A tower for a wind turbine may include an upper tower portion and a lower tower portion. The upper tower portion may include a tubular tower, and the lower tower portion may include a lattice tower. To improve ergonomics and work safety and make it possible to obtain a structural design with optimized forces, the lower tower portion may include a central tube positioned centrally within the lattice tower. Further, the central tube may have a smaller diameter, at least in certain portions, than at least part of the tubular tower of the upper tower portion. The tower may also include a transition piece between the upper tower portion and the lower tower portion. The transition piece may join the tubular tower of the upper tower portion and the central tube of the lower tower portion.

A wind turbine tower (14) is supported on a transition piece (18) that connects the tower (14) to a foundation and that defines a space (28) beneath the lower end of the tower (14). Electronic components positioned within a removable module (24) in the lower portion of a wind turbine tower may be removed through a lower end of the tower for service or replacement.

This application relates to tower segment handling methods and apparatus and, in particular, to methods and apparatus for handling segments of steel wind turbine towers. The wind turbine tower comprises a plurality of cylindrical vertical tower sections, which in the finished tower are mounted on top of one another. The vertical section of the tower has a longitudinal axis and comprises a plurality of wind turbine tower segments, the tower segments have vertical and horizontal edges and combine to form a complete vertical tower section by joining along their vertical edges. Adjacent vertical tower sections are joined to each other along the horizontal edges of the wind turbine tower segments. The tower segments are combined into a tower section using a flat roller bed on which the segments can be assembled. A method of assembling a tower section is discussed.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

A strut linkage for a steel construction may involve a tower of a wind turbine and/or a corner post of a lattice tower. In order that high forces can be removed via the strut linkage without causing increased stress concentrations, excessive use of material, and/or an excessive structural outlay, a plate element is provided for arranging between, preferably load-bearing, steel construction components. At least one connection element, which may be connected to the plate element, may be utilized to fasten at least one strut and/or guy of the steel construction to the steel construction components via the plate element.

A technique for reinforcing a telecommunication tower includes attaching a temporary structure to a vertical portion of the tower, transferring antenna equipment from the vertical portion of the tower to the temporary structure, and reinforcing the vertical portion of the tower while the transferred antenna equipment continues to operate. Once the vertical portion of the tower has been reinforced, the antenna equipment is transferred from the temporary structure back to the vertical portion of the tower. The temporary structure may then be moved to any other vertical portion of the tower, where the above acts may be repeated.

The present invention discloses a transition piece (10) for connecting a first component (20) having at least three columns (21) to a tower-shaped second component (30), wherein the transition piece (10) can be arranged between the first component (20) and the second component (30) and comprises a connection device for connecting the second component 30. The transition piece (10) is characterized in that it has at least three curved elements (11), the respective legs (13) of which are connectable at least indirectly to the first component (20). Each curved element (11) can be brought into direct contact with the second component (30) by means of convex end sections (14) arranged between the respective legs (13). In this way, the convex end sections (14) of the curved elements (11) form a receiving region (15) of the transition piece (11) and the second component (30) can be inserted into this receiving region.
