Demag AC – road-registered all-terrain cranes from the compact City class to large cranes: AC 40 to AC 700, six to eight cylinders, 205 to 480 kW, operating weights up to 95,750 kg
Demag, which grew out of Duisburger Maschinenbau AG, has built mobile cranes since the 1960s and now operates as part of the crane group Tadano; the AC series denotes all-terrain cranes with road registration that, unlike lattice-boom crawler cranes, drive to the site on their own axles. The type number after AC roughly gives the maximum lifting capacity in tonnes, from the AC 40 with about 40 tonnes to the AC 700 with about 700 tonnes; suffixes such as -1, -2 or -5 mark the series generation, CITY the especially compact city cranes.

The register lists here 26 versions with 205 to 480 kW from six- and eight-cylinders of 6,374 to 15,928 cm³ displacement, operating weights from 32,650 to 95,750 kg, gross weights from 33,000 to 96,000 kg and widths from 2,500 to 3,000 mm.
All-terrain cranes such as the AC series combine the road speed of trucks with the off-road capability of crawler cranes, making them the most versatile construction cranes for changing job sites; alongside Liebherr and Grove, Demag ranks among the established makers of this class and covers the full span with the AC range, from compact city cranes to large cranes for heavy-lift and wind-turbine assembly.
On a used example, the operating hours of the carrier and the superstructure, the condition of the telescopic boom (wear on the slide pads, tightness of the hydraulic cylinders), the operation of the winches and boom extension, and inspection records and maintenance history count, since cranes are subject to regular expert inspections; parts and service run through the Tadano Demag network.

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.
