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.
