More Production with Less Fuel |
 |
|
5% Reduction in Fuel Consumption
New ZAXIS is a fuel-thrifty excavator that can reduce fuel consumption by 5%*, compared to the conventional ZX330-3/ZX330-3F family, thanks to the HIOS III hydraulic system and engine control system, thereby reducing CO2 emissions.
*3%, compared to the ZX330/ZX330-3G
More Fuel Reduction in the ECO mode
The ECO mode, a new economical mode, can further cut fuel consumption by 9% compared to the PWR mode, without sacrifcing digging speed by optimal matching of operations. |
 |
| Swift Front Movements with HIOS* III Hydraulics
Operating speed increases with less fuel consumption thanks to the HIOS III hydraulic system, developed by industry-leading hydraulic technologies and a wealth of experience. Actuators work quickly by boom weight, without needing a regenerative circuit and pressure oil.
*Human & Intelligent Operation System Rapid Arm Roll-in
Arm roll-in speed increases by combined flow from arm and boom cylinders through regenerative valves for productive excavation Fast Arm Speed During Boom Lowering
Arm speed increases by boom weight during boom lowering, without needing pressure oil from a pump. That is, arm circuit flow is increased for higher arm speed, allowing for quick loading of a dump truck and positioning of the front |
| Powerful Lifting Operation
The Auto Power Lift mode, which automatically surge lifting force by 10% when needed, allows for powerful lifting of buried concrete pipes or sheathing sheets. Enhanced Power Boost
The Power Boost mode allows the operator to surge 10% more digging force for powerful excavation by pressing its button on the control lever. |
Pursuits of Performance and Durability |
 |
| Prestige R&D and Quality Control
Hitachi has earned praise for technological prowess and product performance around the world. R&D Division has a track record – including excellent design, stress analysis expertise using CAE system, and abundant production data base. What’s more, a large-scale durability test field (427 hm2) allows for a series of stringent testing of new machines. Production Division strives to automatize production processes, including robotic welding, machining, painting, assembling and transferring. |
 |
| Durable, Reliable Engine
This engine has a track record showing impressive durability at countless tough job sites around the world. The engine - associated with a rugged design, a direct fuel injection system and an elaborate governor goes green, and complies with EU Stage II and US EPA Tier 2 emissions regulations. The cooling system well keeps the engine cool.
The cooling fan is improved to cool the engine more efficiently.
The ample-capacity intercooler and turbocharger help yield a whopping 184 kW (246 HP) output for higher production in shorter job schedule |
| Rock-Solid, Durable Front Attachment
The boom top and boom foot brackets frame side are reinforced with thickened high-tensile steel, which incorporate steel bushings to enhance durability. Arm cylinder and boom cylinders (rod extend ends) cushion shocks at stroke ends to cut noise and extend service life.
Joint pins at the front attachment are tightly fit to reduce jolt and sound. The arm-bucket joint is protected by WC thermal spraying on its contact surfaces to reduce wear and jolt. New-type HN bushings, utilized on joint pins, retain grease inside for longer greasing intervals. A reinforced resin thrust plate, provided at front attachment joints, helps reduce wearing noise |
 |
| Strengthened Undercarriage
The X-beam frame is made monolithically with fewer welds for higher rigidity and durability. Track adjusters absorb impacts to crawlers. Front idlers and adjuster cylinders are integrated to increase durability. Idler brackets and travel motor brackets are both thickened for added durability Proven Upperstructure
The upperstructure frame is reinforced with the proven D-section skirt to increase rigidity against damage by obstacles. The door catch is improved to shut the door tightly, reducing door rattling. |
No Compromise on Operator Comfort |
 |
 |
| Comfortable Operating Environment
You'll feel comfortable and confident, with plenty of leg space and excellent visibility when entering the cab. The new compact console gives more leg space. The new door pillar is shifted rearward by 70 mm to widen an entry space for easy access. A new LED room light, interlocked with the door, turns on when the door opens. The front window is easily removed and stored overhead using slide rails. The overhead window is openable for ventilation. Lots more air vents for air conditioner are located strategically for uniform air circulation inside the cab. The control panel and control levers are arranged within easy reach of the operator. AM/FM radio and AUX port (optional) for a mobile music player are available for a long work day with less fatigue. All these designs focus on operator comfort. Comfort-Designed Operator Seat
The luxury cloth seat is fitted with a headrest and arm rests for operator comfort. The seat can be adjusted in multiple ways, sliding and reclining, to suit operator’s size and preferences. The seat can slide rearward by 40 mm more for added leg space. The air suspension seat with a heat pad is optional. Robust Cab
The robust cab, meeting the OPG (Top Guard Level 1), protects the operator from falling objects. The pilot control shut-off lever is provided with a neutral engine start system that permits engine starting only when the pilot control shut-off lever is in Lock position. |
 |
| New, Easy-to-Use Multifunction Monitor
The new multi-language, multifunction monitoring system comprises a 7-inch highresolution color monitor and a multifunction controller. The monitor allows the operator to check varying operating variables: coolant temperature, fuel level, work mode, full-auto air conditioner, AM/FM radio, rear view monitor camera (optional), maintenance support, and attachment flow adjustment. Menu items can be selected and adjusted by a multifunction controller on the control panel. A new rear view monitor camera always displays the view behind the machine |
Simplified Maintenance |
 |
| Dust-Proof Net
A dust-proof net, provided at the front of radiator, can be easily removed and cleaned with compressed air. Grouped Remote Inspection Points
Service points are concentrated inside left and right covers that are readily accessible from ground level for convenient servicing and inspection, including water draining from the fuel tank, replenishment of coolant, and replacement of filters. The fuel tank is anti-corrosion coated on its inside, and has a large cleaning port at the bottom. These wise designs effectively keep fuel clean, and ease servicing. Handrails are provided at convenient locations for easy riding on the upperstructure. Plenty slip-resistant plates are located for safe maintenance. |
| Attractive, Robust Body
Side frame tops of the undercarriage are sloped to let muck slide away. Track adjuster greasing ports are repositioned for easier lubrication, and well protected from muck packing |
 |
| Low Life Cycle Costs
Service intervals are long enough to slash maintenance costs |
Reliable Solutions, with Various Options |
 |
 |
|
Easy-to-Use Attachments
The operator can change over valves, adjust extra circuit flow, and check settings from the multifunctional monitor next to the operator seat. What’s more, 11 jobs, including flow rate setting, can easily be selected by their identified names.
Easy-to-Operate Breaker
When using a breaker that requires frequent change of hydraulic oil and filters, an extra hour meter on the multifunctional monitor displays operating hours of the breaker, suggesting adequate replacement timing of oil and filters. The Breaker Alarm (optional) displays an alert mark on the monitor screen, and sounds when the breaker works continuously over one minute.
Varied Jobs, Varied Options
Lower cab front guard is provided for protection against debris during demolition and breaker operation. High-performance filters are available and are recommended for using breaker frequently. |
