Terex-Demag shows narrow track crawler
24 April 2008
Shown in iron at the end of July was the new Terex-Demag CC 2800-1 NT crawler crane. A typical application for the NT (Narrow Track) version of the 661 ton capacity CG 2800-1 is to erect groups of wind turbines on the often-remote wind farm sites where access roads are 16 feet wide. Turbines with hub heights up to 465 feet can be accommodated. The crane can travel between turbines on site fully erected with its long boom system and counter weight. To achieve this the NT has a narrow track carbody with full width front and rear outriggers plus side outriggers that can fold up to a vertical position. It also has a counter weight suspension system, remote control operation and more powerful track drives.
The CC 2800-1 NT can erect itself, with 335 feet of SH/LH SGLmax S7 boom and39 feet luffing fly without an assist crane. Other features include a low center of gravity and low ground pressure, Terex said. And the upper works of the NT are the same as the CC 2800-1 so it can be converted to a standard crane.
