Lad. Wuhan Hubei 430050 China) Abstract:Because of large size and three direction dip features of arch rib segment in one steel box arch structure the process of turning segments adjusting space angle and so on should be pleted by construction of cable crane.Based on the parison of advantages and disadvantages of existing lifting method sling and auxiliary ponents of cable crane are improved to make them meet the requirement of space angle adjustment and the directly hoisting method suitable for segments of plex spatial position is formed.The designed hanging point and sling are in accordance with relevant specification requirements by checking.
