Abstract

A base for supporting a portable crane for handling components of a wind turbine is described. The base 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 is configured for being supported by a main bearing of the wind turbine to allow the portable crane to lift a gearbox of the wind turbine. In the second configuration the base is configured for being supported by a bed plate of a nacelle of the wind turbine to allow the portable crane to lift the main bearing. 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.
