The invention relates to a device (100), a system (10) and a method for modifying the cross section of a tower section (1) of a wind turbine, wherein the tower section comprises a flange (4) located at an end (3) of the tower section having a plurality of through holes (5) spaced around its circumference for securing said tower section to another wind turbine section. The method comprises securing tensioning mechanism (14) to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed; and applying a tensile force between said pair of holes in the flange of the tower section.

A repair device for a pipe repair device comprising at least one body extending along a main axis between a first end and a second end and telescopically expandable, in a controlled manner, along the main axis so as to bring the ends closer or further apart from each other, a first contact plate connected to the body at the first end and extending along a first plane curved transversal to the main axis, a second contact plate connected to the body at the second end and extending along a second plane curved transversal to the main axis, wherein the plates are removably constrained to the body in such a way that they can be replaced.

A robot for straightening double thin-wall section pipe with undesirably shaped cavities, includes two racks, a positioning component, a shaping component and a driving component. In operation, the double thin-wall section pipe is put in the positioning component, and the shaping component is used for shaping the pipe by the driving of the driving component. The robot improves the working efficiency, and is not only compact in structure design, stable in movement, precise in positioning and reliable in locking, but also convenient for disassembly and maintenance.
