High power, low fuel consumption and emissions are claimed for Hitachi’s new excavators
The machine comes with added protection for key components and is said to offer reliability and high availability. Enlarged track guards reduce potential damage to track links. The front attachment’s durability has been enhanced by HN bushings to strengthen the brackets on the boom end and foot, and reinforced resin thrust plates on the boom.
The 210kW Zaxis-6 medium excavator incorporates high-quality components such as the in-cab console, which is made of weather-resistant AES-grade resin that prevents damage from UV rays. The upper structure has high-quality sealant (around the cooling package) and acoustic materials to ensure the machine’s long-term cooling and low-noise performance.
TRIAS II technology helps boost efficiency by reducing hydraulic loss. This results in a 15% fuel saving in ECO mode with the same level of productivity. The aftertreatment device results in fewer emissions and a quieter performance. It 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 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.
Similar performance upgrades meanwhile are fitted to the new 197kW ZX300LCN-6 and 140kW ZX250LC-6 excavators from the firm.
