Pioneering innovation

The new traverse systems RBC (for Rotor Blade Clamp) and the double version RBC-D now overshadow everything that has come before. As the world's first rotor blade lifter, they are able to grip all blade shapes available on the market without having to do any modification work - including future ones. This is made possible by an automatically adaptive blade support plate, by which it is possible for the lifter itself to precisely adapt to every rotor blade shape. A patent has been applied for this technology. The new rotor blade lifters are able to grip and handle blade weights of up to 40 tons. The double version RBC-D is able to handle blade weights of up to 35 tons. Another extraordinary feature of the RBC series is its tilting angle of ± 30 degrees. The new type of rotor blade lifters can be universally used in the wind power industry - both onshore and offshore. With a slope height of just 3.5 metres, the RBC series facilitates crane management, especially with regard to the constantly increasing hub heights of wind turbines.

Particularly gentle to the rotor blade

The "D" in RBC-D stands for "double" and means that in addition to the lower telescope gripper, also the upper gripper is equipped with fourteen hydraulically driven and gimballed grip pads. These grip pads adapt to the individual blade shape like fingers of a hand. If is not just a gripping in the classic sense, but rather a gentle but safe clasping of the rotor blade. The special feature: Thanks to a very homogeneous load distribution with a contact area of approx. 10 m², the blade stays safe. This large contact area makes it possible to tilt the rotor blade ± 30 degrees without the need of an additional safety rope
