ABSTRACT:
A wind power plant comprising a tower carrying a power system including a power house and vanes rotatable by the wind. The tower has a lower natural frequency of vibration between the lower and higher critical frequencies of vibration of the power system, and the tower has a higher natural frequency of vibration above the higher critical frequency of vibration of the power system. A ring surrounds and is disconnectably attached to the tower, and guy wires extend from the ring to the ground. The power system is assembled on the ground and so that it surrounds the tower, and the power system is then elevated, together with the ring, along the tower. Elevation may be accomplished with cables and a winch. Alternatively, a thread-like ledge may surround the tower and the power house may carry means for engaging and moving along the ledge to elevate and lower the power house.
