The negative bending moment tensioned suspension platform, designed and manufactured by the An'ersi Xiangli project department, is being promoted for use along the entire Xiangli line.

Recently, the bridge negative bending moment tensioning cradle designed and manufactured by the company's Xiangli project department has been promoted for use throughout the Xiangli Expressway construction site.

In the construction of the Xiangli Expressway, the construction under the bridge joints is high-altitude work, which poses a significant safety risk. At the command center's request, after research by the company's Xiangli project department, an integrated folding cradle solution was proposed. The biggest feature of this cradle is that when folded, its width is only 35 centimeters, and when opened, it can form a space of 1.2 meters × 0.9 meters × 2 meters, ensuring the safety of the workers while allowing a two-person cradle to be lowered from a bridge joint only 60 centimeters wide, ensuring the safe construction of negative bending moment steel strand tensioning.

After passing the review by the command center, the supervisory unit, and relevant experts from various sections of Xiangli, the project department worked overtime to manufacture them. As of press time, 19 cradles for the middle beams and 22 cradles for the side beams required for the entire section have been manufactured and put into use in various sections.
