Terex Cranes has upgraded its Demag AC 500-8, enhancing the machine’s technical characteristics.

The latest version of the crane complies with the United States’ Tier 4 emission standards, which means that the unit now has access to the US market. As for the European market, it complies with Euromot 4 standards.

Along with the crane’s emission upgrade, the manufacturer has added the new IC-1 Plus control system. This control system is designed to provide the crane’s maximum allowable lifting capacity, based on the slewing angle, for every crane configuration. 

Terex said: “The new control system no longer limits the maximum lifting capacity to a pre-calculated, 360° load chart which was based on the most unstable position of the crane. Instantaneous capacity calculations allow customers to take full advantage of the maximum lifting capacity available at any given slewing position for any crane configuration.”

The manufacturer said this advantage is particularly useful when working with reduced outrigger settings and reduced counterweight. It enables the Demag AC 500-8 to perform jobs where higher capacity cranes are typically needed.

“For many applications, the IC-1 Plus control system not only uses the full potential of the crane’s lifting capacity, but also creates the opportunity to use less counterweight as compared to the 360° lifting capacities. This results in reduced transport costs,” Terex said.

The AC 500-8 has a carrier length of 17.1m and can achieve a maximum system length of 145.8m with a luffing fly jib. It features an improved main boom cross-section design and the reinforced sideways superlift.

The star-shaped outrigger design provides the required strength needed for minimal carrier deflection during maximum capacity lifts.

Terex said the first order from the USA has already been placed, and the new machine will be delivered mid-year.
