Hitachi Construction Machinery is introducing its largest Zaxis-7 model in its extensive super long front excavator range.
The ZX490LCH-7 HE16LD with 16m reach has a longer boom and arm and heavier counterweight than the standard ZX490-7 model. It is ideal for excavation work, as well as dredging rivers and lakes, bank maintenance and lighter, slope-finishing tasks. Due to the proportions of the boom and arm, the 49-tonne model can also be used for loading, as trucks can be conveniently positioned close to the machine.
Like all Zaxis-7 large excavators, the ZX490LCH-7 super long front (SLF) puts owners and operators in complete control. The Stage-V compliant model has an industry-leading cab with first-class comfort and safety features. Its exceptional reliability, efficiency and productivity provide owners with opportunities to increase profits and reduce costs.
Productivity on site will rise, says Hitachi, due to an improved production of 7% (in PWR mode) for the ZX490LCH-7, which has the same size engine as the larger ZX690-7 model. An improved front speed for loading also increases productivity – a result of the new HIOS V hydraulics system, which is fine-tuned for optimum control of super-long-front applications and also reduces fuel consumption.
The fuel efficiency of Zaxis-7 large excavators can also be controlled by using the new ECO gauge, clearly visible on the cab’s multifunctional 8in monitor. Besides reducing costs, better fuel economy has a positive impact on environmental performance. The ZX490-7LCH SLF is Stage V-compliant thanks to the combination of the SCR (selective catalytic reduction) system, DOC (diesel oxidation catalyst) and CSF (catalysed soot filter).
Feel the difference
The state-of-the-art, ultra-spacious cab provides the perfect working environment. It offers operators ultimate comfort and quality, with reduced noise and vibration levels in the cab.
New features include the synchronised motion of the seat and console – to reduce operator fatigue – and the adjustable console height with three positions to choose from. The adjusted boom and arm speed (hydraulic flow) allows for a smooth performance, while easy operation comes from the ergonomic design of the console and switches, and the hi-res anti-glare screen is also easier to view.
Job site safety is enhanced by the extensive view from the Zaxis-7 SLF excavator. Operators can control their own safety, as well as that of those around them, thanks to the Aerial Angle camera system. It provides a 270o bird’s-eye view and users can choose from six image options to see the machine’s immediate environment. When working in challenging conditions, new LED work lights and a windscreen wiper with an increased sweeping area further improve visibility.
To ensure optimum stability, the ZX490LCH-7 SLF has a heavier HD- counterweight (9.8 ton) and 500 mm extendable undercarriage. When the undercarriage is retracted, this also contributes to easy transport.
“This is the latest addition to our super long front product range, which ranges from eight to 50 tonnes, and from 10 to 22m reach,” says Burkhard Janssen, product manager special applications and new technologies at Hitachi Construction Machinery (Europe) NV.
“It shares many of the advantages of our Zaxis-7 large excavator range, offering an enhanced experience in the cab for operators, and improved productivity and fuel efficiency to help owners improve their profits. It is also provided with life-cycle support from Hitachi, ensuring ultimate peace of mind.”
