An antenna assembly and related methods are described. The antenna assembly (1) comprises an extendible mast (2) constructed and arranged so as to be configurable between a coiled form and an extended form. The extended mast (2) is resiliently biased in the form of an elongate tube having a slit along its length. The coiled mast is wound about an axis extending transversely to the longitudinal extent of the mast. An antenna (6) is integrally coupled to the mast such that when extended, the mast supports and positions the antenna, and when coiled, the mast and antenna are coiled together.

Provided is a wind turbine, with at least one hollow construction including at least two longitudinal hollow elements each having a connection interface for connecting the elements either by a slip joint connection or by a flange connection especially a tower including at least two hollow tower elements, wherein at least one connector is guided through the slip joint or flange connection from an inner space to the outer of the wind turbine.

A tower configured to be positioned adjacent to or as a part of existing electrical power utility structures, such as transmission towers, distribution towers, substation structures, etc., includes an outer structure having a lower end configured to be anchored to the ground, and an opposite upper end. An inner structure is positioned within the outer structure and is connected to the outer structure. The inner structure has a lower end configured to be anchored to the ground and an opposite upper end. A mast is movable within the inner structure between a lowered position and a raised position. The mast supports various electronic equipment, such as cellular antenna arrays, remote radio unit (RRU) arrays, microwave antennas, imaging equipment, acoustic sensors, tectonic or motion sensors, thermal sensors, chemical sensors, and/or nuclear sensors.

A method of reinforcing the solid round leg in existing telecom towers (Guyed & Self-Support), it increases the leg resistance in compression (bearing load) over 50%. This type of reinforcing uses the principal and definition of axial force in truss structure by keeping the center of gravity of the new reinforcing members in the same location of the existing solid round leg. This type of reinforcing uses the existing splice pads as a foundation and a platform to build the new reinforcing structure on it. The new reinforcing structure is a replacement of the existing bolting system with new threaded bars and couplers with high strength. The addition of the new threaded bars benefits the overstressed leg, by adding more cross-sectional area to the original solid round leg section.

A method of assembling a structure, such as a wind turbine, is disclosed. The method comprises a step of providing a lifting arrangement comprising a gantry disposed over and/or directly above a rail, and lifting means coupled to the gantry. The method further comprises stacking portions of the structure by: conveyably disposing a first portion of the structure relative to the rail; lifting a second portion of the structure using the lifting means; disposing the first portion underneath the second portion by conveying the first portion along the rail; and lowering the second portion onto the first portion. Also disclosed is a corresponding system for assembling a structure, such as a wind turbine, and corresponding clamping and/or gripping system.

A system and method are used for transporting a plurality of tower sections of a wind turbine on beds of transport devices, such as flat railcars. Supports affix at support locations on beds to accommodate at least one of the tower sections on each of the transport devices. The supports can include bed supports, such as tabs, extending from the beds, and can include cradle supports with slots that engage on the tabs. A circumferential dimension of a cradle is adjusted on each of the supports against which the tower section rests. Each of the tower sections is then supported with at least two of the supports by loading the tower sections on the transport devices. An end of each of the tower sections is then affixed to a flange on at least one of the supports on each of the transport devices.

The present application relates to a tower tube section, a tower frame and a wind power generator set. The tower tube section includes a tower tube section body; a reinforcing assembly including a supporting member connected to the tower tube section body and a plurality of reinforcing cables connected to the supporting member. The plurality of reinforcing cables are arranged at intervals along a circumferential direction of the tower tube section body, and each of the plurality of reinforcing cables extends along an axial direction of the tower tube section body and is apart from a periphery surface of the tower tube section body by a predetermined distance in a radial direction of the tower tube section body. The tower tube section has a strong bearing capacity and low cost, which can meet the power generation benefits of the wind power generator set.
