fatigue
and greater operating efficiency.
*Operator Protective Guard
8
Electric Joystick Levers— Provides
pleasant control with less fatigue.
Electric joystick control levers have a
feather-touch allowing long periods of
effortless operation. Its stroke is much
shorter than that of hydraulic control.
Air Suspension Seat with Auto Operator
Weight Adjuster.
The operator seat cushion can
automatically be adjusted according to
the operator weight. This is convenient
for a machine operated by two or more
operators.
•Multiple meters, and alert symbols indication
•Alert/failure status, and countermeasures indication
•Snap-shot function that stores operating data, including
fiveminute operating data immediately before alerting, and
succeeding one-minute data (temperatures, pressures,
and more)
•Setting oil change intervals with alerting
Much more functions are provided to ease
maintenance and servicing.
* Illustration shows a sample of the
Emergency Switch.
Outside Cameras (Option)— Enhances operating safety.
The operator can monitor around the machine, using
four cameras (option) to eliminate blind spots.
Adjustable Sliding Cockpit— Moves to
the best position for the operator.
The operator can adjust the position of
the levers and the seat to custom fit his
size and operating style.

Designed to be
Maintenable
Counterweight with Walkway— Easier
access for maintenance.
Auto Lubrication System Eliminates the
need for manual lubrication.
The Centralized Lubrication System:
Fast Filling System
This system automatically lubricates the
front joint pins and swing circle. This
eliminates cumbersome daily lubrication.
Carefully engineered to allow
full 24-hour operation.
Easy-to-Replace Grease Drum Can—
Designed to provide quick and easy
grease drum can
changes.
A walkway around the entire counterweight provides easy access to key
rear areas. This means faster and safer
inspection and maintenance.
Folding Stairs with Wide Steps (Option).
Low Maintenance Dust Ejector—
Automatically expels dust from the air
cleaner.
The compartment
floor slides down
to lower a drum
for simple, easy
replacement.
This is one less time-consuming task
during routine maintenance.
Contamination sensor— Alerts the operator of excessive contaminants in the oil.
Convenient Centralized Filter System—
Designed to make filter inspection and
maintenance easier.
This system detects accumulated
contaminants that could cause damage
and alerts the
operator before
trouble occurs.
Centralized position means that
inspection and
maintenance can
be performed
quickly and easily.
Folding stairs is designed for easy access to the machine for servicing and
maintenance.
Wide-Open Service Area— Provides the
space needed for quick and easy inspection and maintenance.
Easy Access and Maintenance—
Easy access speeds inspections and maintenance.
