Lifting and positioning two 2,000 ton cable-stayed bridge pylons into place. To prevent counter-balance issues, it was critical to erect both pylon sections simultaneously and within a very tight tolerance.

Lifting and positioning two 2,000 ton cable-stayed bridge pylons into place. To prevent counter-balance issues, it was critical to erect both pylon sections simultaneously and within a very tight tolerance. Any counter-balance issues would have created a lopsided load and put undue stress on the center pillar. The lack of a good footprint and the approximately 100 meter lifting height made the lift almost impossible for two cranes or another lifting solution. The need to lift from the central point of the structure required a high capacity lifting solution that could raise both sections simultaneously from a central point.
