A tower section and a wind generating set. The tower section comprises a tower section body and hoisting lugs, wherein through holes are provided in the sidewall of the tower section body, and an inner cavity of the tower section is communicated with the outside by means of the through holes; the hoisting lugs are provided in the through holes, are movable along central lines of the through holes, and can move between a first position where the hoisting lugs extend out of the tower section body and a second position where the hoisting lugs are retracted to the tower section body, so as to hoist the tower section. Because the hoisting lugs can selectively extend out, a tower hoist is not needed to be connected to a flange in a tower section hoisting process, and the hoist is mounted on the hoisting lugs.

A blade transport holder for supporting multiple blades is provided according to the present application. The blade transport holder includes a first support assembly and a second support assembly. The first support assembly includes a first support frame and a first support member rotatably arranged at the first support frame, and the first support member is configured to fix root portions of the multiple blades; the second support assembly includes a second support frame and a second support member rotatably arranged at the second support frame, the second support member faces the first support member, and the second support member is configured to fix tip portions of the multiple blades. With the blade transport holder according to the present application, multiple blades can be transported at one time by a single blade transport holder.

Blade transport holder

A rotor rotating device includes at least two rotating units; a movable end of a telescoping cylinder in each rotating unit is provided with a pin; the pin is releasably secured on a rotor. A control method for the rotor rotating device includes: dividing the at least two rotating units into two groups; first removing pins of a first group of rotating units from the rotor, and then re-securing the pins at another positions on the rotor; and after the pins of all the rotating units are re-secured, changing the state of the telescoping cylinders of all the rotating units, and driving the rotor to turn relative to a machine base. In this way, all the rotating units are sequentially unlocked, moved to a next working station, and re-locked on the rotor. A control device, and a rotor rotating system are further provided.
