This paper introduces the concept, technical performance index, structure and construction operation mode of the TTYJ900 type integrated transporter for high-speed railway construction in China. The overall composition, structure, structure and electro-hydraulic configuration of the transport beam girder and the lower guide beam machine which constitute one machine are described in detail. Relative to the split “rack ” three major equipment, analysis and comparison of the advantages and disadvantages of one machine, pointed out that in the construction of high-speed railway in the mountainous area, the aircraft has a good application prospects.
