Bridge erecting machine is the core lifting equipment in bridge construction, which can move on bridge piers or already erected beam sections, and complete the installation and assembly of prefabricated box girders span by span. The world's first thousand ton new energy bridge building machine, "Yinglong", is a device independently developed by China Railway Science and Technology Group Corporation and awarded the title of "Top Ten Key Equipment of Central Enterprises". With characteristics such as "deformation ability", "mechanical intelligence brain" and "green heart", it solves the extremely complex bridge building problem with green intelligence.

Transfiguration Skill

The "Yinglong" adopts a new scheme of double span erection, which is a modular derivative design based on the traditional single main beam bridge crane. It can freely disassemble and reassemble the support leg structure, and flexibly switch construction modes. It can install single track box girders weighing over 460 tons under extreme conditions, as well as double track box girders weighing thousands of tons under conventional conditions after rapid conversion.

Mechanical intelligence brain

It is equipped with a self-developed intelligent safety management system, which integrates six key systems including environmental perception, posture detection, pressure sensing, intelligent anti overturning, image recognition, and automatic alarm. It supports "one click hole passing" and "one click beam lifting" operations, with positioning accuracy reaching millimeter level. At the same time, it can monitor and collect safety data of key processes in real time, and judge the safety status on its own.

Green Heart

The Yinglong has successfully applied new energy technology to bridge building machines for the first time globally, equipped with a power source system of "range extender+power battery", which not only ensures continuous operation but also achieves fuel consumption savings of over 40%.
