At 4 am on May 14th, the middle arch section of the main arch of Liuzhou Guantang Bridge was hoisted into place. This hoisting has respectively created three “world first” records in overall lifting height, overall lifting weight and the lifting span of arch rib.

From the project department of Guantang Bridge, the reporter learned that all the floating cranes used in the domestic inland river could not satisfy the hoisting height and weight of the middle arch section of Guantang Bridge. Therefore, the technical team decided to adopt the construction method of "low level assembly and integral lifting", which is firstly invented in China, and specially designed a special construction plan of up to 300 pages for this purpose.

When the process was used for construction, the middle arch section was assembled at a low level near the river. For the convenience of assembly, the project department itself has designed a "bauhinia type" water support. For the overall lifting height of 67.27 meters, the arch rib span of 262 meters and the overall weight of 5885 tons, only in the link of the overall lifting of the middle arch section, the project department has created three "world first" records.
