  • Patent number: 8782966
    Abstract: Disclosed are apparatus and corresponding methodology for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Different types of concrete are used between upper and lower sections of the stacked cylinders. The lower section uses reinforced concrete while the upper section used ultra high performance fiber reinforced concrete.

  • Publication number: 20140102039
    Abstract: A method of erecting, and a method of servicing or dismantling, a wind energy plant with a hub height of at least 140 meters makes provision that a heavy-duty lifting device is temporarily disposed on a tower top for any installing, exchanging, or disassembling purposes, and subsequently is dismantled immediately, with all these operations being carried out without using an external crane. A light-duty lifting device attached to the tower serves for erecting the tower, so that no external large-scale cranes are required. For disassembling or exchanging the large components, an auxiliary lifting device is able to transport the heavy-duty lifting device to the top of the tower and is also capable of lowering the heavy-duty lifting device from there.
