Abstract: A main shaft fixture for fixing a main shaft on a wind turbine during installation and repair work on heavy parts of the wind turbine nacelle, in the case where the fixture is formed of several sections for mounting on stable structural parts in the nacelle, including the nacelle's bottom frame. The main shaft fixture has adjustable pressure mandrels with tap shoes, which cause the fixture to be usable regardless of the turbine main shaft geometry, such that it can be mounted without fixing the rotor. The main shaft fixture also has facilities for mounting of a lightweight crane and a self-hoisting crane with a ground-based winch, respectively, as well as a rotor lock which, in combination with actuators of the main shaft fixture, enables the main shaft and the main shaft bearing to be sufficiently displaced vertically from its bearing in the nacelle to service or replace the bearing.

Abstract: A method for automatic control of the position of a burden suspended in a main wire of a crane, where the burden is connected with at least two tag lines which respectively is connected to a number of winches. The control of the position and rotation of the burden is performed by actuators on the respective winches which perform ease off/tightening of the respective tag lines from signals of at least tone measuring unit with signal transmitter located on the burden measuring angles. A central monitoring- and control unit performs control of rotation and position of the burden by multiple transmitting of compensatory control signals to relevant actuators for tag lines and the crane main wire. Guiding and control of the position of the burden is possible even when subject external random impacts, as wind and sea. Further the method is useable in positioning the burden in correct mounting position.

Abstract translation: 一种用于自动控制悬挂在起重机的主线中的负担位置的方法，其中所述负载与分别连接到多个绞盘的至少两个标签线连接。 负载的位置和旋转的控制由相应绞盘上的致动器执行，该致动器使得位于负荷测量角上的信号发射机的至少音调测量单元的信号执行各个标签线的松脱/紧固。 中央监测和控制单元通过将补偿控制信号多次发送到标签线和起重机主线的相关执行器来执行对负载的旋转和位置的控制。 即使受到外部随机影响，如风和海，也可以指导和控制负担的位置。 此外，该方法可用于将负担定位在正确的安装位置。
