900 t隧道型运梁车是为适应我国铁路客运专线施工的新形势而研制的新型运梁车,与普通型运梁车不同之处是其驮运高度低,能满足驮运整孔箱梁通过隧道的要求。该车可以在不切掉翼缘的情况下,驮运900t整孔箱梁通过隧道,能够降低工人的劳动强度,提高施工效率和工程质量,而且可以同常规架桥机配合完成架梁作业,现已完成运输箱梁200多孔。实际应用表明,该机驮运整孔箱梁过隧道作业,通过性能良好、顺畅。介绍900t隧道型运梁车的主要技术参数及结构特点。
The 900 t tunnel girder car is a new girder girder car developed to meet the new situation of the construction of China’s railway passenger dedicated line. The difference with the ordinary girder car is that the bow girder height is low, Requirements for tunneling. The car can not cut off the flange case, carrying 900t box hole beam through the tunnel, can reduce the labor intensity and improve construction efficiency and project quality, but also with the conventional bridge machine to complete the beam work, Has completed the transport box 200 porous. The practical application shows that the machine packs the entire box girder tunneling work through the good performance, smooth. The main technical parameters and structural features of 900t tunnel girder are introduced.
