Hitachi launch new large excavators
Latest next-generation Stage V compliant Zaxis-7 models introduced to European customers
HITACHI have introduced their next generation of Zaxis-7 large excavators to European customers with the launch of new ZX490LCH-7, ZX530LCH-7, ZX690LCH-7 and ZX890LCH-7 Stage-V compliant models.
Fuel savings of up to 20% (PWR mode) compared with previous models are achieved by Hitachi’s HIOS-V hydraulic system, which also enhances efficiency in the swing, boom lowering and arm bucket roll-out.
Productivity is further increased by the improved front speed for loading operations, whilst the increased engine output of the new Zaxis-7 machines contributes to a higher workload.
The fuel efficiency of Zaxis-7 large excavators can also be controlled by using the new ECO gauge on the cab’s multifunctional 8in monitor. The new machines are Stage V-compliant thanks to a combination of SCR (selective catalytic reduction), DOC (diesel oxidation catalyst) and CSF (catalysed soot filter).
The state-of-the-art, ultra-spacious cab offers operators comfort and quality, with reduced noise and vibration levels, both of which are important in the mining and quarrying industries. Other new features include synchronized motion of the seat and console – to reduce operator fatigue – and three-position adjustable console height.
According to Hitachi, job site safety is enhanced by the exceptional view from the Zaxis-7 large excavators. Operators can control their own safety, as well as that of those around them, thanks to the aerial angle camera system. It provides a 270° bird’s-eye view and users can choose from six image options. When working in challenging conditions, new LED work lights and a windscreen wiper with an increased sweeping area further improve visibility.
The undercarriage of the ZX490LCH-7 has robust new components that prevent potential damage. The ZX530LCH-7 model has 30% greater traction force than the ZX490LCH-7 and increased steering force, which is particularly advantageous for manoeuvrability on sites with inclines, such as quarries.
The ZX690LCR-7 and ZX890LCR-7 models are built with reinforced parts that are well suited to the digging and loading of heavy materials. Strengthened to cope with the rigours of mining and quarrying, they are said to provide lower costs over the machine lifetime.
Easy maintenance and cleaning features on all Zaxis-7 large excavators are designed to save operators and owners both time and money. The fuel filter is now integrated with the water separator, and the larger radiator improves heat dissipation and is easier to clean.
Hitachi’s remote monitoring systems, Owner’s Site and ConSite, provide access to vital data and tools. Both systems send operational data via GPRS or satellite from the excavator to Global e-Service on a daily basis. ConSite summarizes the information in a monthly email to owners, while the ConSite Pocket app shows real-time alerts for any potential issues.
