Measure the elevation before installing the hanger, then start tensioning the hanger. The tensioning end of the hanger is set at the upper end of the arch rib, and jacks are used to tension in batches, stages, synchronization, symmetry, and circulation to ensure that the force of each hanger cable is equal to avoid distortion of the local arch rib.

The tensioning cable force of the hangers should be strictly monitored, and attention should be paid to timely observation of changes in the bridge deck elevation. The final bridge cable force of the hangers should be consistent with the design cable force.
