摘要:
An advanced system for the installation of wire-climbing lifting devices on hollow towers is presented. This system allows two positions easily alternated by the operator of the installation: a resting position, in which the wires (5) are hidden inside the tower (1) and a maintaining position in which wires (5) are safely set up outside the tower (1) to allow a lifting device climbing on them. At the resting position the wire terminals are at ground level so the operators are able to inspect the conditions of them before their use and the safety of the system is improved.

The invention relates to a tower (1) for a wind power plant, having a lower part (1.1) in the form of a lattice tower or trussed tower having at least two corner legs, and an upper part (1.2) in the form of a tubular tower substantially round in cross-section, wherein each corner leg (1.10) is composed of a plurality of steel tube profiles (1.11, 1.12) connected to one another in the longitudinal direction. In order to achieve good transportability and simplified assembly of the components of such a tower, the invention provides a modular tower concept. According to the invention, each corner leg (1.10) is composed of at least three steel tube profiles (1.11, 1.12) which are furnished with perforated flanges (1.13) for receiving bolts, wherein the corner legs (1.10) are connected to one another by struts (1.15) and/or tie bars (1.17) connected at the flanges (1.13), and wherein the steel tube profiles (1.11, 1.12) of each corner leg (1.10) are spiral seam-welded steel tube profiles.

The present invention is directed to a system and method for transmitting and distributing electricity in which a transmission tower is adapted to include a natural power device for converting wind or solar energy into electricity. The natural power device is electrically connected as a source to at least one or more transmission lines connected to the transmission tower, in order to supply the converted electricity to a distribution grid. A wind turbine and/or a solar panel may be implemented as the natural power device.

The present invention concerns a method of transporting a tower (31, 111) of a wind turbine (100) in an upright position to an assembly site of the wind turbine (100), whereby the tower (31, 111) is equipped with a strake set (103) comprising a number of strakes (101) positioned to lead from a top (T) of the tower (31, 111) in the upright position down towards a bottom (B) of the tower (31, 111), at least one of the strakes (101) being realized as a detachable strake (101). The invention also concerns a strake set (103).
摘要:
A transition element between a jacket having four legs and a tower where the lower portion of the tower is fixed to a torsion plate that is connected to an upper portion of the legs. A brace extends from each leg. Each brace includes a strut. The strut has a first end portion and a second end portion. The strut is fixed to the upper portion of each leg and a plate that is fixed to the tower at a contact portion above the torsion plate. The planar plate is fixed to the tower in the circumferential direction and has a common axis of symmetry with the strut. The plate is fixed to the first end portion of the strut.
