Terex/Demag AC: the number is the tonnage class, the history is Demag
The "AC" (All Terrain Crane) code plus a number follows, as with most mobile crane makers since the late 1990s, the maximum lifting capacity in tonnes: an AC 100 lifts roughly 100 tonnes, an AC 140 roughly 140 tonnes. In SpecCodex, the 41 recorded models span 19,500 to 108,000 kg of vehicle weight, reflecting the range from compact city cranes to heavy multi-axle units.

The brand itself has had a turbulent path: the Zweibrücken plant belonged to Demag until 2002, then to Terex (briefly as "Terex-Demag"), the Demag name returned in 2016, and after Tadano's 2019 acquisition, AC cranes have carried the Tadano brand since 2021. A "Terex All Terrain Crane" in SpecCodex is therefore technically related to today's Demag/Tadano AC models.
A hyphenated value often appended (e.g. "-5") states the chassis axle count — an important factor for road registration and axle load. In the database, engine output ranges from 156 to 440 kW, torque from 540 to 3,186 Nm, and displacement from 5,961 to 15,928 cm³.
When buying used, check the condition of the boom telescoping section and outriggers, review the crane logbook for load-cycle counts, and confirm whether original parts are still available through today's brand owner, Tadano. Models such as AC25, AC70, AC100 and AC140 illustrate the spread of tonnage classes.

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.
- Ask about parts availability for this build year — the running costs hang on it.
