Development of Rhombus Hanging Basket Walking Track Robot for Cantilever Casting Construction in Bridges

For enhancing the efficiency of cantilever casting construction in a bridge, novel rhombus traveling track for hanging basket was developed and optimized. The business-oriented software called MIDAS applied to analyze mechanical properties with full load control load. strength distortion walking mechanism are within specified range when maximum beam unit internal force is 149.69 MPa, which less than allowable stress steel 175 Mpa, anti-overturning safety factor 2.5, meets requirements. Through comparative analysis key components finite element calculation, it found that there about 30% redundancy structure performance. Therefore, further optimization each carried out, front elevation main truss 20° achieved. It obtained best performance all aspects.
