Hitachi Construction Machinery (Europe) NV has introduced the 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. Hitachi says 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.
Updates on the ZX490LCH-7 compared to the previous model include an improved production of 7 per cent and improved front speed for loading due to a new HIOS V hydraulics system.
The fuel efficiency of Zaxis-7 large excavators can also be controlled by using the new ECO gauge, which is visible on the cab’s multifunctional 8” monitor.
In the cab, new features include the synchronised motion of the seat and console to reduce operator fatigue as well as an adjustable console height with three positions to choose from. The adjusted boom and arm speed (hydraulic flow) allows for a smooth performance, Hitachi adds.
Operators can control their own safety, as well as that of those around them, with the Aerial Angle camera system, which provides a 270-degree 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.
For increased stability, the ZX490LCH-7 SLF has a heavier HD-counterweight and a 500mm extendable undercarriage. When the undercarriage is retracted, this also contributes to easy transport.
Hitachi’s remote monitoring systems Owner’s Site and ConSite give owners access to machine data and tools. Both systems send operational data via GPRS or satellite from the excavator to Global e-Service on a daily basis. ConSite summarises the information in a monthly email, while the ConSite Pocket app shows real-time alerts for any potential issues.
The quality of the engine and hydraulic oil is monitored continuously by a unique Hitachi innovation. Two sensors detect if the oil quality has deteriorated and data is transmitted to Global e-Service.
