Balanced cantilever construction is a rapid, cost-effective construction method for segmental bridges, especially considering the complex terrain and where a bridge has few spans which range from 50 to 250 M.

Balanced cantilever construction starts from the top of a pier, with the segment normally fixed to the pier either permanently or temporarily during the construction. In segmental balanced cantilever construction, the precast segments are transported to the bridge and placed and held at the right position before pre-tensioning back to the rest of the bridge. Stability of the end cantilever is maintained by using temporary pier supports as the end span is begun.

Generally speaking, when we mention Balanced cantilever construction method, form traveller, launching gantry, and segmental lifter all refer to this method. Contractors could Choose different equipment according to the construction cycles, cost and bridge situation.
