INTRODUCTION OF HITACHI WHEEL LOADER

When you sit inside the cab of a ZW wheel loader, you’ll see that it offers exceptional all-round visibility. Switch on the engine and you’ll hear that it’s the quietest machine on the market. When you start work, you’ll feel the benefit of the comfortable seat, easy-to-use controls and smooth operation.

We know our compact, medium and large wheel loaders not only appeal to your senses, but also make sense for your business. With substantial loading capacity, powerful digging force and impressive travel speeds, they’re extremely productive. Fuel-efficient and easy to maintain, they offer reduced running costs. Used with a variety of attachments, they are easily adaptable for different tasks.

We understands very well the types of construction machinery and equipment suitable to the construction, financial and operational conditions of Vietnamese contractors. We currently supply all kinds of Hitachi equipment such as Mini excavators (with a working load of 800kg) to large mines (up to 533 tons largest), wheel loaders, Ben runs in the mine with a load of 180t or more.

HIGHLIGHTS

A 10% Fuel Saving

The “Active Engine Control System” can reduce fuel consumption by 10%, while enhancing controllability and productivity

Technology to Cut Fuel Consumption

Here are some fuel-saving techniques: avoiding rapid start of travel, and eliminating energy losses during excavation through variable displacement hydraulic pumps.

10% * FUEL SAVING = ACTIVE ENGINE CONTROL SYSTEM + QUICK POWER SWITCH (QPS) NEW TRANSMISSION

* Compared to the conventional ZW180

Active Engine Control System for Economical Operation and Easy Control

The “Active Engine Control System” plays a key role achieving a 10% fuel saving. Strategically positioned sensors detect movements throughout the machine and adjust engine speed accordingly to eliminate energy losses to maximize fuel conservation. This delivers smooth, fuel-efficient operation.

Active Engine Control System for Digging

- Active engine control - Choosing optimal traction power and breakout force

• Increased operating efficiency + Reduced fuel consumption

- Conventional + Excessive traction power by too much pedal depression

• Reduced operating efficiency + Increased fuel consumption

The Active Engine Control System chooses optimal traction power and breakout force for smooth digging while improving fuel efficiency, utilizing data collected from the sensors on the machine.

2 Selectable Work Modes: Standard and Power Modes

Standard mode is preselected and enough for ordinary work that requires constant power, such as loading. Power mode is selectable when extra power is needed.

Power Mode : Select this mode when extra power is needed, such as climbing a steep slope or getting the job done quickly. 

Quick Power Switch (QPS) Pressing the Quick Power Switch on the lever selects the Power mode. When switching forward/reverse, or when a reduction in traction is detected, the Standard mode resumes automatically. The Quick Power Switch helps save more fuel compared to operation when the Power mode is constantly selected.

ECO Mark Indicator for Fuel-Efficient Operation

Monitor indication items: Clock, oil replacement intervals, travel speed, mileage, hour meter

The ECO mark indicator turns on when fuel-efficient operation is activated. This function encourages operators to utilize fuelefficient operation.

Enhanced Controllability

Hitachi analyzed various wheel loader operations including digging, approach to a dump truck, operation after dumping and travel. This led to the development of strategies to improve wheel loader controllability

New Transmission with 5 speed gears

The new transmission comes standard with the Auto mode* that can automatically select an optimum gear according to the load, thereby reducing fuel consumption. Especially, the new transmission has 5 speed gears which can keep fuel efficient engine rpm more easily compared to the conventional transmission with 4 speed gears. 

* AUTO1 (1st-5th gear) and AUTO2 (2nd-5th gear) are selectable using travel mode selector.

Levers for Easy Operation

In order to offer more efficient and comfortable operation, a new type of lever is employed to suit both fingertip control and grip control.

* A variety of lever patterns are available depending on job needs and operator’s preference.

Speed-responding Clutch Cut-off System

Clutch cut-off timing is adjusted by sensing travel speed and pedal depression for smooth, efficient truck loading. The Flat mode, Slope mode and OFF are selectable by switch control according to job requirements

Delay Mode (Optional)

Shift change delay mode is provided to avoid an excessive rise in travel speed during digging and loading. When moving forward with the lift arm up, the second gear is kept for four seconds to prevent over-speed. When reversing, the second gear is kept for five seconds. These delays to third gear help to keep fuel consumption down ensuring smooth loading.

Lift Arm restriction valve

This restriction valve suppresses the shaking of the machine when the lift arm stops to improve operator comfort and avoid load spills.

Lift Arm Auto Leveler (Optional)

The lift arm can be automatically stopped at an preset level for efficient truck-loading, and lowering the bucket after dumping. The operator can concentrate on traveling without worrying about the lift arm.

Operator-Friendly Features to Improve Operator Comfort

The cab is both comfortable and functional with a series of features aimed at reducing operator fatigue.

Bi-Level Auto Air Conditioner

This auto air conditioner has bi-level control function: warming at foot space and cooling at overhead. The pressurized cab shuts out dust, keeping the cab interior clean. In dusty environments, optional external double-filters are available for the air conditioner.

Panoramic Cab

The spacious panoramic cab offers near all-round visibility through pillar-less bonded windows. The seat and steering wheel can be adjusted to suit the operator, keeping the operator in an optimum position. In-cab noise is suppressed further. Even when the going gets tough, the operator can feel comfortable

Tiltable Steering Wheel

The steering wheel is tiltable to fit the wheel to the operator for comfortable operation.

Comfort-Designed Suspension Seat

The mechanical suspension seat absorbs shocks and vibration from the machine in order to reduce operator’s physical stresses to the operator. 

* The air suspension seat is available as an option.

AM/FM Radio with 2 Speakers

The AM/FM radio has an autotuning feature and the 2 speakers stereo system provides excellent sound quality. The player pocket can hold a cell phone. 

* An AUX port (stereo mini jack) is an option for connection with a mobile music player for entertainment during breaks.

Rearview Monitor (Optional)

The rearview monitor allows the operator to see the rear of the machine, including a view behind the counterweight. This rearview monitor enhances safe operation.

An Array of Convenient Accessories

Simplified Maintenance with Proven Support System

Hitachi Support Chain offers a comprehensive suite of support services for customers.

Robust Frame

The main frame and its joins are thoroughly strengthened. The boxsection structure is adopted around center pins, where concentrated forces are applied, for reinforcement. Frame plate thicknesses are optimally determined by 3D stress analysis.

Wide Fin Pitch Radiator (Optional)

Wide fin pitch radiator is available for use in dusty environments, where there are large amounts of airborne debris, to avoid dust clogging and overheating as a result. Air blowing is easy and simple.

Automatic Reversible Cooling Fan (Optional) to Reduce Dust Deposits

The automatic reversible cooling fan is available to keep the radiator clean at all times. The cooling fan is automatically selfreversed every 30 minutes to blow dust off the radiator. The cover swings up for efficient air blowing.
