摘要： A system for assembling a tower for a wind generator having a succession of subsections (Si). The system including: a plurality of lifting legs, a lifting structure vertically movable on the lifting legs, the lifting structure including a rigid lifting frame for holding the tower under assembly, the lifting frame including load transfer members and the lifting structure including self-climbing mechanisms interacting between the load transfer members and the lifting legs for elevating or lowering the lifting structure, and at least a first set of gripping arms movable relative to the lifting frame between a retracted configuration and a gripping configuration.

摘要： A contribution is made to the assembly of a wind turbine intended to comprise, in a final assembly condition, a tower (2) surmounted by a nacelle (4) cooperating with a rotor (5) receiving a plurality of blades (3a-3c). To this end, a temporary association is made between at least some blades from said plurality of blades and the tower, so that said blades extend substantially in the longitudinal direction of the tower.

摘要： A system for holding a tubular sleeve (2) in a receiving structure during setting of a cement or other binder introduced in a fluid state between the sleeve (2) and the receiving structure, comprising:—at least one expandable structure (4) mounted on the sleeve (2), deformable from an inactive configuration allowing insertion of the sleeve (2) in the receiving structure to an active configuration immobilizing the sleeve (2) in the receiving structure,—at least one corresponding tool to be inserted in the sleeve (2), configured for acting on the expandable structure (4) to cause it to pass from the inactive configuration to the active configuration.
