Hitachi UK reveals its biggest Zaxis-7 excavator
By Leila Steed29 March 2022
Hitachi Construction Machinery (UK) has revealed the largest wheeled excavator model in its new Zaxis-7 equipment range.
Described as a highly versatile, the Hitachi ZX220W-7 excavator has an operating weight of 22 tonnes and is fitted with a Stage V engine.
Wilbert Blom, Hitachi Construction Machinery (Europe) NV Excavator Product Manager, said, “We’re delighted to introduce the largest Zaxis-7 wheeled excavator model.”
“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...”
According to Hitachi, the excavator’s HIOS III hydraulic system offers greater productivity and better fuel consumption than previous models, which reduces running costs, thereby allowing equipment owners to increase profits.
Hitachi added that “operators can also control the fuel efficiency and costs with the all-new ECO gauge, which is clearly visible on the large LCD monitor”.
The ZX220W-7 comprises a single-piece undercarriage and is available with either standard 2,550mm axles or wider 2,750mm axles, and a range of counterweights for increased lifting capacity and stability.
The new model extends the Zaxis-7 equipment range, joining the company’s ZX150W-7, ZX155W-7 and ZX180W-7 excavators and the ZX135W-7 and ZX175W-7 short-tail swing models.
Like other machines in the range, the model features Hitachi’s redesigned Zaxis-7 cab, which is larger than the company’s previous generation of cabs and also offers increase noise and vibration protection.
“Operators will feel less tired at the end of their shift thanks to the synchronised motion of the seat and console,” said Hitachi.
“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.”
Unlike Hitachi’s previous generation of excavators, Zaxis-7 wheeled excavators include LED work lights, a windscreen wiper with an increased sweeping area, and larger mirrors.
The ZX220W-7 is equipped with the Aerial Angle camera system, which provides a 270-degree bird’s-eye view of the machine and its environment.
“Operators can choose from six image options on the monitor to view the immediate environment,” said the manufacturer.
On the technology side of things, the ZX220W-7 incorporates Hitachi’s ConSite and Owner’s Site remote monitoring systems.
Together with Consite Pocket app and ConSite Air, the telematics systems provide fleet owners and managers with operational data, real-time alerts and enable software updates to be carried out remotely.
“In addition, a unique innovation continuously monitors the quality of engine and hydraulic oil, 24/7,” said Hitachi.
“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.”
