Demag – other mobile cranes registered as trucks: the AC (All Terrain Crane) series, lifting capacity in tonnes as the type name, 205 to 448 kW, kerb weight 32,750 to 96,000 kg
Demag was a German crane maker whose mobile-crane division belonged to Mannesmann and later to Terex, before the Japanese group Tadano took it over in 2019; in this register the vehicles appear as trucks because mobile cranes need a standard truck registration to travel on public roads. The AC range stands for "All Terrain Crane", with the attached number giving the maximum lifting capacity in tonnes – the AC 100 thus lifts up to 100 tonnes, the AC 700 up to 700 tonnes. Individual entries come from the Finnish vehicle register, where Demag mobile cranes are listed as "ajoneuvonosturi".

The register lists 37 versions with six- to eight-cylinder engines from 6,370 to 15,930 cc, outputs from 205 to 448 kW, kerb weights from 32,750 to 96,000 kg and gross vehicle weights from 33,000 to 96,000 kg; width ranges from 2,500 to 3,000 mm.
Mobile cranes such as the AC range are used in high-rise and industrial construction, wind-turbine assembly and heavy-lift transport, where their own drive means they can reach the work site without a low-loader; Demag competed here with Liebherr and Grove.
When buying a used mobile crane, what matters above all is the operating hours on the hoist and telescopic boom, the condition of the hydraulic cylinders and hoses, and wear on the outriggers and axles from the high operating weight; servicing, inspection and spare parts today run through Tadano or specialist crane-service companies.

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.
