Abstract: A machine support for a wind power installation, in particular a gearless wind power installation, wherein the machine support is designed to be rotated about a tower axis by means of an azimuth drive, and has a supporting structure which has a first mechanical interface for connecting the machine support indirectly or directly to an azimuth bearing and a second mechanical interface for assembling a generator or an axle journal on the machine support. It is proposed in particular that the supporting structure has one or a plurality of lateral through openings as access to the azimuth drive and/or the azimuth bearing.

Abstract: A wind power plant comprising a first structural element, a second structural element, a bearing assembly by means of which the first structural element is rotatably mounted on the second structural element, a first flange connection between the first structural element and the bearing assembly, a second flange connection between the second structural element and the bearing assembly, and at least one drive, held by a support structure for rotating the first structural element relative to the second structural element. The support structure is formed as a plate and is arranged at one of the flange connections.

Abstract: A wind turbine is provided, having a nacelle, and having a rotor that has at least two rotor blades. The rotor blades each have a rotor blade root, at least one metallic conductor, for conducting a lightning strike, and connected thereto, provided in the region of a rotor blade root, have a conducting ring. In addition, a lightning protection unit is fastened to the non-rotating part of the nacelle in such a manner that the lightning protection unit lies on the ring. The lightning protection unit has two rollers and a lightning rod, a free end of the lightning rod being separated from an outer end of the rollers by a distance that defines a spark gap.
