Terex hydraulic excavators TXC140 to TXC520 and 1604 to 1804 – Doosan technology under the Terex name and the Atlas years: 70 to 245 kW, 13 to 51 t
The crawler excavators under the Terex name have two fathers, and the register shows both. The TXC range – TXC140LC to TXC520LC in generations -1 and -2 – arose from a 2003 agreement with Doosan: Terex sold the Korean Solar-series excavators in North America and Europe under its own badge, with Doosan engines DE58, DL06, DE12 and DV11, as the register rows prove; the number gives the weight class in hundreds of kilograms, LC the long-crawler undercarriage with a longer footprint. The agreement ended in 2009 when Doosan began distributing its excavators itself. The 1604LC, 1704LC and 1804LC with Deutz BF6M 1013 engines, by contrast, come from Germany – from the years when Terex owned the excavator maker Atlas Weyhausen of Ganderkesee (2001 to 2010); TC125 and 180LC-2 are further types of those years.

The register lists 23 versions with 70.1 to 244.6 kW from four- and six-cylinders of 4,031 to 11,061 cm³, torque from 392 to 1,542 Nm at 1,750 to 2,200 rpm and operating weights from 12,800 to 51,392 kg.
For operators that means: a TXC excavator is technically a Doosan Solar, a 1604LC an Atlas – parts, manuals and workshop knowledge run through the respective brand of origin, not through Terex.
On used machines, operating hours, play in slew ring and boom pins, the condition of the undercarriage (tracks, rollers, sprockets), leak-free cylinders and pumps and parts availability through Develon (formerly Doosan) or Atlas 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.
