The latest version of the Demag AC 500-8 now meets with Tier 4 standards and means the product is now available to the North American market as well as the European market, where it meets Euromot regulations.
In addition to the emissions upgrade, the crane has an updated IC-1 Plus control system, helping to give maximum lifting capacity, depending on the slewing angle, for any configuration.
Previously the system limited lifting capacity to a pre-calculated, 360° load chart that was based on the most unstable position of the crane.
The new system allows the vehicle to perform tasks typically requiring higher capacity cranes and also creates the possibility of using less counterweight compared with 360° lifting capacities.
Terex said, “Instantaneous capacity calculations allow customers to take full advantage of the maximum lifting capacity available at any given slewing position for any crane configuration. This advantage is particularly useful when working with reduced outrigger settings and reduced counterweight.”
The all-terrain crane has a carrier length of 17.1m, with a maximum system length of 145.8m with a luffing fly jib.
Improvements in design were made to the main boom cross-section as well as the reinforced sideways superlift.
