Abstract
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.
