China Railway No.4 Engineering Group Co., Ltd (CREC4) completed assembling the first beam hoist machine on July 8 for the No 3 Bid of Chaohu-Ma’anshan Intercity Railway, a 76-kilometer high-speed railway linking Anhui’s provincial capital of Hefei with Ma’anshan city.
The beam lifter, as the the largest tonnage beam lifting machine in China for high-speed rails that can hoist a maximum of 1,100 tons of beams, lifted a main beam for the construction site on July 8. It also showcased the first completion of beam lifter assemble in the whole railway line, providing a strong guarantee for the subsequent assembly of rack transport equipment and the erection of the first box girder.
The intercity railway, which starts at Chaohu East Station at Hefei’s Chaohu city and ends at Ma’anshan South Station after traversing the Yangtze River, is also a major part in the Hefei-Shanghai section of Shanghai-Wuhan-Chengdu Transport Corridor in the nation’s “eight vertical and eight horizontal” HSR network. With a designed speed of 350 kilometers per hour for the trains, the line will help bolster the integrated development of the Yangtze River Delta and is conducive to the development of the Yangtze River Economic Belt.
Paying high attention to the the assembly of the 1,100T beam lifter, the project department held several seminars on discussing the assembly work and designed scientific and safe plan for this large equipment. The participants also attended special training, witnessing detailed arrangement on the inspection and acceptance of large cranes, the qualification of special operators, hoisting operation process, division of responsibilities of on-site operators and safety precautions. All these helped to ensure the smooth assembly of the beam lifter.
The mains tasks for the No 3 Bid include the erection of 567 box girders and a track laying for 145.8 kilometers, with all the beam erection job done prior to November 2023.
