Product Description

180T road bridge launcher equipment is a professional design for U type bridge machine required for erection of city rail transit construction beam. As a kind of structure section, the U beam has good noise reduction effect, low construction height, high utilization ratio of cross section space. Because of U type beam for thin-walled opening structure, the traditional bridge rack beam cannot be applied directly. Unable to realize the traditional function of carrying beam traversing, beam body installation can only be achieved by traversing the crane. Therefore Huada Heavy Industry U type bridge erecting machine with "front overhead crane beam, acquired vehicle girder, two cranes synchronous walking, then synchronized fall beam" of the process, simple operation, safe and stable.

 
U model bridge girder beam launcher crane is mainly used in the Inter-city railway building projects, such as metro way, light rail transit, etc. As economy and public transportation develop, inter-city railway is vigorously building in developing countries, such as China, Indonesia, Philippine, Vietnam, Myanmar, Russia, Kazakhstan, etc.

As the great project of “One Road One Belt” implement deeply, this “U” girder beam launcher cranes are of great potential market in the world.

“U” bridge girder is just like a tunnel without cover; which not just largely reduces the overall height of the viaduct bridge structure, but also largely shield the train noise.
