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: The elongated box frame structure of the present invention comprises a plurality of frame segments attached to at least one end piece. Preferably, two end pieces are attached, one at each end of the plurality of frame segments. The plurality of frame segments are attached to the end piece such that a column-like structure is formed. The inner space defined within the frame segments is substantially free of webbing. Instead, structural strength and stability is achieved by the attached end pieces. The end pieces of one elongated box frame structure are capable of removably connecting with the end piece of other similar elongated box frame structures to achieve varying framing heights and other dynamic configurations.

Abstract: A hoisting device for big loads, comprising at least one hoisting mast, a foot arranged on the underside and hoisting means connected at least to the top, wherein the hoisting device is assembled from mast parts which are mutually connectable by means of connecting means and the largest of which has dimensions which do not exceed those of a usual container, and wherein each mast part is constructed as a framework structure consisting of angle bars and cross bars mutually connecting the angle bars, wherein the angle bars consist of two parts with a set-square-shaped cross section of different dimensions and wherein the outer ends of the legs of the smaller lie against the legs of the larger and the larger part lies on the outer periphery of the mast part, so that mast parts are provided of the greatest possible strength and stiffness within the dimensions of typical containers.

Abstract: A tower support structure for supporting communications equipment or other types of equipment above the ground is provided. The structure includes a foundation, a tower having a number of tower sections is supported by the foundation. The tower includes main bracing systems and sub-bracing systems extending between the tower columns. A cable support structure is anchored to the ground and is also connected to the tower.

Abstract: A long-span structure formed in-situ and extending between supporting structures includes at least two form supports extending between the supporting structures. Each end of the form support includes a bearing plate coupled to the adjacent supporting structure. A plurality of form hangers frictionally engage the form supports, wherein each form hanger has upwardly extending hooks. A beam form is carried by the plurality of form hangers and extends the length of each form support. Each beam form has opposed side walls connected by a bottom to form a cavity. Each sidewall has a downwardly extending hook mating with the upwardly extending hooks. A deck is supported by the beam forms with the cavities remaining open. The concrete is receivable at least in the cavities to form the long-span structure.
