The Robust ZAXIS-3G Series. The Dependable Partner on Tough Job Sites

The new ZAXIS-3G series comes with extra rugged and reliable features and uses the time-tested engine and hydraulic equipment. The result is more production with less downtime.

Notes : Machines pictured on this brochure are positioned for the sake of demonstration. Please take proper safety measures, i.e., resting the bucket on the ground when leaving the machine.

184 kW (246 HP)

172 kN (17 600 kgf)*

H/P (High Power) Mode Select the H/P mode to increase engine speed and engine output, especially when more power is needed during arm retracting in deep excavation.

P (Power) Mode Select the P mode for general excavation.

E (Economy) ModeSelect the E mode to save fuel by decreasing engine speed, while maintaing digging force in the P mode.

In Pursuit of Awesome Power and ProductionBy the best matching of powerful digging force and quick loading speed, the ZAXIS 330G yields high production.

Maximum Bucket Digging Force

237 kN (24 200 kgf)*

High-Powered, Fuel-Efficient Engine

With four suction/exhaust valves,

central combustion chamber and large

turbocharger with intercooler, the engine

delivers big power. What’s more, the HIOS

hydraulic system, designed for optimal

hydraulic energy control responding to

engine speed, saves fuel consumption.

Maximum Arm Crowd Force

Big digging power is available for powerful

excavation through the high-powered

engine and HIOS hydraulic system. In

short, the effective use of big engine

output and optimal hydraulic pressure is

made for high production.*At power boost

*At power boost

11.8 min-1 (rpm)Quick Swing Speed

Quick swing speed allows for efficient

loading onto a dump truck.

298 kN (30 400 kgf)Maximum Traction Force

Strong traction force allows for easy

steering in rough terrains and powerful

slope climbing.

Hydraulic Pressure Control

The auto power lift automatically boosts

hydraulic pressure as needed – when

the load exceeds the specified level

during boom raising – to achieve efficient

loading.

What’s more, the arm regenerative

system works when the arm is retracted

during swinging for next excavation, thus

increasing arm retracting speed.

These mechanisms enable efficient

dumping on dump trucks.

Power Mode Selector

The three power modes are selectable

according to job needs for optimum control of

engine speed and hydraulic pressure.

*Flont glass lower guard on photo is optional.

Engine Speed Control

The auto acceleration (A/A) mode can automatically control

engine speed according to control lever stroke to reduce fuel

consumption greatly in light-duty operations, such as grading and

finishing.

Furthermore, in the auto acceleration mode, the auto idle (A/I)

decreases engine speed to save fuel consumption, when waiting

a dump truck to arrive, with the control lever in

neutral.

The undercarriage is strengthened for smooth travel on rugged sites,

enhancing long-term reliability and durability.

Idler bracket reinforcing plate

Increased bracket width

Track link disengagement preventive plate

Strengthened Undercarriage

Robust Construction with High Reliability The front attachment and undercarriage are strengthened for heavy-duty excavation. The time-tested engine helps get the job done on tough job sites.

Isuzu AA-6HK1X Engine

This engine, already mounted on numerous construction

equipment, has proven ruggedness and reliability in tough

operations. The mechanical governor reduces downtime

caused by

contaminants in dusty

environments.

Strengthened X-Beam

The X-beam is strengthened by reshaping

and enlarging the box-section structure

up to 45% (vs. conventional ZAXIS-1).

Top and bottom monolithic plates are

curved for higher strength, reducing the

number of welding points.

Strengthened Upper and Lower Rollers

Upper and lower rollers are increased in

outside diameter, and upper roller bracket

is thickened for higher durability.

New ZAXIS-3G series Conventional

ZAXIS-1

Larger diameter

Thickened

Improved Idler Brackets

Both the idler bracket reinforcing plate

and track link disengagement preventive

plate are thickened to prevent the opening

of the idler bracket and increase the

durability of track links and rollers.

Added Track Guards

Three track guards are added on each

track to prevent track link disengagement

during steering. Track links are thickened

and reshaped for higher durability and

rigidity.

The durability of the front attachment is enhanced, using reliable boom, arm,

flat bottom bucket and HN bushings.

Enhanced Front Attachment Durability

WC Thermal Spraying

At the arm-bucket joint, its bore contact

surfaces are hardened with WC (Tungsten

Carbide) thermal spraying for higher wear

resistance.

HN Bushings

The HN bushings, made of high-tensile

sintered metal (treated by carburized

quenching), can retain more grease for

better lubrication

and higher

durability.

Reinforced Resin Thrust Plates

Provided at front

joints to help

reduce jerking and

noise.

1.40 m3 Flat Bottom Bucket

The flat bottom

bucket is designed

to protect welds

with a wear plate for

smoother grading

and longer service

life.

The comfort-designed cloth-covered seat is fitted with a

headrest and armrests. The seat can be finely reclined and

slid to suit each operator build for comfortable positioning.

This allows long-hour operation with less fatigue.

The monitor panel is positioned for easy reading by the

operator. The coolant temperature gauge and fuel gauge

each have orange-colored needles and dials to let the

operator monitor at a glance.

The LCD display, centered at the panel, indicates an hour

meter and trip meter. With the work mode switch, the

Excavation and Attachment modes can be selected. When

the mode is switched, hydraulic pressure control is also

switched for smooth operation.

The switch panel is also laid out for easy control with high

reliability.

The cab, resting on the silicone-filled rubber cushions,

absorbs shocks and vibration, and reduces in-cab noise.

CRES Cab

The CRES cab (with OPG* top guard

level I) is reinforced with a central rigid

close-section pillar, and reinforcing

members. The rear frame is thickened to

increase strength and rigidity.

The OPG* cab (with OPG* top guard

level II) is optionally available for quarry

sites to protect the operator from falling

objects.

Full-Auto Air Conditioner

A full-auto large-capacity air conditioner

of fresh air introduction type is designed

for automatic control of air flow and

outlets to keep cab temperature at the

preset level.

HITACHI only offers genuine high quality parts. We guarantee that these parts have high performance and long life. We manage around 1 000 000 types of parts all around the world. They are designed and built to be the best match for your HITACHI equipment. HITACHI has a global parts distribution network that makes sure you get what you need as quickly as possible. We have more than 150 dealers worldwide who provide the closest support for your needs.

In most cases, your dealer will have the replacement part that you require. If a dealer does not have a certain part, he can order it from four fully stocked parts depots located across the world. These distribution centres are all connected by an on-line system that gives them access to shared information on stocks, such as the number and type of available parts.

The depots, which in turn are stocked by a parts center in Japan, minimize delivery time and enable you to get your parts as efficiently and quickly as possible.

Our goal is to “keep customer equipment at a maximum performance level”. To fulfil this goal, we have set more than 150 dealers all over the world. They have highly trained technicians, and provide a number of support programs.HITACHI provides a unique extended warranty program called HITACHI Extended Life Program, or HELP.

To minimize downtime during troubleshooting, we developed a PDA based diagnostic system called “Dr.ZX”. To keep our customers’ equipment in top running shape, good service is indispensable. We believe personnel training is the key to providing the best service.

If you would like more information regarding parts and/or service, please ask your nearest HITACHI dealer. Not all programs and/or services are available in every market or region.
