Terex-Demag unveils CC 2800-1 NT crawler

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 600 tonne capacity CC 2800-1 is to erect groups of wind turbines on the often-remote wind farm sites where access roads are 5 m wide. Turbines with hub heights up to 142 m can be accommodated.

The crane can travel between turbines on site fully erected with its long boom system and counterweight. 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 for narrow access. It also has a counterweight suspension system, remote control operation and more powerful track drives.

The CC 2800-1 NT can erect itself, with 102 m of SH/LH SGLmax S7 boom and 12 m luffing fly without an assist crane. Other features include a low centre of gravity and low ground pressure, Terex-Demag 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.
