The invention relates to a system and a method for monitoring a flange connection of a wind turbine, and to a corresponding wind turbine. According to the invention, one or more monitoring bodies () are mounted on one or more bolt nuts () and/or bolt heads of at least one flange connection of a wind turbine, and a circuit of the monitoring bodies () is produced with connecting cables () such that, upon rotation of a slackening bolt nut () or of a bolt head of a slackening bolt and of the monitoring body () mounted thereon, at least one connecting cable () connected to the concomitantly rotating monitoring body () becomes detached, owing to increasing tensile stress on the connecting cable (), a fault in the flange connection being signaled upon slackening of a bolt nut () or bolt.

The invention relates to a device for mounting and/or dismantling a component (), in particular a rotor blade of a wind turbine () comprising a tower head (). Said device comprises at least one guide element () that stretches between the tower head () and the ground () and has at least one supporting device () that is essentially fixed in the air, supporting at least a partial load of the weight of the component () during the transport of the latter () between the ground () and the wind turbine (). At least one guy () leads from the supporting device () to the component (), whereby the length of said guy between the supporting device () and the component () can be modified.

A multi-stage gear box () of a wind power plant, wherein the gear box () includes a gear box housing (). The gear box () includes at least one access opening for the insertion of a work instrument into the gear box housing () or respectively into the interior of the gear box housing () is provided on the outside of the gear box housing () and in that at least one guiding device () is provided for the work instrument inside the gear box housing () so that the work instrument is moveable and/or positionable within the guiding device (). Parts of the gear box () in the gear box housing () are checked and/or worked by a work instrument inserted or arranged or arrangeable in the guiding device ().
