Demag AC 220-5 all-terrain crane

The Demag AC 220-5 all-terrain crane features an overall length of 14.52 m and width of 3 m, making it one of the most compact cranes in the 220-t capacity class. It has a maximum main boom length of 78 m, and is able to reach up to 99 m with an optional main boom extension.

Thanks to its innovative IC-1 Plus control system, the five-axle AC 220-5 can handle lifts that are normally carried out by larger cranes. To do this, the system calculates the crane’s lifting capacity for every boom position as a function of the superstructure’s slewing angle, and in real time to boot. This means that the lifting capacity for a specific radius is no longer limited to the lowest value for a pre-calculated 360° lifting capacity, as used to be the case. Instead, the crane can always take full advantage of the maximum available lifting capacity. This advantage is particularly useful when it comes to lifts requiring an asymmetrical outrigger setup.

The AC 220-5 is also cost-effective. Many of the components in Demag five-axle machines – such as hoist 2, main boom extensions, runners, swing-away rooster sheaves and heavy-lift attachments – are interchangeable, resulting in easy maintenance and thus lower operating costs.

The AC 220-5 is powered by Scania DC13 diesel engines with an output of 331 to 405 kW, complying with EU Stage V / Tier 4f (405 kW) or EU Stage III A / Tier 3 (331 kW) regulations. The power delivered by these engines is safely and reliably brought to the road by fully automatic ZF TraXon transmissions with 12 forward gears and two reverse gears via three or four driven axles. In addition, five-axle steering, combined with independent rear axle steering and dynamic launch control, makes the AC 220-5 highly manoeuvrable.
