摘要

A method and an arrangement for removing and lifting of a slewing ring bearing of a wind turbine after a blade from a rotor hub of the wind turbine is removed, is disclosed. The arrangement and method enables the lowering and lifting of the wind turbine without the need of large and heavy cranes so that the replacement can be carried out cost effectively. The arrangement includes a first pulley mounted at the bottom of the wind turbine, a second pulley mounted inside a rotor hub, a lifting line running over the first pulley, the second pulley and further over a third pulley mounted inside a carrier. The carrier supports the slewing ring bearing during lifting and lowering which is achieved through a coordinated operation of a ground winch, the lifting line and tag lines. Further, rigging equipment is attached to the lowered slewing ring bearing to enable easy transportation.
