Discussion on Puente Duarte Suspension Bridge Strengthening by H.R. Hobbs and Dr J.M. Roberts

I would like a better explanation of the jacking of the cable saddles on top of the bridge towers. The cable saddles are on sliding bearings and presumably were preset away from their final position deliberately, so that, when the cables were installed, the saddle would move into its direct location. Was the saddle jacking used to control this process or to actually induce stresses into new suspension cables?
