JQ700型箱梁架桥机的研究与开发

Research and Development of JQ 700 Type Box-bridge Erecting Machine

鉴于广珠城际铁路箱梁型式多,跨度变化大,曲线半径小,国内现有的900吨箱梁架桥机均不能完成其箱梁架设,本文针对广珠城市铁路箱梁特点,研究开发一种性能先进、功能齐全的新型箱梁架桥机——JQ700型箱梁架桥机。

In Guangzhou-Zhuhai intercity railway, complex box-beam forms, wide range spans and small curve radius make the present 900 ton Box-bridge Erecting Machine cannot work, this article aims at the characteristic of the box-beams in this railway to develop an advanced box-beam bridge erecting machine-JQ 700 Type Box-bridge Erecting Machine.
