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 1 119 kW (1 500 HP) for
handling the big excavation jobs.
• 1 119 kW (1 500 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 : 17.0 m3
• Loading shovel bucket : 15.0 m3
Maximum Excavating Force.
• Backhoe : Arm crowd force (ISO) : 785 kN (80 000 kgf)
(SAE : PCSA) : 765 kN (78 000 kgf)
Bucket digging force (ISO) : 830 kN (84 600 kgf)
(SAE : PCSA) : 760 kN (77 500 kgf)
• Loading shovel : Arm crowding force : 918 kN (93 600 kgf)
Breakout force : 943 kN (96 200 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.

Productivity-Boosting Auto-Leveling Mechanism— One-lever leveling control.
This is another unique Hitachi function developed exclusively for more efficient
leveling operations.
17.0 m3 backhoe bucket is best matched with 140 tonnes class dump trucks.

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
Integral
The center
cast
track frame of
steel
integral cast
steel structure
can avoid stress
concentration, and increase reliability.
High-Mounted Compact Travel Motors
and Optional Travel Motor Guard— Help
to boost durability at rugged work sites.
This design helps protect the travel
motors from damage by rocks.
Rugged Track Links— Shoes include
roller guides for extended service life.
Roller guide
Strategically Positioned Oil Cooler—
Helps keep oil temperatures
This design has proven itself on
Hitachi's popular Giant EX Series. The
roller guides have been added to help
extend service life.
Constant Correct Track Tension—
Nitrogen gas accumulators absorb
abnormal track tension.
The oil cooler is used for optimal
cooling efficiency. It is positioned far
from the engine radiator for even better
cooling potential.
Helps prevent abnormal track tension
from causing damage. Travel is
automatically stopped if accumulator
pressure exceeds a preset level.
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 6.4 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 190 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
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)
* Illustration shows a sample of the
•Setting oil change intervals with alerting
Emergency Switch.
Much more functions are provided to ease maintenance and servicing.
Outside Cameras (Optional)— Enhances operating
safety.
The operator can monitor around the machine, using
four optional cameras 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.

cleaner.
This is one less time-consuming task
during routine maintenance.
Convenient Centralized Filter System—
Designed to make filter inspection and
maintenance easier.
Contamination sensor— Alerts the operator
of excessive contaminants in the oil.
Centralized position means that
inspection and maintenance can be
performed
