Hitachi Zaxis excavator series spotlight

Ask any experienced Aussie operator what separates a good excavator from a great one, and the conversation almost always turns to thehydraulics, which can make or break a machine.

On civil projects across the country, where deadlines are tight and conditions are unpredictable, machine feel and control are everything and only a handful of brands really nail both. One is Hitachi, with its famed Z series excavators.

The brand’s bright orange machines have carved out a strong following in local earthmoving circles, making them a common sight on Australian infrastructure projects, at quarries and even mine sites.

At the core of Hitachi’s local success is the versatile Zaxis lineup, which offers everything from nimble mini diggers right through to medium-sized production models, all built around a proven mix of operator refinement, mechanical durability, and minimal downtime.

Let’s take a look at how the Zaxis nameplate earned its place as a favourite in Australian construction, but first, a little more about the brand behind the machines…

The engineering in today’s Zaxis range extends all the way back to 1910, when Hitachi was founded in Japan; initially as a repair shop for a mining plant.

When the company manufactured its first cable-operated shovel, the U05, back in 1949, its excavator journey began. A couple of decades later, in 1969, Hitachi launched the UH03M, which was Japan’s first fully hydraulic excavator.

The Hitachi brand arrived in Australia by the ‘70s, but largely in the form of its trains. It wasn’t until 1999 that Hitachi Construction Machinery Australia (HCA) was established, providing local contractors with the brand’s mining and construction equipment.

A year later Hitachi debuted the Zaxis nameplate globally, replacing older generations witha new generation of excavators that offered smoother compound movements and reduced fuel burn.

Soon after, in 2001, the release of the Zaxis U short-tail swing series redefined compact earthmoving, laying the groundwork for more than two decades of strong market performance in Australia.

Most operators who have spent time in a Hitachi excavator will agree they’re smooth to operate, which is the result of smart hydraulics, but they’re also powerful, comfortable and offer great fuel economy.

Rather than relying on standard hydraulic setups that can suffer from power loss or jerky movement when you’re running multiple functions at once, Hitachi engineers developed systems like the advanced HIOS V and multi-pump TRIAS III hydraulics found in medium and large Zaxis models.

By utilising a multi-pump architecture to direct hydraulic oil flow precisely where it’s needed without throttling engine power, operators experiencesmooth controlacross boom, arm, and swing movements.

This hydraulic efficiency also reduces diesel consumption,helping operators reduce fuel use and overall fleet emissions.

Diversity across tonnage classes is a major reason the Zaxis nameplate is so prevalent on Australian jobsites, offering a machine for just about every use case.

For tight residential jobs, urban utility work, and roadside maintenance, compact short-tail swingers like the ZX75US-7 and swing-boom ZX85USB-7 allow operators to swing freely in tight conditions.

Moving up into general civil construction, 13-to-14-tonne contenders like the ZX130-7 and ZX135US-7 have earned a loyal following among contractors who need a machine that’s easy to move on a standard float while still packing serious breakout force and lifting capacity.

Further up the scale, medium-class workhorses like the ZX210LC-7 and heavy-hitting ZX360LC-7 tackle work like bulk site cuts, rock ripping, and quarry loading, combining heavy-duty undercarriages with clean-burning, fuel-efficient engines capable of handling tough Aussie conditions.

The release of the latest Zaxis-7 series takes operator comfort, site safety, and machine management to a new level for the brand, spanning its compact, mini and medium model options.

Hitachi’s latest Zaxis-7 machines are built around a redesigned cab offering an improved driver fit, complete with ergonomic joysticks, reduced noise levels, and an eight-inch LCD display that stores custom hydraulic flow settings for up to 12 work tools.

Jobsite smarts and safety also get an upgrade, with features like the Aerial Angle camera system, giving operators a 270-degree bird’s-eye perspective around the machine on screen, and LED work lights that stay on after engine shutdown so operators don’t have to climb down in the dark.

Down below, reinforced boom and arm structures minimise pin play, while an integrated ConSite telematics system monitors machine healthin real timeusing automated oil monitoring sensors to alert owners to potential maintenance needs before they turn into costly downtime.

The latest Zaxis lineup offers a well-rounded range of excavators, but Hitachi hasn’t reinvented the wheel so they remain familiar for operators who are used to the earlier Z series models.

More than 25 years since the Zaxis nameplate first arrived, Hitachi’s commitment to building comfortable, operator-focused machinery remains,helping make them a staple on jobsites around the country.

Combining intuitive hydraulic feel, long-term durability, and strong second-hand value, Hitachi’s Zaxis series excavators area proven choice for operators looking for a premium machine.
