Hitachi Launch New Range of Wheeled Excavators

Close Move

The new generation of Hitachi Zaxis-3 wheeled excavators has arrived in Europe. The ZX140W-3, ZX170W-3, ZX190W-3 and ZX210W-3 will be unveiled to the public for the first time at Bauma 2007.

The models have been developed by Hitachi to further strengthen its range of construction equipment. They complement the line-up of Zaxis-3 crawler excavators and the other Hitachi machines, which continue to meet the demands of the industry in key areas such as versatility and productivity.

The new Hitachi Zaxis-3 wheeled excavators have been attributed with the same advanced technological features as the crawler equivalents that were launched at Intermat 12 months ago. They also have a number of other innovative features that will help provide better performance, ultimate comfort and safety and reduced running costs.

Better performance

Hitachi has equipped the Zaxis-3 wheeled excavators with powerful, new durable engines, which provide operators with better digging capabilities and faster travel speed. These are further enhanced by a wider oscillation angle of up to 16%, which increases the level of stability and grip on the surface.

Features	Benefits
Hydraulic system (HIOS III) DOHC four-valve diesele ngine New e-mode Innovative hydraulics Revised circulation system Hydraulic boosting system Increased swing torque and traction forces Wider oscillation angle	Increased productivity Reduced fuel consumption Compliance with European stage III emission regulations Greater control over arm and boom Increased operating speed Increased arm roll-in speed Faster travel speeds Improved grip and stability

Ultimate comfort and safety

Hitachi has designed the new Zaxis-3 wheeled excavator models with operator comfort in mind. As well as having spacious and comfortable cabs, each machine has been fitted with Bridgestone tyres, which have an improved tread pattern. This helps to reduce vibration and noise levels.

Features	Benefits
Fully adjustable, heated seat interior Ample leg room and foot space Short-stroke levers Enlarged window surface Theft deterrent device Rear-view camera Dashboard with LCD monitor Strong cab structure Silicone oil-filled elastic cab mounts	Comfortable and variable working conditions Continuous operation with less fatigue Excellent all-round visibility Requirement of pin-code to start machine Enhanced feeling of control and safety Work mode selection function Facility to check maintenance intervals and fuel consumption Improved resistance to impact Reduced noise and vibration

Reduced running costs

Running and maintenance costs for the Hitachi Zaxis-3 wheeled excavators have been reduced in comparison with their predecessors. This is due to the combination of a new engine and hydraulic system, integrated back wheel axle, easily accessible inspection points and more durable components.

Features	Benefits
All major inspection points within easy reach More durable undercarriage Firmer chassis Stronger front attachment New hydraulic system Onboard satellite system Structured power train	Convenient for servicing from ground level Allows easy cleaning of components Enhanced stability Increased residual value Ultimate reliability Extended oil and filter change intervals Reduced maintenance time and costs Facility to check engine condition, technical faults and location Reduced downtime Integrated transmission and back wheel axle Reduced fuel consumption
