Cooperated with the world leading bridge crane manufacturer, the cutting-edge technology connect with the unique fabricating factory, the overall designing technology has reached leading level within both home and abroad. Along with reasonable and optimized design of bridge crane structure, maximum meet the needs in strength, stiffness and stability. To fully satisfying different customer requirements, our company takes full advantages of combining crane design with site condition, such as fabricate course, testing, transportation, installation and maintenance, possibly make every step easy and individual. In particularly, with computer optimization design box beam, low dead weight effectively reduces the cost in which workshop built with steel structure.
