Abstract
The invention relates to a rotor blade attachment (), in particular of a wind power plant (), for the connection of a rotor blade () with an attachment device (), including a transverse pin (') and a connecting device (), which can be brought together to establish an operative connection, wherein the connecting device () defines a longitudinal axis. The rotor blade attachment () is characterized in that the transverse pin (′) in the direction of the longitudinal axis of the connecting device has a higher bending stiffness than transversally to the longitudinal axis (). An alternative rotor blade attachment () is characterized in that the transverse pins (′) are arranged in at least two rows (), wherein at least a first row () is arranged closer to the blade-root-side end () of the rotor blade () than at least a second row (). Another rotor blade attachment () is characterized in that the transverse pin (′) is completely encapsulated by the rotor blade ().
