Tall wind towers can be erected using a mobile tilting frame comprising a major gin pole and a minor gin pole having a longitudinal axis. The tilting frame has a support cable connecting the major/minor gin poles. The minor gin pole can pivot relative to the major gin pole so that the longitudinal axis of the minor gin pole can be perpendicular to the longitudinal axis of the major gin pole.
