The calculation of the load-bearing cable should be more accurate, because the span of cable crane used in bridges construction becomes larger and larger. For the most frequently used setting up scheme of cable cranes used in the largerspan bridge construction, the tension force formulation of load-bearing cable is deduced with the eonsideration of all loadbearing cables as a whole, and the way to calculate the main design parameters of load-bearing cable is put forward. A case study of cable crane with tower is carried out on Beipanjiang Bridge of highway from Shanghai to Ruili in Yunan. Thro...
