Boosted ProductivityNew hydraulic system HIOS III and new OHC 4-valve diesel engine were developed for ZAXIS-3.These advanced technologies are at work to yield bigger output with higher fuel efficiency.

Efficient Hydraulic Control - HIOS III

More Production, Less Fuel Consumption

Increased Production

A combination of the hydraulic system

(HIOS*III) and new OHC** 4-valve

engine allows the efficient use of

hydraulic pressure to increase speeds

of actuators and boost production with

higher fuel efficiency. The productivity

is increased 10 % in comparison to

previous model ZAXIS-1.*Human & Intelligent Operation System

**OverHead Camshaft

New E-mode

The new E mode, H / P mode and

P mode can be selected to suit job

needs. The new E mode can save fuel

consumption by up to 10 % compared

to the previous P mode, while yielding

similar production.

Increase in Swing Torque and Traction

Force

Swing torque and traction force are

increased significantly.

OHC 4-Valve Engine

The new OHC -valve diesel engine is

developed and built to comply with the

rigorous Emission Regulations enforced

in 2006 in U.S. and EU. This new

engine contributes to environmental

preservation. At the same time it

realizes high durability and low fuel

consumption by adapting the latest

advanced engine technology.

Common Rail Type Fuel Injection

System

Electronic control common rail type fuel

injection system drives an integrated

fuel pump at an ultrahigh pressure

to distribute fuel to each injector per

cylinder through a common rail.

This enables optimum combustion

to generate big horsepower, and

reduce PM* (diesel plume) and fuel

consumption.

Cooled EGR** System

The cooled EGR system lets part

of exhaust gasses mix with intake

air for re-combustion to reduce

oxygen concentration in the air in the

combustion chamber. This design

lowers combustion temperature in the

cylinder, reducing fuel consumption and

NOx while yielding more horsepower.*Particulate Matter

**Exhaust Gas Recirculation

-Swing torque 10% UP

-Traction force 15% UP

Sophisticated Travel Control;

At climbing or steering, when the

machine needs more traction force, the

engine speed automatically increases

which makes the machine faster.

Development Concept of New Engine

ZAXIS-1 adapted HIOS II hydraulic

system that is suitable for fine

controllability by the operators.

Continuously HITACHI developed new

advanced hydraulic technology HIOS III

for ZAXIS-3.

In addition to the fine controllability this

new system increases the efficiency of

hydraulic circuit and increases speed of

actuators.

The Hydraulic Boosting System

In arm roll-in and boom raise operation,

excess pressurized oil is delivered from

boom cylinder rod side to arm cylinder

bottom side to increase flow rate giving

20 % higher arm roll-in speed. Excess

pressurized oil from boom cylinder rod

side is delivered to arm cylinder bottom

side through a regenerative valve

to increase flow rate for productive

operation.

Enhanced Boom Recirculation System

In combined operation of boom lower

and arm, pressurized oil from boom

cylinder bottom side is delivered to

boom cylinder rod side, assisted by

boom weight, for boom lowering. At the

same time, pressure oil from the pump

is delivered to the arm cylinder for arm

movement.

This mechanism allows an increase of

speed in combined operation of 1� %.

The operator's seat of the ZAXIS-3 series gives the operator an excellent view of the jobsite. On the widescreen color LCD monitor the operator can see machine conditions. Ample legroom, short stroke levers and a large seat ensure optimum working conditions for the operator during long hours.

A New Standard in Operator Comfort

The ZAXIS-3 series cab has been

redesigned to meet demands of

customers. From the operator’s seat

the operator has an excellent view of

the jobsite. On the widescreen color

LCD monitor the operator can see

machine conditions and with the rear

view camera (optional), what is behind

the machine. Ample legroom, short

stroke levers and a suspension seat

(optional) with heating ensure optimum

working conditions. The seat features

horizontal, vertical adjustments and

has a backrest contoured for comfort,

with a HITACHI logo.

Wide adjustable armrests and a retractable seat belt are included. Short stroke levers

allow for continuous operation with less fatigue. Three switches on the lever (optional)

can be set to operate attachments other than buckets. The cab is pressurized to keep

out dust. Noise and vibrations are kept to a minimum due to the elastic mounts, filled

with silicone oil, the cab rests on.

Visibility is improved especially for the right downward view. Sliding windows on the

side enable direct communication between operator and other workers. Foot space

has increased and travel pedals have been redesigned for easier operation.

A flat floor allows for easy cleaning. Ergonomic controls and switches, fully automatic

air conditioner and a radio complete the package.

Embedded Information Technology

The ZAXIS-3 series is equipped with a widescreen color LCD monitor with adjustable contrast for day and night shifts. With the monitor the operator can check maintenance intervals, select work modes, monitor fuel consumption, and connect to the rear view camera (optional). A theft deterrent system and multi-language selection is also available.

Multi Function Monitor

Maintenance Support

The color LCD monitor, located in the

cab, indicates coolant temperature,

fuel level, and maintenance data. It also

allows one-touch adjustment of the

attachment. The display can also be

adjusted to day or night shift.

Replacement timing of hydraulic oil

and fuel filters is alerted to the operator

through the LCD monitor according to

the schedule preset by the user each

time when turning the key switch.

The scheduled maintenance can

prevent the failure of the machine.

Attachment Support System

(work mode selector)

When replacing the attachment, oil

flow adjustment can automatically be

done by one touch on the work mode

selection display on the LCD monitor.

Minor adjustments of oil flow is possible

if necessary.

Multi-language Selection

The menu allows selection from 12

languages.

Theft Deterrent System

Rear View Camera (optional)

Fuel Consumption Monitoring

The widescreen color LCD, teamed

up with the rear view camera on the

counterweight, gives the operator

unobstructed rearward viewing.

The rear view camera automatically

works when traveling, and can also be

manually turned on with a select switch

on the monitor.

Fuel consumption per operating hour is

computed, and the result is displayed

on the LCD monitor. This information

suggests refuelling timing, and guides

energy-saving operation and efficient

job management.

The electronic immobiliser requires

the entry of an encryption code to the

multifunctional monitor each time when

starting the engine to prevent theft and

vandalism.

Simplified Maintenance

The ZAXIS-3 series meet customer demands for simplified maintenance. Regular maintenance is the key for keeping equipment in top condition, which can help to prevent costly downtime. In addition, a regularly serviced machine has higher residual value. There are many service features to be found on the ZAXIS-3 series.

Parallel Arrangement of the Cooling Pack

Conveniently Located Servicing Points

Extended Oil and Filter Change Intervals

The fresh air filter for the air conditioner

is relocated to cab door side from

conventional location behind the

operator seat. This allows easy cleaning

and replacement of the fresh air filter,

like the air circulation filter inside the

cab.

Wide doors give access, from ground level, to the fuel filter, water separator and

engine oil filter. A large handrail, steps and anti-skid plates lead to the engine cover.

The engine oil pan is fitted with a drain coupler. When draining, an associated drain

hose is connected to the drain coupler. The drain coupler is reliable, avoiding oil

leakage and vandalism.

The oil cooler, radiator and intercooler are laid out in a parallel arrangement, instead

of the conventional in-line arrangement. This parallel arrangement is significantly

easier to clean around the engine. The air conditioner condenser can be opened for

easy cleaning of the condenser and the radiator located behind.

The oil and filter change intervals have

been extended considerably, reducing

maintenance time and expenses.

Engine oil consumption is lower.

Hydraulic oil can be used up to � 000

hours.
