Terex Cranes has “treated” its DemagAC 500-8 all terrain crane to an upgrade to enhance the machine’s technical characteristics. The latest version complies with the United States’ Tier 4 engine exhaust emission standards, which means that it now has access to the US market. The first order from the USA has already been placed, and the new Demag AC 500-8 will be delivered mid year. As for the European markets, the crane also has boundless access as it complies with Euromot 4 standards.
Along with the crane’s emission upgrade, another technical highlight is the IC-1 Plus control system. The IC-1 Plus control system is designed to provide the crane’s maximum allowable lifting capacity, based on the slewing angle, for every crane configuration. 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.
Instant 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.
It allows the crane to do jobs where higher capacity cranes are typically needed, Terex said. This comes with an added benefit: 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.
The carrier length of only 17.1 meters means it is still the most compact eight-axle machine in its class, the manufacturer said. It can achieve a maximum system length of 145.8 meters with a luffing fly jib. Power across the full lifting capacity range is enhanced by features such as the improved design of the main boom cross-section and the reinforced sideways superlift.
The star shaped outrigger design means minimal carrier deflection during maximum capacity lifts. In addition, the crane has a short setup time and comfortable working conditions.
