The Hitachi ZX800 is a model in the Hitachi Hydraulic Excavator series. The engine delivers 338.5 kW, has 6 cylinders, with a displacement of 15,682.4 cm³. Torque is 1,863 Nm. Rated speed is 1,800 rpm. The unladen weight is 73,900 kg. Ground clearance is 880.9 mm. The tank holds 901.3 litres. Maximum torque is reached at 1,500 rpm. The pump delivers 30.3 l/min. The hydraulic tank holds 670 litres. Working pressure is 343.4 bar. The cooling system holds 107.1 litres. The oil fill is 55.3 litres. The electrical system runs on 12 V. The engine fitted is the BB-6WG1T. The Hitachi Hydraulic Excavator series covers 158 models. Rated output within it ranges from 42.4 to 481.7 kW; the ZX800 sits in the upper part of that range with 338.5 kW. Its immediate neighbours are the EX700 below it with 309 kW and the ZX850-3 above it with 343 kW. Unladen weight within it ranges from 8,143 to 108,000 kg; here the ZX800 sits in the upper part of that range with 73,900 kg. 357 Hitachi models across 24 series are on record.

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.
  • 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.
