Hitachi displayed three new excavators and a wheel loader at Bauma in April.

The new ZX19-5 mini excavator, to be used on construction projects, is designed to be user-friendly. According to the manufacturer, the Zaxis-5 model offers high levels of performance, stability and easy maintenance.

The boom cylinder, in the new excavator, has been moved on top of the boom to protect from potential damage, making it more efficient when working on narrow spaces, as its front minimum turning radius is smaller.
A new folding travel pedal can now be used instead of the hand lever, improving the operation speed. Other improvements include the placing of the hydraulic hose inside the boom and the addition of a new blade, capable of making digging more precisely.

There is also more space between the operator and the front window and more legroom in the cab. The cab has a new design that features a large LCD monitor located on the right-hand side, displaying the vital technical data, including the machine’s status and settings and a drinks holder for easy access to refreshments.

Security has been improved, with an optional theft deterrent system that requires a four-digit number to unlock before the engine can be switched on.

Hitachi also showcased the ZX300LCN-6 super long front medium excavator. The excavator has a six-cylinder 186kw stage IV-compliant engine, with the highest output in its class, and offers 14% higher productivity in PWR mode.

Delivering lower fuel costs, the machine was specially designed for earthmoving on dredging, bank maintenance and slope finishing projects. The excavator also features a reconfigured lower roller that ensures mud falls out easily, an expansion tank that cools the engine parts, and enlarged track guards.

The tilting rotator and tilting bucket modes are also included within its attachment support system.

The new ZX490LCH-6 large excavator was designed to meet the demands of large-scale construction projects, set to offer a high level of durability without compromising efficiency.

It features a boom reinforced with thicker plates and an undercarriage consisting of robust components such as track link, master pin, idler pedestal and bracket and upper roller bracket.

The large excavator also incorporates an in-cab console, made of weather-resistant AES-grade resin that prevents UV rays damage, and sealant to eliminate any heat deterioration.  These ensure the machine’s long-term cooling and low-noise performance.

This excavator is able to save up to 5% fuel in eco mode with the same productivity as previous models, due to the use of HIOS IIIB technology. The after-treatment device helps the machine produce fewer emissions and to have a quiet performance. Furthermore, attachments to carry on different tasks can be easily fitted to the versatile machine that uses the attachment replacement support system.

Also launched in Munich was the ZW370-6 wheel loader. With enhanced performance and low fuel consumption, the machine employs a new EU Stage IV-compliant engine that does not require a diesel particulate filter, which reduces maintenance costs.

The wheel-loader has a 360° panoramic view from the spacious cab and a rear-view camera, visible on the multifunctional LCD monitor. Less noise can be heard within the cab thanks to an improved sound isolation. A smooth operation is ensured by the optional Joystick Steering System, which enables operators to reach high levels of productivity with effortless steering, it is said.

There are also two types of lift arm available that customers can choose, depending on the required application.
