现在，我只需走过一段和我的脚一样宽的横梁，除了一根悬挂的绳索，什么也靠不住。
Now, all I had to do was walk along a beam that was maybe the width of my foot, with nothing to grasp except that dangling line.
该场地，通过建造大横梁来支持高架公路，横梁的尺寸约为55英尺宽(17米)。高架公路的宽度测量约为90英尺宽(27米)。
The site, which is punctuated with large cross beams that support the elevated roadway, is approximately 55 feet wide (17 meters). The highway above measures 90 feet wide (27 metres).
因而对轨道梁或横梁而言，就遇到了宽支座时梁内力如何计算的新问题。
Therefore for crane grider and crossbeam, have met new problem that how to calculate internal force of the beam while meeting the wide bearing.
