Trinity "Hercules" shows off muscles! Help Xintang Station of Guangzhou-Shantou Railway Wear "Steel Hat"

The comprehensive transportation hub of Xintang Station is located in Xintang Town, Zengcheng District, Guangzhou，It's Guangzhou-Shenzhen Railway.、Guangshan Railway、The intersection of Guangguan-Shenzhen Intercity Railway and other rail transit lines.。Recently，The south area of the station building needs to install a steel structure grid.。It wasn't that difficult.，ButThere are many difficulties in the actual construction.，The project department was worried for a while.。

Original，The steel structure grid installed this time is different from the usual one.，One is that it is very large.，Length 33.6m、Width 12.75m、High 3.8m，Weight approx. 47 tons，It's like a regular basketball court.。Second, the site is limited.，This top needs to be lifted.“Steel hat”After being hoisted to a height of more than 20 meters,，AgainWalk 40 meters with load to reach the designated position.。

For risk points，The project department has discussed for many times.，But which lifting equipment to use makes them really difficult.。It is necessary to have effective lifting capacity.，And something stable.、Sustained walking ability，At the same time, micro-mobility can not be sloppy.。

Because of the narrow construction environment，The project department initially planned to use Truck_crane/ 'target='_blank' style='color:blue;'>Truck Cranes.，Although the Truck_crane/ 'target='_blank' style='color:blue;'>Truck Crane can meet the lifting requirements,，But travel with load 40mIt's too hard，The efficiency of one lifting and one stopping will be greatly reduced.。At this time, commander Zhang Chao put forward：“Crawler Crane may be used，It has four wheels and one belt.，There is no problem in traveling with load.，And there are many difficulties in hoisting this time.，Track-mounted cranes are safer。”

After much deliberation，The project department adopted Zhang Chao's suggestion.，And choseTrinitySCC4000A-The Crawler Crane undertakes the hoisting task.。At the time of formal operation，SCC4000A-2. Use super-lifting tower working condition（LJDB）42mMain arm+42mJib，Equipped with 100t super-lift counterweight，Super-lift radius: 13m，In-position radius: 40m。

Operator Wang Zihao said：“Lifting and landing this time、Turn around、Walk a long distance、The hole is a test of the equipment.，The most important thing is to walk safely and align the hole.，Stability and stability of SANY Crawler Crane during long distance travel‘Inching’The function is excellent，Millimeter feed，Accurate positioning has been achieved.，The docking of the base is completed at high altitude，The hoisting task was completed safely and smoothly.。”

As the eastern gateway hub of Guangzhou，After the completion of Xintang Station Comprehensive Transportation Hub Project, it will take into account part of the inter-city passenger flow through the high-speed railway and the Pearl River Delta.，Become an inclusive bus、coach、Comprehensive transportation hub for integrated transfer of subway and other means of transportation，It can not only improve the travel environment，Become a new engine to boost the development of Zengcheng，It is also an important part of Guangzhou's construction of an international comprehensive transportation hub.，Accelerating the construction of rail transit in Guangdong-Hong Kong-Macao Greater Bay Area、It is of great significance to promote the opening and prosperity of the Great Bay Area.。
