Abstract: A height adjustable pylon and supporting frame assembly is provided. The frame includes two frame members meeting at a corner with the frame members being generally co-planar and the pylon being urged into the corner so as to extend at generally right angles to a plane including the two frame members. A fastener assembly has two end portions each anchored relative its associated frame member so as to extend transversely to it. The fastener assembly includes an intermediate saddle portion engaging a surface of the pylon that is directed outwardly relative to the corner with the pylon being urged into the corner when the fastener assembly is tightened to engage the pylon and lock it axially relative to the frame members in a selected position. Preferably, the frame members each form two upper and two lower frame members of two trusses. Lower ends of the pylons may support the assembly.

Abstract: A supporting frame includes a truss composed of an upper straight frame member and a parallel lower straight frame member supported at their ends in spaced relationship relative to each other. At least two spans of divergent inclined brace member extend between them with the ends of the brace member spans each being securable to the upper or lower straight frame member by means of a fastener. Limited relative longitudinal movement of the upper and lower straight frame members is permitted before a fastener is secured to fix the positions at which the ends of the brace member spans are attached to the upper and lower straight frame members. In one application two trusses meet at a corner with a pylon being urged in the plane of the supporting frame into a corner between two frame members of each pair of trusses to extend at right angles to the frame.

Abstract: A structural tower for a wind turbine assembly, includes along at least a base section: a plurality of peripheral sections extending peripherally of a central section.

Abstract: A tower includes an outer portion forming an outer covering for the wind turbine tower and an inner portion disposed within the outer portion. The inner portion includes a preassembled power module including an upwardly extending support and electrical components that extend outwardly beyond the upwardly extending support and guide supports coupled at a first end to the upwardly extending supports and extending outwardly beyond the electrical components.

Abstract: A deployable truss is formed from a plurality of column members connected at their ends where at least some of the column members are formed from column assemblies, each including a plurality of strut members that are at least connected to each other at a first and second end of the column assembly. For added rigidity, strut members of a column assembly may be connected to each other between the first and second ends using, for example, a rigidizable resin, a fixed spacer, or a deployable spacer. Connecting strut members between the ends of the column assembly provides mutual bracing to the strut members and decreases the free buckling length of the individual strut members. Spacers are preferably configured to radially space the strut members away from the longitudinal centerline of the column assembly to increase its moment of inertia, and hence its buckling strength.

Abstract: A one-piece, unitary, elongate, tubular light pole. The elongate light pole defines a central axis and is constructed from a filament-wound composite of fiber-reinforced bonding agent and has a wall thickness of less than ¾ inch, and preferably ? inch. The pole is configured and adapted to support a lighting structure thereon without failure of the composite, such that a twenty-foot section of the pole is capable of withstanding a lateral load transverse of the axis of at least 300 pounds without failure of the composite.

Abstract: A guyed tower is used to support wireless communication equipment and/or other types of loads. The guyed tower is fixedly attached to a foundation, and a pole tower is erected within a middle region of the guyed tower. This pole tower is also fixedly attached to the foundation. The pole tower supports the guyed tower by absorbing bending moments that are applied to the guyed tower. Thus, the presence of the pole tower within the middle region of the guyed tower enables the guyed tower to support additional wireless transmission equipment and/or other types of loads.

Abstract: A guyed tower is used to support wireless communication equipment and/or other types of loads. The guyed tower is fixedly attached to a foundation, and a pole tower is erected within a middle region of the guyed tower. This pole tower is fixedly attached both to the foundation and to the guyed tower. Bending moments are transferred from the guyed tower to the pole tower via the collar that is disposed about the guyed tower. Thus, the presence of the pole tower within the middle region of the guyed tower increases the load capacity and stability of the guyed tower.

Abstract: An antenna support for a power transmission tower having a vertically disposed mast extending upwardly through the tower with the antenna support being mounted on the upper end of the mast. The weight of antenna support is transferred to the legs of the tower rather than to the mast through the use of support bracing extending between the elongated pipe and the tower. An antenna platform is mounted on the upper end of the mast with the weight thereof being supported by the elongated pipe. The platform is comprised of three triangular-shaped platform sections having mounting rings at the inner ends thereof which are slipped over the upper end of the mast with the lowermost mounting ring resting upon the upper end of the elongated pipe. The antenna support may be mounted on a cellular transmitting/receiving tower or on a guy-wired mast.
