Embodiment Construction
[0021] As described above, the present invention relates to solutions and methods for configuring a wind turbine hub for transportation such that the dimensional envelope of the hub is reduced along at least one axis. In the known art, the outer dimensions of the hub are fixed during manufacture. In order to be transported to where the hub is to be installed, the hub must be loaded onto a trailer and transported by road for at least a certain distance. Public roads often have width restrictions to ensure the safety of other road users, and height restrictions to ensure that loads are not compromised by low bridges, gantry and other intersecting road structures along the route. For this reason, therefore, these width and height constraints are design and engineering constraints for wind turbine hubs. Accordingly, the present invention provides a device by which the outer dimensions of the hub can be reduced prior to transport, after which the hub can be reconfigured to its in-...
