Hitachi introduces new ZX250LC-6 excavator

Hitachi Construction Machinery (Europe) NV (HCME) will present the ZX250LC-6 medium excavator at Bauma. Designed and engineered to meet the demands of general construction companies and contractors, it offers the highest level of performance, but without compromising on the increasing demand for operational efficiency.

The new model incorporates unique Hitachi technology developed specifically for the Zaxis-6 medium excavator range, and high-quality and durable components that contribute to its exceptional reliability, in line with Hitachi’s overall goal to build the ultimate excavator. With incredibly versatile features, it is suitable for a wide range of industry solutions.

The ZX250LC-6 is equipped with a TRIAS II system that reduces the amount of hydraulic oil returned to the tank due to the cooperative control of the pump and valve. This results in a 19% fuel saving in ECO mode (10% in PWR mode), with the same levels of productivity.

Another example of advanced technology is an after-treatment device that results in fewer emissions, ensuring compliance with EU Stage IV regulations. Noise levels are also reduced by the device, which consists of a diesel oxidation catalyst, urea mixing pipe, (selective catalytic reduction) SCR system and silencer. The SCR system injects urea into exhaust gas to reduce nitrous oxide.

The new Zaxis-6 medium excavator incorporates high-quality components such as the in-cab console, which is made of highly durable AES-grade resin that resists damage from UV rays. The risk of oil leakage is reduced by a rubber hose fitted with a flange on the hydraulic return pipes, and O-rings on the control valve and swing motor that are made from fluorine. This material withstands high oil temperatures, reinforcing the reliability of these components.

The durability of the ZX250LC-6 is enhanced by three track guards, as opposed to one on the ZX250LC-5. This strengthens the undercarriage and helps to reduce damage caused to the track link. Covers on the platform walkway have also been reinforced, which contributes to the machine’s safe working environment.

Demonstrating the new model’s versatility, the tilting rotator and tilting bucket modes are included within its attachment support system. These and nine other modes can be registered on the monitor for easy fitting of attachments. Two extra spools in the control valve make it easier to install attachments that require multiple, large volumes of oil and on two-piece boom models.

Burkhard Janssen, General Manager of the Product Management and Engineering Department at HCME, communicated customer requirements from the field to the development team in Japan. This resulted in the new range of excavators including the ZX250LC-6. “Our target was to achieve fuel efficiency with the Zaxis-6 range. We couldn’t restrict the power of the engine, as we wanted to maintain controllability and productivity – this was a huge challenge,” he explains.

“The most significant factor was the development of the new TRIAS II hydraulic system to decrease fuel consumption. Whereas other excavator manufacturers only do this via the engine, Hitachi does not compromise on productivity to achieve this.”
