  "abstract": "A base (100) for supporting a portable crane for handling components of a wind turbine. The base (100) is mountable on the wind turbine, and configured to be switched between a first configuration and a second configuration. In the first configuration the base (100) is configured for being supported by a main bearing of the wind turbine. In the second configuration the base (100) is configured for being supported by a bed plate of a nacelle of the wind turbine. The base is configured for supporting the portable crane while switching between the first configuration and the second configuration. A method for removing a main bearing of a wind turbine is also disclosed.",
