Keywords:Girder erection, Process shortening, Just above the railway business line

Although the plan was to build a free-pass girder directly above the business line using a 550-t suspended all-terrain crane, the work was to be performed at the top of the track during nighttime power outage work.Therefore, there was a risk of process delays and occupational accidents. it was high. For this reason, in this work, the free passage girder was erected together with a 600-ton crawler crane and buggy weight, thereby significantly reducing nighttime power outage work, shortening the process and preventing work accidents.
