Abstract (en)

[origin: WO2010031528A2] The invention relates to a hoisting device for a wind turbine, said device being movable on a support track in a machine housing of the wind turbine. The machine housing is rotatably mounted on a tower and supports a rotor and a drive train. Suitable crane systems are needed to supply the required means and tools to the machine housing for servicing and repair purposes. Up to now, chain hoists have been used for small to medium-sized loads, up to approx. 1 tonne, the hooks of which hoists can be lowered through a hatch in the floor of the machine housing. This allows replacement parts, such as a drive motor for the azimuth bearing to be hoisted from the floor into the machine housing. One disadvantage is that the size of the useful load is limited by the size of the floor hatch. The aim of the invention is to provide an improved hoisting device for a wind turbine and an improved wind turbine, which have none of the disadvantages of prior art. The aim is achieved by the features of main claim 1, wherein the hoisting device for the wind turbine is provided on the support track in a machine housing of the wind turbine. The support track of the hoisting device runs completely within the machine housing and comprises a roller mechanism and a load arm. The load arm and roller mechanism are designed in such a way that the load arm projects through a substantially vertical wall of the machine housing.
