目前,铁路客运专线桥梁多采用双线混凝土箱梁,但干线铁路之间的连接线有时需要采用单线单箱混凝土梁,由中铁大桥局股份有限公司与武汉天捷专用汽车有限公司联合研制的MBEC600型轮胎式运梁车就是专门用于单线桥梁架设的产品,也是应用于我国铁路客运专线的第1台600 t单线运梁车。 At present, double-line concrete box girders are commonly used in the bridges of passenger dedicated railway lines. However, the connecting lines between trunk lines sometimes require the use of single-line single-box concrete beams. MBEC600 jointly developed by China Railway Bridge Bureau Co., Ltd. and Wuhan Tianjie Special Purpose Vehicle Co., Type wheeled girder car is designed for single bridge erection of products, but also applied to China’s railway passenger line of the first 600 t single beam girder.
