An apparatus is for performing parts of an operation to install a wind turbine, wherein the wind turbine has a tower, wherein the apparatus has a travelling car for travelling up and down along the tower for the wind turbine, and wherein the travelling car has a movable portion of a deck of the travelling car, wherein the movable portion of the deck is configured to carry an item to be installed as part of the wind turbine to a height for installation of the item and for moving the item substantially horizontally into a position for installation of the item when the travelling car is in a vertical position for installation of said item. Further is disclosed a method of installing at least a part of a wind turbine.

A basketball goal including a lower pole, an upper pole, a backboard and a rim. The lower pole extends from a base and extends with a lower pole hinge adjacent one end of the lower pole. The upper pole includes an upper pole hinge, the upper pole hinge configured to be coupled to the lower pole hinge with a pin to facilitate pivotably coupling the upper pole to the lower pole. The backboard is configured to be coupled to the upper pole, and the rim is configured to be coupled to the backboard. The pivotable coupling between the lower and upper poles is for assisting assembly of the basketball goal with an assembly system such that, upon assembling the basketball goal, the upper pole is fixated in an upright position with the lower pole. Also, a light pole may be assembled with a hinged coupling, similar to the basketball goal.

A pile upending device for large diameter tubular elements includes; an annular base ring for extending along substantially the entire circumference of the tubular element, a central lifting arm for coupling the pile upending device to a hoisting element, which lifting arm is hingeably coupled with the base ring, a number of wedge assemblies disposed along the outside circumference of the base ring for facing the inside surface of the tubular element and frictional engagement with the tubular element.

A ground mounting assembly, system and methods for ground mounting a structure include a plurality of posts, each of which are attached to at least one stabilizing plate. The posts may be at least partially positioned underground, with the connected stabilizing plates being buried to a depth of about 1 foot. Posts in a front portion of the mounting assembly may be connected to an adjacent one of posts in a back portion of the assembly by a cross member.

A material handling tower includes a plurality of vertical column trees forming corners of the tower. Each of the plurality of column trees forms a moment connection including a pair of stub connectors. The stub connectors are perpendicular and extend in a direction of an adjacent column tree. Each stub connector has a proximal end welded to the column tree and a distal end having a connecting plate. The tower has at least one interior platform connecting to the plurality of column trees. Each of the at least one interior platforms has a plurality of outer girders with the outer girders connected to the stub connectors of the moment connections. Each girder has a connecting plate at each of its ends and each of the moment connections is completed by connecting the connecting plate of the stub connectors to the connecting plate of the girder.

A wind turbine tower is made of reinforced concrete with fiber rovings as reinforcements, wherein the fiber rovings are basalt fiber rovings. In one embodiment, the basalt fiber rovings may include, for example, a bundle of multiple parallel oriented basalt fibers forming a thin rope. In one embodiment, the tower is produced in a slip forming process or slip molding process, wherein the basalt fiber rovings are embedded in the concrete during the slip forming process.

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.
