Komatsu W30 to W120: decoding the letter, the number and the dash
Komatsu wheel loader names like W30, W60, W70-3, W90-3 or W120-3 actually belong to two parallel naming families: the shorter "W" designation used for compact or older size classes, and today's more common "WA" designation for current mainline production. SpecCodex lists 104 models under "Komatsu Wheel Loader" spanning both spellings.

The number after the letter roughly places a machine in a size class: low numbers like W30 mark compact loaders, mid-range ones like W60 or W70 the classic construction-site loader, and higher numbers like W120 already larger construction and industrial machines. The dash followed by a digit – such as "-3" on W70-3 and W90-3 – is not a model variant but purely a generation marker: according to industry sources, this dash number signals an updated engine, hydraulics and cab within the same size class.
For a used loader, what matters most is the condition of the bucket cutting edge and the lift-linkage bushings, since these wear parts directly determine remaining service life. The smallest machines in this line sit at around 21 kW of engine power and 3,719 kg operating weight according to the database – typical compact-class figures, well below the large construction models.
In short: "W" or "WA" marks the product family, the following number the size class, and the dash the generation – W30, W60, W90-3 or W120-3 can be roughly placed this way, even though power and weight still vary noticeably within one size class depending on equipment.

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.
