Demag AC 500-8 Specifications
Demag AC 500-8
(Cranes, Hoists & Material Handlers : All Terrain Cranes)
The Demag product line was acquired by Tadano and the Demag AC 500-8 is now branded as the Tadano AC 8.500-1 All Terrain crane.
This model features a patented Sideways Superlift (SSL) that ensures enormous lifting capacity enhancement and boosts the shortest 8-axle crane in its class with a carrier length of just 17.1m.
This model features a star-type outrigger design giving enhanced stability, short rigging times, and optimized transport weight and dimensions for all attachments.

A long reach
Even though it has a compact design, the Demag AC 500-8 has an enormous reach: With a luffing jib, it reaches an impressive maximum system length of 145.8 meters, which it combines with enormous lifting power thanks to a number of engineering advantages.
Enhanced lifting capacity with IC-1 Plus
Thanks to its innovative IC-1 Plus control system, the Demag AC 500-8 can even handle lifts that are normally the exclusive job of larger cranes. The system is designed to calculate the crane’s lifting capacity for every position of the boom subject to the slewing angle of the superstructure, in real-time. 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 asymmetric outrigger setup.
Powerful in all lifting capacity ranges
The Demag AC 500-8 is a true powerhouse that can deliver enormous lifting power every day regardless of the lifting configuration it uses. There are two engineering details that are responsible for this: the extra strength provided by the Sideways Superlift system and the standard star-type outriggers, which reduce system deformation noticeably and accordingly provide for stability at higher lifting capacities.
