The new excavator benefits from the fuel economy of this Stage V compliant machine. Its ‘HIOS III’ hydraulic system achieves higher levels of productivity with better fuel consumption than previous models, helping to reduce running costs. Operators can also control the fuel efficiency and costs with the all new ‘Eco gauge’, which is clearly visible on the large LCD monitor. It can be used with a broad range of Hitachi attachments, such as tiltrotators and buckets, breakers and sorting grabs, to suit the application. These are easily changed using the enhanced attachment support system and can be conveniently transported using the optional trailer support package. The new model can also be fine-tuned to suit the operator’s preference and job site requirements.

The redesigned cab is spacious, offering comfort with low noise levels and less vibration than the previous generation. Operators are said to feel less tired at the end of their shift thanks to the synchronised motion of the seat and console. Easy operation also comes from the new ergonomic design of the console and switches; convenient access to the controls and features such as cruise control, automatic transmission and the optional ride control system that suppresses vibrations from the front attachment.
 

Increased safety

The cab also offers an enhanced view of the job site to protect operators and the machine from potential hazards. Visibility is boosted by a 270o bird’s eye view using the aerial angle camera system. Operators can choose from six image options on the monitor to view the immediate environment. Vision through the cab’s front window is also improved by the slim steering column (with wider adjustment angle) and smaller steering wheel. To enable operators to work more confidently and productively, even in challenging conditions, the Zaxis-7 wheeled excavators are fitted with new features such as LED work lights, a windscreen wiper with an increased sweeping area and larger mirrors. Heated mirrors are also available as an option. For additional safety, the upper structure and front attachment will lock in place when the machine is in the correct position for driving on public roads.

Fleet management and remote access

Hitachi remote monitoring systems enable owners to feel in total control of their fleet and workload with access to vital data courtesy of ‘Owner’s Site’ and ‘ConSite’. 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, and the ConSite Pocket app shows real time alerts for any potential issues. Machine software updates can be carried out remotely by dealers for added convenience using ‘ConSite Air’. This feature also enables Zaxis-7 excavators to be monitored with Hitachi’s diagnostic tool. In addition, a unique innovation continuously monitors the quality of engine and hydraulic oil, 24/7. Data is transmitted daily via two oil sensors to Global e-Service. These detect if the oil quality has deteriorated, due to contamination or low viscosity. It reduces maintenance and unscheduled downtime, and gives owners peace of mind thanks to scheduled servicing and a higher resale value.

“We’re delighted to introduce the largest Zaxis-7 wheeled excavator model,” says Hitachi Construction Machinery (Europe) NV Excavator product manager Wilbert Blom. “We’ve had a hugely positive response from customers to the new range so far, and we hope the ZX220W-7 will be equally well received. It offers outstanding versatility for a wide range of applications when used with Hitachi attachments, and delivers an exceptional performance allowing our customers to create their vision.”
