"installed 292 ft. tower under a GE 2.8-127 wind turbine... meters-wide steel plates curled into cylinder... one machine produces towers up to twice as tall and 10X faster... tapered towers with variable wall thickness... joining, rolling, fit-up, welding, and severing of tower section results in continuous production steel tower shells... lightest, lowest-cost, and most structurally optimized... 40-year lifetime... developing mobile factories at turbine sites"
