Hitachi ZX – what the number and letters reveal about weight class, LC/US/W undercarriage variants and the adjustable boom option across the ZAXIS range
Hitachi codes usually start with ZX, short for the ZAXIS line. The following number places the model in an approximate operating-weight class, letters such as LC, US or W describe the undercarriage and configuration, and a dash number at the end marks the generation.

LC marks a widened undercarriage for extra stability, US denotes ultra-short-tail models with a compact rear overhang for tight jobsites, and W marks wheeled machines. Current models run as ZAXIS-7, while older stock is still labelled -3, -5 or -6.
Alongside these sits the older EX line, such as the EX700: mechanically simpler than the ZX models, with less electronics, but built rugged for heavy continuous duty.
Alongside the one-piece monoboom, many ZX models offer a two-piece adjustable boom whose knuckle can swing sideways; this allows digging along walls or pipelines without having to square the machine itself up to them, though at somewhat lower breakout force than the rigid monoboom.
The collective entry spans small excavators from around 42 kW up to large machines above 480 kW. When buying used, check the hour meter along with the slew ring, boom-and-bucket linkage bushings and any leaks at the hydraulic cylinders.
In short: ZX plus size number plus undercarriage letter plus generation digit make up the full code, as seen on models like ZX120, ZX200 or ZX330.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
