Lean, Innovative, and Unique Project Solutions
This was Cianbro’s first wind turbine erection project. Not only did Cianbro design and fabricate the transportation vehicles, brackets, and rigging, the Cianbro team also transported the wind turbine components and Liebherr 1400 construction crane up a 2.5 mile slope to the mountain summit, with grades as steep as 30%.
