The Study On 900T-Grade Guide Girder Non-Moving Lifting Bridge Beam Erection Machine

Railway is the important foundational facilities in a country, which possesses the significant place and leads the backbone effects on the synthetic transportation system. The capability of the main line is still seriously in our country at present, and most of the railways are passenger-cargo mixed traffic lines, except the Qin-Shen dedicated passenger line. It is impossible to meet the running technical requirement to both high speed passenger train and heavy-haul freight train at the same time. The higher demand of passenger-cargo transported can't be satisfied also. Building the dedicated passenger line and making passenger transport and freight transport be separated in the busiest trunk lines, can sharply raise the capability of railway transportation. The transfer of passenger trains running in the existing lines will relieve the overbusy situation of the existing lines and will satisfy the transportation requirement of economic zones and urban areas. To do that can develop the heavy haul goods transportation so to fit the developing transportation needs. In our country, a new large-scale wave has emerged to build high speed railroad as the constructing of the following dedicated-passenger-lines of "Jingjin Area", "Wuguang ", "Hening", "Zhengzhou-Xi'an" and so on in succession. The work needs a great quantity of high tonnage bridge beam erecting facilities. But the traditional ones had already dissatisfied in construction. Therefore the development of high tonnage bridge beam erecting machine should be carried out to satisfy the engineering needs.DF900 guiding beam non-moving lifting bridge erection machine was manufactured for construction of dedicated passenger line specially. Its design absorbed the advantages of the same kind domestic and international facilities, and its significant features were fixed-point holding, simply supported via, lifting system unilayer winded by wire ropes, trans form-span operated easily and so on; the whole machine adoptes PLC to control which possessed the functions of real time display and monitoring, warning; the design of sap pressure was reasonable; two type of operating systems made the construction conveniently.This bridge erection machine was mainly used in the erect project of dedicated passenger line with the operation speed was 200～350km/h and it matched the girder transporter to complete the box beam work.
