Abstract: A method for erecting a pre-stressed sectionalized and segmented concrete tower for wind power or heliostatic generator or chimney is provided. The method includes the step of providing a plurality of assembling supports and lifting harnesses in order to support to the concrete segments for assembling concrete section from the concrete segments using a small capacity crane, and installing, with a high capacity crane the assembled concrete sections to conform the concrete tower. The lifting harness provides safety scaffolds for personnel during prestressing.
