Recently，Bid 4 of Gannan Avenue Elevated Expressway Project（Nankang section），As one girder after another rises.，The main structure is gradually emerging.，It marks another step towards the formal completion of the project.。

A single girder weighing more than 100 tons，By TrinitySAC4000C8 All terrain crane、SCC1350A-6 Crawler crane joint lifting。SAC4000C8 Use arm length 21.1m working condition，Working span 5 m，Torque% 53%，SCC1350A-6 then span 9.13 meters，Percent of moment 72%。

Construction site，The workers on the ground assisted two cranes to lift the two ends of the girder respectively.，And thenSCC1350A-6 Move the position slowly when traveling with load，SAC4000C8 is based onSCC1350A-6 Slowly lift the upper arm in the walking position.，At the same time, constantly adjust the angle.。After the girder reaches the designated position，Then hook slowly according to the instructions of the workers.。

Fang yuan, a service engineer stationed at the scene, said.：“The weight of the girder lifted this time is heavy.，Large volume，However, the requirement for accuracy is very high.。At the same time，Affected by cross operation，The construction site is very limited，It tests the micro-mobility of the equipment and the strength of the operator.。The two lifting equipment are working steadily.，It took less than five hours.，Put all six girders in place.。”

In order to do a good job of beam erection，The Project Department shall combine with the actual situation，On the basis of doing a lot of analysis work.，Organize the participating units to compile a rigorous special construction plan，Scientific organization of construction，Ensure the safety and reliability of project quality，Reasonable and orderly construction process。

Fang yuan said：“Last year, due to the continuous epidemic,，The progress of the project is seriously lagging behind，It's time to catch up with the schedule.，The construction party has very high requirements for equipment.。This time, more than 20 Sany cranes participated in the construction of Gannan Avenue Elevated Expressway Project.，Among them, large-tonnage equipment accounts for about 30%。I'm stationed here.，It is to ensure that the equipment can be constructed in the best working condition.。”

It is understood that，Bid 4 of Gannan Avenue Elevated Expressway Project（Nankang section），Yes“Four horizontal, six vertical and one ring”An important part of the expressway network。The total length of this section is about 10.1km，Two laying forms of overhead and ground are adopted。The total project duration is 30 months.，The total investment is about 2 billion yuan.。

After the completion of the expressway,，It will expand the attraction of urban radiation.，Enhance the advantages of urban location，Further improve Ganzhou's urban transportation facilities，Improve the urban living environment and ecological environment，To improve the quality of urban functions、It is of great significance to enhance the radiation-driven capacity of central urban areas.。
