Sumitomo Hydraulic Excavator: reading the SH number and the dash generation
The "Sumitomo Hydraulic Excavator" bucket on SpecCodex covers 40 live-listed models from the Japanese crawler-excavator family. The code follows a clear pattern: "SH" plus a number (100, 120, 130, 160, 200, 220…) names the size class, while a hyphenated digit such as "-2", "-3" or "-5" marks the production generation, referred to by the maker as the "dash" level.

Each new dash generation at Sumitomo lines up with a new emissions tier: older dash levels met EU Stage IIIA or EPA Tier III, while current lines (dash-6/-7) reach EPA Tier 4 Final and EU Stage V with a diesel particulate filter and SCR aftertreatment. Models without a dash digit, such as the plain SH200 in this bucket, are usually older or export-market versions outside that scheme.
The recorded spread: engine output 60 to 397 kW, operating weight 11,480 to 80,100 kg, displacement 2,900 to 15,700 cm³. For a subset of models, 4- to 6-cylinder engines and torque figures of 294 to 539 Nm are also on file.
For a used machine, the dash generation drives the service checklist: newer dash generations with DPF/SCR need their regeneration cycles and AdBlue system checked, while older dash-2/3 machines call for a closer look at the hydraulic pump, valve block, and undercarriage for leaks and wear.
In short: the SH number is the size class, the dash digit is the generation and, indirectly, the emissions tier. Only the nameplate confirms it — the model name alone does not.

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.
