A system for producing reinforcing cages for wind turbine tower segments, wherein a reinforcing cage has in each case substantially horizontally oriented ring segments and substantially vertically oriented stiffening elements. It is proposed that the system has a receiving area which is adapted so as to receive the preferably inner, substantially horizontally oriented ring segments of the reinforcing cage, a first handling robot for supplying and positioning the stiffening elements, and a second handling robot for connecting the ring elements to the stiffening elements.

A method of manufacturing a metal basket contains: steps of preparing materials, initial welding, bending, and re-welding. In a step of preparing materials, multiple first metal bars, multiple second metal bars, and at least two peripheral bars are provided. In a step of initial welding, the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together so as to produce a grid frame which has a base and multiple surrounding sheets, and the at least two peripheral bars are welded with the multiple surrounding sheets respectively. In a step of bending, the grid frame and the multiple surrounding sheets are bent, such that the multiple surrounding sheets are bent upwardly and are perpendicular to the base. In a step of re-welding, the at least two peripheral bars are welded together.

Systems and methods for producing mesh from wires or rods with programmed changeable steps for the longitudinal and transverse wires. The longitudinal wires (1) and the transverse wires (12) may be fed from coils or be precut. The longitudinal wires are fed in receptacles (2) on carriers (3) with the carriers being found on prefeeder carrier (4), a feeder carrier (6) with grippers (7) transports them towards the welding heads (10) and the produced mesh (20) is received by a mesh carrier (14). The carriers (3) with the receptacles (2) for the longitudinal wires on the prefeeder carrier (4), the grippers for the longitudinal wires (7) at the feeder carrier (6) and the welding heads (10) are displaced in the direction of the transverse wire without restrictions, generally in an unrestricted fashion, so as to correspond to the longitudinal wires being subjected to welding. The transverse wires are fed towards the welding heads to be welded with the longitudinal wires. The machine produces meshes with openings, grouping the longitudinal wires in groups and feeding the groups of longitudinal wires towards the welding heads, adjusting the position of the related mechanisms to the position of the longitudinal wires.
