Hitachi wheeled excavators EX60WD and Zaxis ZX130W to ZX220W – W for Wheel, the number as weight class, generations -3 and -6, Isuzu engines 4BG1 to 4HK1, 49 to 122 kW
Hitachi's wheeled excavators are the wheeled versions of the Zaxis range for the European market, where the excavator on wheels is the standard machine in road and sewer work; the EX60WD-2 of the 1990s stands at the start, the Zaxis models from 2001 form the programme. The type logic: ZX stands for Zaxis, the number gives the weight class in hundreds of kilograms – ZX130W about 13 t, ZX170W 17 t, ZX210W 21 t – W for Wheel, the wheeled excavator, the digit after the hyphen the generation: -3 from 2006 with Stage IIIA, -6 from 2016 with Stage IV. The engines come from Isuzu – 4BG1 and 6BG1 in the early, 4HK1 and 4JJ1 in the younger models – as in all Hitachi excavators.

The register lists 11 versions with 49.2 to 122.3 kW from four- and six-cylinders of 2,955 to 6,494 cm³ at rated speeds of 2,000 to 2,500 rpm and operating weights from 6,780 to 22,629 kg.
Hitachi's wheeled excavators are built for Europe at the Amsterdam plant, which pairs the Japanese upper structures with European undercarriages, offset booms and outriggers; the hydraulics are those of the crawler excavators, which secures Hitachi its reputation for fine control on wheels too.
On used machines, operating hours, play in slew ring and boom bearings, the condition of tyres, outrigger pads and oscillating axle, leak-free cylinders and swivel joint and, on -6 models, the aftertreatment service history are what count.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
