Form travelers with fore-fulcra is a commonly used machinery equipment during the cantilever casting construction of cable-stayed bridges with concrete girders. Taking the cable-stayed bridge of Jin'an Jianbang Yellow River highway bridge as an example,from the perspective of construction control,several aspects are discussed including types of form travelers with fore-fulcra, simulation of construction control, determination of the forces of the anchoring system ,form travelers adjustment, determination of the tension number and tensile force of the cables, and the deformation error analysis of form travelers with fore-fulcra.
