Abstract: An electrical power generator for a wind turbine comprising: a generator housing, a stator at a radially outward position and a rotor in a radially inward position, wherein the rotor comprises a cylindrical ring structure arranged about a rotational axis, R, and defining a central hollow portion. The electrical power generator further comprises a rotor shroud attached to the generator housing and which extends about the rotational axis, R, wherein the rotor shroud includes a dome portion that extends into the central hollow portion of the rotor so as to protect the cylindrical ring structure of the rotor. Advantageously, the rotor shroud provides a tunnel-like surface that extends into the central hollow portion of the generator so as to prevent objects such as tools from contacting components of the rotor. The invention also relates to a method for 15 assembling such an electrical power generator with a rotor shroud.

Abstract: A transportation arrangement (10) includes a truck (32) and a trailer (34) operatively coupled to each other for hauling a blade. A separate dolly vehicle (36) is coupled with the truck and trailer. The transportation arrangement (10) also includes a blade (24) extending between a root end (38) and a tip end (40), wherein a root region (25) of the blade (24) proximate the root end (38) is supported on one of the trailer (34) or dolly vehicle (36) so as to span between the trailer and dolly vehicle. The root region (25) of the blade is pivotable relative to the support element about a first vertical axis (V1) spaced apart from the root end (38). The tip region (29) of the blade (24) proximate the tip end (40) is pivotable relative to the support element about a second vertical axis (V2). At least a portion of the root region (25) and at least a portion of the tip region (29) are configured to extend laterally away from the side of the transportation arrangement when the trailer (34) and dolly vehicle (36) are longitudinally offset from each other.
