The Hitachi EX1200-6 excavator is a revolutionary hydraulic excavator, which takes advantage of the latest developments in heavy machinery technology. The EX1200-6 is designed and built to handle major applications, such as mines and civil engineering projects.

Just some of the Hitachi excavator's high-tech features include advanced hydraulics, a powerful undercarriage and a strong engine. There's also an array of safety mechanisms, as well as components designed to minimise environmental impact.

Advanced hydraulic system

The boom circuit, assisted by the boom's weight when it lowers, recirculates pressurised oil. Consequently, the arm receives extra oil and, when the boom and the arm work together, the arm gains speed. It's possible to control this oil flow via a variable throttle located in the arm circuit.

The EX1200-6 offers three work modes, which can be changed via a switch. These are normal, boom-priority and swing-priority. Boom-priority is ideal when the Hitachi Excavator is functioning within a small cycle of digging, swinging and dumping because it increases the boom's raise speed. Meanwhile, swing-priority is better for big cycles because it boosts the speed of the swing.

Powerful undercarriage

The EX1200-6's powerful undercarriage increases its durability, even in difficult conditions. Large track links ensure optimal performance on tough, uneven ground, while the idler pedestal has gained 90% in contact length (in comparison with the previous model), maximising its longevity. In addition, the idlers, rollers and sprocket teeth are all wider.

Ergonomically designed cab

An ergonomically designed cab promotes the operator's comfort, boosting productivity and reducing fatigue. The cab offers plenty of space, an extra-wide seat and short-stroke levers supported by arm rests. Visibility is exceptional, thanks to expansive glass windows, and pressurisation wards off dust and debris. There's also insulation to keep out vibration and sound, plus an overhead LED light, which enables night operation.

Safety features

Safety is central to the Hitachi EX1200-6 Excavator. This starts with the cab, which features an integrated headguard, to provide protection from falling objects. Moreover, the cab can be accessed safely via extra-wide sidewalks and big handrails, which meet the European Norm (EN). At night, angle-adjusted headlights provide excellent visibility and a step light switches on after key-off, helping the operator to alight easily. There's also a shut-off lever, to prevent unwanted movement of the EX1200-6, plus an evacuation hammer, an engine stop switch and a recoiled seat belt, among many other safety features.

Environmentally aware

The designers of the Hitachi Excavator included numerous components intended to minimise the impact of the EX1200-6 on the environment. The brand new engine aims to decrease emissions of particle matter and NOx, plus a variable-speed fan is attached to the oil cooler. Rather than operating at a consistent rate, this fan adjusts according to conditions, so that energy isn't wasted.

The Hitachi Excavator also contains many recyclable parts, such as an aluminium radiator, an oil cooler condenser and resin elements. Lead is absent from many components, including the wire harness covering and the control unit, and there is no asbestos whatsoever.

Straightforward maintenance

As with any heavy machinery, consistent maintenance of the Hitachi 1200 Excavator is vital for optimum performance and long life span. Fortunately, its design allows for a simplified maintenance process. Central to this is the EX1200-6's layout, which provides easy access to every device via wide walkways. There's also a handy optional side ladder.

The radiator and oil cooler are positioned next to one another, boosting the efficiency of the cooling process and reducing the amount of time needed for cleaning. Meanwhile, the SC paint that covers the EX1200-6 can be washed with water, while an auto dust ejector keeps dust and particles out of filters. Consequently, the hydraulic oil filters can be expected to last for 1,000 hours, rather than 500.

Among the Hitachi EX1200-6 Excavator's many other maintenance-friendly features are an electric grease gun for lubricating the swing circle and bucket pin, an easy-to-replace air conditioner filter and a switchboard located in the rear of the cab. In addition, the Hitachi MIC Mining System keeps an accurate record of operating conditions and warnings.

drew-mcphersonDrew's Review

When it comes to hydraulic excavators, the Hitachi EX1200-6 Excavator is seriously impressive. Packed with killer features, it takes the excavating process to a whole new level. If you're looking for an excavator that's safe, efficient, productive and environmentally-friendly, then it's pretty hard to beat. That said, the EX1200-6 is a bit of a giant, best suited to major construction, quarrying and mining projects.

Hitachi has redesigned several of the excavator's components and made some cracking additions. I'm especially impressed with the advanced hydraulic system, which is so efficient. You get to choose between three work modes, so the EX1200-6 always works in the best way for the job at hand, without wasting precious time and energy.

But that's just the tip of the iceberg. If you're thinking of renting the Hitachi Excavator, then it's worth knowing about these features, too:

1) The undercarriage is unbelievably strong. Hitachi has put a lot of thought and resources into revamping the EX1200-6's undercarriage. In fact, the EX1200 specs will blow you away. Think huge track links, idlers, rollers and sprocket teeth. Even when you're working in tough conditions, this Hitachi Excavator has the size and ruggedness to handle them.

2) The ultra-comfy cab. If you've ever sat in a cab for a few hours, you'll know how important comfort is. The Hitachi EX1200-6 Excavator's cab is really spacious, plus it comes with all sorts of comfort-adding elements, such as huge windows, pressurisation and excellent insulation.

3) Safety features. The designers of the EX1200-6 were definitely thinking about safety. There's an integrated headguard in the cab, angle-adjusted headlights, a shut-off lever, an evacuation hammer and loads more features.

The EX1200-6 is a winner, for sure, but that doesn't mean you should go jumping into a big decision. Getting the right machine is important when you're working on a large-scale job. So, before buying the EX1200-6, have a chat with someone who knows all about it – someone who's had actual experience.
