Ematec, a specialist supplier of lifting equipment for the wind-power industry, has returned from the WindEnergy 2024 trade fair in Hamburg with a series of project enquiries.
“The response at the trade fair was outstanding, and it was once again demonstrated that we are recognized as the leading provider of technologies for single-blade assembly of rotor blades. Our RBC-D generation yokes are still the benchmark for labor safety and efficiency,” said Julian Eberhard, CTO of Enercon.

There was interest in a handling upgrade that Ematec’s RBC yokes offer combined with Seasight Solutions’ Automatic Positioning System. Here, two propellers are flange-mounted to the traverse so that guide ropes can be dispensed with when installing the rotor blades.
“Our joint customer Enercon is already benefiting from this combination on its construction sites, which not only simplifies and speeds up processes but also increases safety,” Eberhard said.
The two propellers can compensate for higher wind speeds and are better at stabilizing the rotor blades, compared to the previous method of using guide ropes controlled by workers on the ground. This makes it possible to install rotor blades at wind speeds up to 10 m/s. The traditional approach worked at wind speeds up to 8 m/s, depending on the rotor blade type.
“On average, using the APS saves us 2.3 working days per construction site, when otherwise installation would have to be put on hold because of weather conditions,” said Klaas Schumann, Enercon site engineer. Doing away with the guide ropes has also reduced the working radius required for rotor blade installation.
Thanks to the two original systems, ENERCON has already been able to improve and speed up the assembly work in various projects such as Flöthe, Fuchstal, and Liebenau in Germany, as well as in the large-scale Horizonte project in Chile.
