Demag heavy lift spectacular
18 April 2008
In September 2005, Terex-Demag announced it was to launch the 1,100 ton capacity CC 5800 crawler crane. The unveiling of the new model took place at Terex-Demag's crane testing facility in Bierbach, Germany on November 18. In addition, the select audience of about 300 participants from around the world were treated to a spectacular series of announcements.
The main attraction was of course the debut of the CC 5800, which has a maximum load moment of 12,860 tonne-metres. In addition to the 9.8 foot transport width of all components, jib sections can be inserted into the main boom sections to further simplify transport. Operation can either be with up to 492 feet of main boom or a 670 foot combination of main boom and luffing jib, both in SL configuration.
The central base of the CC 5800's slewing ring is connected to four foldable outriggers, which not only allow self-loading and discharging, but also fit straight to the crawlers or can be lengthened to operate the crane in pedestal mode.
What followed at the summit was further extensive explanation of several more Terex-Demag developments in heavy lift crane design. First was the new 661 ton capacity CC 2800-1 NT, a Narrow Track (NT) version of the CC 2800-1, for wind turbine erection, designed to relocate on site fully rigged. Terex-Demag technical director Klaus Meissner explained the different approach his team has taken in designing a 12 foot wide crawler undercarriage with a central beam and outriggers attached at the front and rear. For additional sideways stability outriggers have been attached that can fold up to the crane upper for narrow access. In this way Terex-Demag claims its CC 2800-1 NT has increased sideways stability with a center of gravity at 24 feet and a tipping angle of 14.5 degrees. The crane can lift up to 137 tons on 295 feet of boom.
