Abstract: A turner gear assembly (52) for turning an unbalanced rotor of a wind turbine (10) having a drivetrain (30). The turner gear assembly (52) includes a turner gear (50) configured to couple to the drivetrain (30) and having at least two motors (58a, 58b), and a valve block (78) connectable to the turner gear (50) and having a first flow control valve (106) configured to be in fluid communication with a pump (80) and with the at least two motors (58a, 58b). The first flow control valve (106) is selectively moveable between a first fluid control position (106a) and a second fluid control position (106b). When the first flow control valve (106) is in the first fluid control position (106a), the at least two motors (58a, 58b) operate in parallel and when the first flow control valve (106) is in the second fluid control position (106b), the at least two motors (58a, 58b) operate in series. A method of operating the turner gear assembly is also disclosed.

Abstract: A transportation arrangement (10) includes a dolly and a clamp (20) secured to the dolly (14). The clamp (20) includes a frame (30) having a lower portion (32) coupled to the dolly (14) and an upper portion (34) selectively rotatable relative to the lower portion (32), a saddle (100) positioned on the lower portion of the frame, a jaw (130) movably positioned on the upper portion (34) of the frame (30), and an actuator (150) operatively coupled to the jaw (130) and configured to move the jaw (130) relative to the saddle (100) to apply a clamping force on a blade (16). The actuator (150) is configured to extend the jaw (130) toward the saddle (100) in response to the clamping force being less than or equal to a minimum threshold clamping force, and may be configured to retract the jaw (130) away from the saddle (100) in response to the clamping force being greater than or equal to a maximum threshold clamping force. A method of transporting a blade (16) is also disclosed.
