Rotor and nacelle disassembling device for windmill, has blocking units with plates equipped with holes that are aligned one to another when support come across top of mast, where units, holes and rods allows assembly in top of mast

摘要

The device has a support (8) sliding along a mast (1) on parallel guide rails (9, 10) allowing a crane-support assembly (6) to move along the mast by a lifting unit. The assembly is connected to a hoist (11) of the unit by a cable (12) passing on a pulley. The cable is passed on another pulley when the hoist is placed outside. Blocking units has plates projecting from periphery of the support. The plates are equipped with holes aligned one to another when the support come across mast`s top to receive locking rods. The blocking units, holes and the rods allows the assembly in the mast`s top. An independent claim is also included for a method for rapidly disassembling of a rotor and a nacelle of a mast of a windmill.
