On April 26th, at the construction site of the Meilong Extra Large Bridge of the Shenshan West Expressway renovation and expansion project, an intelligent bridge erecting machine was lifting and operating, and the bright red color was exceptionally eye-catching under the sunshine. This is the world's first pile beam integrated bridge building machine; Gonggong ID” Developed by China Railway Science and Technology Group and manufactured by Jiangsu PG Slot Crane Machinery Co., Ltd., it has been successfully put into use and completed 10 span operations. This device realizes a new bridge construction mode of factory prefabrication, lean management, modular assembly, and intelligent installation, leading bridge construction technology into the 3.0 era.

It is reported that; Gonggong ID” The bridge has a length of 92 meters, a width of 13 meters, a self weight of 575 tons, and an effective span of 48 meters. It is an intelligent equipment tailored for the special working conditions of the project site with dense riverbanks, lakes, and swamps, and is close to the Guangdong Haifeng Bird Provincial Nature Reserve. It has the characteristics of continuous operation, accurate positioning, high efficiency, and environmental protection, and has applied for several national invention patents. The bridge erecting machine adopts the Beidou positioning system for pile driving, achieving a complete set of drilling, pile driving, beam erection, and bridge pier assembly; Air” Homework, without the need for other equipment to assist in construction, is suitable for areas such as shallow lakes, swamps and wetlands, environmental protection zones, and bustling urban areas, reducing damage to the ecological environment. In addition, the device can increase efficiency by more than three times and reduce construction costs such as installation and demolition.  

Project leader Shi Bing introduced that a total of 3 units of this type of intelligent equipment were built in the same batch. Currently, the first unit has been successfully put into production, the second unit is in the on-site installation stage, and the third unit is also being shipped one after another. Affected by the COVID-19, the road transportation in some risk areas was interrupted. The company timely maintained communication and cooperation with the freight transport unit and the epidemic prevention department in the passing areas, and delivered the products to the site as soon as possible under the premise of the policy; At the same time, the project department has arranged a dedicated person on site to be responsible for receiving and coordinating after-sales service work.
