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. Each includes a convex-shaped wall having two longitudinal side edges and an inner framework connected to a respective one of the convex-shaped walls and extending inwardly therein. The inner framework includes spaced-apart transversal structural members connecting the two longitudinal side edges of the convex-shaped walls together and pairs of connecting structural members extending inwardly towards the central section. Each connecting structural member of a pair has a peripheral end connected to a respective one of the longitudinal side edges and an inner end connected to an inner end of a respective one of the connecting structural members of an adjacent one of the peripheral sections to define a structural concavity in the structural tower between adjacent peripheral sections.

A crane system includes a structural truss positioned within a central opening defined by an inside surface of an annular tower, a crane mast connected to an outside surface of the annular tower, and a jib arm connected to the crane mast.

The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.

The present invention relates to a method for manufacturing and assembling a plurality of towers (1) on a wind farm (2), wherein said towers (1) comprise a plurality of precast concrete segments (3) superimposed in height, wherein the method comprises: a) establishing a centralised manufacturing point (6) on the wind farm (2); and b) establishing a plurality of land routes (8) to the definitive location (5) of the towers (1). Advantageously, the method further comprises: c) prefabricating at least one segment (3) of a tower (1); d) positioning the prefabricated segment (2) in a vertical position on a land transport system (9); e) transporting the segment (3) in a vertical position to the definitive location (5) of one of the towers (1), following one of the land routes (8); and f) assembling the segment (3), forming at least one portion of a shaft (4) of a tower (1).

A foundation system for supporting a structure may include a main post, a racking post, and a barb assembly. The main post may include an upper section and a lower section below the upper section. The racking post may be telescopically connected to the upper section of the main post. The barb assembly may be connected to the lower section of the main post. The barb assembly may be configured to move from an unexpanded state to an expanded state, thereby forming a wedge shape at a lower section of the main post.

A convertible carrying case and securement system for a post comprising a case comprising of at least five contiguous panels that form a substantially hexahedral volume, a retractable pull handle on one end of the case, at least one pair of wheels on the distal end of the case at the opposite end of the retractable pull handle, the case having a plurality of straps and/or handles attached to at least one of the outside panel surfaces, wherein the five panels include the case floor, two case side panels, a wheel-side panel closest to the pair of wheels, and a panel parallel to the wheel-side panel but connecting the opposite edges of the side panels, a post comprising at least a stump within the case.

A tower is constructed by erecting an upright former 6; assembling a first section 31 of the tower around the former 6; raising the first tower section 31; assembling a second tower section 32 around the former 6; connecting the first and second tower sections 31, 32, and repeating the steps to add further tower sections. Disassembly is the reverse process. The method of assembly is particularly suitable to mobile towers that are transported on road trailers and may be used with advantage with amusement rides.
