Guangxi Longmen Bridge

A "bottleneck" project for Beihai-Qinzhou-Fangchenggang integration

Guangxi's longest planned sea-crossing bridge

Guangxi's first extra-large bridge with a single span exceeding one kilometer

XCMG rotary drilling rigs lend a hand

The Guangxi Longmen Sea-Crossing Bridge is Guangxi's largest sea-crossing bridge and a national key project. It is the "bottleneck" project for the integration of the three important cities of the Beibu Gulf area: Beihai, Qinzhou and Fangchenggang.

The Longmen Bridge has a total length of 7,756 meters. Its main bridge is a single-span double-hinged suspension bridge that crosses the sea in one span, featuring portal-type concrete cable towers 173 meters high. The project is large in scale and subject to many constraints: the terrain is complex and there are numerous underwater reefs in the bridge area; wind resistance requirements are high because the project site has a maritime climate and is prone to typhoons; and the design and construction are difficult, as the suspension bridge structure and the large main span place high demands on construction.

True heroes show their mettle in turbulent seas. Since the bridge's construction began, XCMG rotary drilling rigs, as a pillar of a great nation, have been the main equipment for the bridge pile foundation work.

During construction, XCMG XR600E, XR460E and other rotary drilling rigs each demonstrated their strengths. The XCMG XR600E adopts a box-type slewing platform structure with double large vertical plates, making operation more stable and reliable. Its modular multi-gear power head is designed for soil and rock operations respectively, and the power head's rotation speed can be continuously adjusted in normal mode and rock-entry mode, improving construction efficiency and reducing operator fatigue. The hydraulic main and auxiliary systems use load-sensing control technology for fast response and good controllability. The intelligent thermal control system reduces energy consumption and achieves energy savings.

The XCMG XR460E, as the world's largest back-hoe machine, has become a star product in short supply thanks to hardcore key configurations such as a powerful hydraulic system, a high-torque power head, stepless speed regulation and constant-speed cruise.

XCMG rotary drilling rigs worked together, achieving high pile-forming efficiency and good quality on site, with almost zero failures during construction. The construction contractor and the owner had an excellent experience:

With excellent performance, outstanding quality, remarkable work efficiency and thoughtful after-sales service, XCMG rotary drilling rigs have greatly accelerated the project progress, and we are very worry-free!

We believe that with the help of "XCMG Gold," a new "flying rainbow" will emerge, adding a beautiful scenic line to Guangxi. XCMG rotary drilling rigs are never absent from your every success!
