ematec AG als Arbeitgeber

The new yoke generation RBC and RBC-D from ematec AG, the Germany-based expert supplier for the wind power industry in action.

The brand-new RBC-D 50 Greenline supports rotor blades with a blade weight of up to 50 tons, thus setting a new quantum leap on the world market. The special highlight: the RBC-D 50 itself weighs just 27 tons.

@ENERCONGmbH1 is the first wind turbine manufacturer to benefit from the new generation of yokes from the technology and innovation leader from the Allgäu region.

ematec's RBC generation rotor blade yokes are the world's first and only single blade yokes that can be automatically and individually adjusted to the respective rotor blade, always balancing themselves. They can accommodate blades between 45 and 110 meters long and stabilize them up to a tilt angle of ±30 degrees, thus preventing uncontrolled movements of the units. For safe handling of the rotor blade, the RBC always finds the exact centre of gravity individually. Two counterweights on the two yoke wings automatically adjust to the centre of gravity - with and without the rotor blade.

The "D" in RBC-D stands for "Double" and means that in addition to the lower telescopic gripper, the upper one is also equipped with fourteen hydraulically moved and gimbaled grip pads.

Further highlights: The hydraulic cylinders of the grabs are equipped with integrated safety valves that make it impossible for the rotor blade to slip out - even in the unlikely scenario of incorrect operation. With a slope height of just about 3.5 meters, the RBC series makes crane management much easier, especially in view of the ever-increasing hub heights of wind turbines.

Ready for use in record time

On the construction site, the RBC yokes are ready for use faster than all other yokes because they automatically move into their operating position. The attachment to the rotor blade also takes place in record time. The RBC yokes need less than 15 minutes for these two steps.

The Green Line variants of the RBC yokes are powered by high-performance rechargeable batteries designed for a working time of 16 hours at temperatures down to -20 degrees Celsius. The battery operation is double redundant. Thanks to ematec's Green Line technology, wind turbine manufacturers bypass the more stringent Euro 5 and USA EPA Tier 4 final emissions regulations applied to combustion engines since January 1, 2019. In addition, ematec has deliberately k

Hintergrund: Nach der Montage der 1. beiden Flügel letzte Woche hat man einen Transportschaden am 3. entdeckt. Jetzt hätte man die anderen Beiden wieder demontieren müssen, oder bis zur Beschaffung eines Neuen den Kaputten dennoch montieren, weil der Turm nicht lange mit nur 2 Flügeln stehen darf. Heute am 06.07.2023 wurde der Flügel getauscht. 128 Muttern mit M36 zu lösen dauert etwas 2 Stunden.

Zum Kran: Der Kran hat 132m Hauptausleger plus 12m leichte starre Spitze. https://www.liebherr.com/de/deu/produkte/mobil-und-raupenkrane/raupenkrane/lr-raupenkrane/lr-11000.html

Hinweis: der Ton vor Ort was durch Traktoren, Vogel Gezwitscher und meiner Unterhaltung mit den anderen Zuschauern geprägt. Da der Originalton im Zeitraffer ohnehin nicht geht, habe ich meine Tonkonserve des Liebherr LTM 1300 verwendet. Ich mache aber noch eine LR 11000 Tonspur für das nächste Video.
