Abstract: The invention relates to a method for forming a connection between two pipe segments of different widths, preferably of a tower-like structure, in particular of a wind turbine. In order to be able to connect pipe segments of different widths more easily, reliably and cost-effectively to one another, it is provided that the wider pipe segment is pushed with one end partially over an end of the narrower pipe segment , that the pipe segments are positioned apart from one another by forming an annular gap between the pipe segments, that in the annular gap between the two pipe segments a separating layer extending in the longitudinal direction of the pipe segments and/or in the radial direction is provided, that the annular gap adjacent to the separating layer and at least one side of the separating layer is at least partially cast with a casting compound, that during the hardening of the casting compound the casting compound forms a firm connection on one side of the separating layer with only one of the pipe segments and/or the casting compound forms a firm connection on the other side of the casting compound , only with the other pipe segment and that the pipe segments after the hardening of the casting compound are separated again along the separating layer with the assigned separate connecting elements in particular formed by the hardened casting compound.

Abstract: An assembly, installation package and method for installing a wind turbine tower. The assembly (139) comprises an installation unit (114) having unit guides (140), each configured to engage a corresponding engagement guide (130) adjacent to an upper inner edge of the tower section (110) to guide the assembly while it is lowered into the tower section. The assembly also includes a yoke (136) releasably connected to the installation unit and comprising yoke guides (146), each configured to engage a corresponding engagement guide (130) adjacent to the upper inner edge of the tower section to guide the assembly while it is lowered into the tower section (110). The assembly (139) is configured such that at least one of the unit guides (140) and/or the yoke guides (146) is or are substantially continuously engaged with the engagement guides (130) from when the assembly (139) enters the tower section (110) until the assembly reaches its installation position within the tower section.

Abstract: Hoists, platforms and davits are described as well as methods of securing same to telecommunication and other towers. The hoists, platforms and davits may be secured to the towers on a temporary basis using clamps. The clamps may include brackets and cables. The cables may be attached to the brackets, may wrap around the outer surface/perimeter of the tower pole/leg and may use tension to keep the bracket in place.

Abstract: 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.

Abstract: A device that includes pier caps. Each pier cap is configured to couple to a pole that is at least partially embedded below a surface of a ground. The device further includes threaded rods coupled with the pier caps. The device further includes an assembly frame that includes a base plate and coupling arms. The base plate includes a first plurality of openings that are configured to interface with a structure that is installed onto the base plate. The first plurality of openings are configured to allow a position of the structure to be adjusted radially about the base plate. Each coupling arm includes a second plurality of openings that are configured to allow a position of the assembly frame to be adjusted along a horizontal plane. Each coupling arm is coupled to a threaded rod and a position for each coupling arm is adjustable vertically along the threaded rod.

Abstract: A method of manufacturing precast concrete segments destined to form all or part of a tower (2), the segments being destined to be superimposed within the tower.
The method comprises, for at least a first segment and a second segment destined to be adjacent in the tower, the first segment being destined to be located beneath the second segment, forming said first and second segments using at least one mould comprising a first portion (Ti) and a second portion (Bi) respectively configured to define all or part of an upper face, respectively a lower face of the segment formed therein, the first portion of the mould used for forming the first segment and the second portion (Bi) of the mould (Mi) used for forming the second segment exhibiting respective geometries of complementary shapes.
