According to some implementations a system is provided that includes lifting systems having lifting platforms arranged peripherally around the tower. The lifting platforms cooperate with different connection tools that can be supported on an auxiliary column and thus lift or lower the tower modules. ## Claims ### Claim 1 A system for assembling a wind turbine comprising a nacelle and a tower, the system comprising: a tower foundation configured to support the wind turbine after the assembling, a plurality of spaced-apart lifting systems disposed about the periphery of the tower foundation, each lifting system having a lifting platform that moves vertically upward and downward between upper and lower points, a basic tower module having a top and a bottom, the bottom being configured to rest on the tower foundation, the top being configured to support the nacelle, the basic tower having a first height; and a plurality of upper tower modules that are configured to be sequentially joined together to form the tower, each of the plurality of upper tower modules including a plurality of flanges, at least a majority of the upper tower modules having a second height that is greater than the first height, a plurality of first connectors that is each configured to anchor the plurality of lifting platforms to the nacelle: and a plurality of second connectors different than the plurality of first connectors that is each configured to anchor the plurality of lifting platforms to the flanges of the upper tower modules. ### Claim 2 (depends on 1) The system according to claim 1, wherein the first and second connectors are configured to be removeably attached to the lifting platforms. ### Claim 3 (depends on 1) The system according to claim 1, wherein the second connectors comprise a first part and a second part are configured to be secured to opposite sides of the upper tower module flanges. ### Claim 4 (depends on 1) The system according to claim 1, wherein the upper tower modules each comprise a lattice structure having three or more legs and the number of lifting systems corresponds to the number of legs. ### Claim 5 (depends on 1) The system according to claim 1, wherein the plurality of lifting systems are disposed equidistantly about the tower foundation. ### Claim 6 (depends on 1) The system according to claim 1, wherein the each lifting system is located on a base and is connected to adjacent lifting systems by a joint structure. ### Claim 7 (depends on 1) The system according to claim 1, wherein the upper tower module is a cylindrical structure. ### Claim 8 A system for assembling a wind turbine comprising a nacelle and a tower, the system comprising: a tower foundation configured to support the wind turbine after the assembling, a plurality of spaced-apart lifting systems disposed around the tower foundation, each lifting system having a lifting platform that moves vertically upward and downward between upper and lower points, adjacent lifting platforms support and have disposed between them an elongate horizontal member that spans the distance between the adjacent lifting platforms and is configured to move horizontally inward and outward with respect to the lifting platforms between at least first and second horizontal positions, the second horizontal position being inward of the first horizontal position, when in the first horizontal position the elongate horizontal members are arranged capable of supporting a bottom of the nacelle; and an upper tower module having one or more protruding members that are capable of being supported on the elongate horizontal members when the elongate horizontal members are in the second horizontal position and not the first horizontal position. ### Claim 9 (depends on 8) The system according to claim 8, wherein the plurality of lifting systems are disposed equidistantly about the tower foundation. ### Claim 10 (depends on 8) The system according to claim 8 comprising a plurality of upper tower modules that are configured to be sequentially joined together to form the tower, each of the plurality of upper tower modules having one or more protruding members that are capable of being supported on the elongate horizontal members. ### Claim 11 (depends on 8) The system according to claim 8, wherein the each lifting system is located on a base and is connected to adjacent lifting systems by a joint structure. ### Claim 12 (depends on 8) The system according to claim 8, wherein the upper tower modules comprise a lattice structure having three or more legs. ### Claim 13 (depends on 12) The system according to claim 12, wherein the number of lifting systems corresponds to the number of legs. ### Claim 14 (depends on 8) The system according to claim 8, wherein the upper tower module is a cylindrical structure.
