From plant to trees for Terex crawler
28 November 2014 by Daniel SearleA Terex CC 2800-1 crawler crane purchased by German crane company Mobi-Hub was taken directly from the manufacturing facility to a wind turbine erection site in a forest in Koblenz.
The crane was taken from Terex's manufacturing facility at Zweibrücken to the Koblenz site, where the wind turbine was erected for Enercon.
The turbine had a hub height of 130m and required three main lifts, covering the 48t nacelle, 71t generator and finally the 68t rotor.
The CC 2800-1 was set up with a 138m S7 boom with 12m fixed jib, and 180t of counterweight.
Challenges included navigating a narrow access path to the site, which was located in a forest, and assembling the boom on sloping terrain which limited the positioning of the assist crane.
Frank Strempel, head of large cranes at Berlin-based Mobi-Hub, said: "On top of that, we had to use the suspended superlift tray with a weight of 325t when erecting the boom."
The team of six assembly technicians from Mobi-Hub, assisted by Terex service technicians, completed the assembly of the crane in two days.
