The CC 9800, operated by Sarens, and with a maximum lifting capacity of 1,600t and a load moment of 26,930tm, was used to erect a 6MW capacity E-126 turbine at the port. This included lifting the nacelle, with a weight of 128t; the generator, with a weight of 220t; and the hub with steel blades installed, which weighed 303t. The generator’s axle was installed at a height of 135m, and the rotor had a diameter of 127m. This gave a total installed height just under 200m.
“The size of this turbine is already pretty exciting for the assembly team,” said crane operator Enrico Wunderlich.
“The sheer magnitude of it is way beyond anything that has ever been done before. The complete upper part, with its turbine house, hub and blades, weighs an impressive 650t.”
Terex said the CC 9800 has been optimised for the installation of such increasingly frequent large-scale wind turbines, including lifting complete subassemblies. Enercon is installing several E-126 wind turbines at the port.
“This is exactly the type of crane we need,” said Sarens owner and manager Hendrik Sarens. “Earlier on, we had to use two large cranes for a project of this magnitude, and the process involved lifting the generator and the rotor hub in several steps, which cost a lot of time and money.”
