The first DF900T guided beam fixed-point bridge erecting machine jointly developed by China Railway Fourth Bureau and Zhengzhou Dafang Large Machinery Equipment Manufacturing Co., Ltd. completed assembly, heavy load test and special equipment on the road of Hehe (Wuhan) Railway on the 20th. After the certification, the first 800-ton double-line full-hole box girder test frame of Hewu Railway was successfully completed.
According to the person in charge of the Hefei Railway Bridge and Bridge Team of the China Railway Fourth Bureau, the DF900T guide beam fixed-point bridge erecting machine has independent intellectual property rights, with a maximum span of 32 meters and a rated lifting capacity of 900 tons. It combines the advantages of other guide beam bridge erecting machines. It has infrared positioning and electronic monitoring functions. It adopts the high position of the guide beam, which can easily solve the problem of the first and last cross-beams. The through-frame beam is all supported by simple support. The beam machine can be used as the load-bearing device of the box girder or as the support for the via hole of the bridge machine. The two functions are organically combined perfectly to ensure the structure of the whole machine is light and convenient. The whole machine adopts frequency conversion speed regulation, which can reduce the running impact, ensure the safe and stable process of the frame beam, and use the advanced sensor image capturing system to keep the beam beam process in the monitoring state.
In addition, the supporting equipment of the DF900T guide beam fixed-point bridge erecting machine is a tire-type hydraulic automatic lifting flat transport vehicle, which is listed as the national 863 plan project. It is the first large-tonnage railway box girder transportation equipment successfully developed and manufactured in China. .
