A group of more than 80 tons of steel beams, slowly lifted by crane, Xi'an Metro Line viaduct's first start lifting steel beams. The date of completion of two groups four steel erection, weighing a total of 168 tons. Today and tomorrow, the construction workers will be in the frame into 40 cm steel deck pouring concrete, laying the foundation for the future.

"The cross on the Ring of steel concrete composite beam segment, total length of 50 meters, requires the lifting of the steel structure has three sets, six." Xian Guo workers UNRWA Corporation, said yesterday the scene using two 300 ton large car lifting, succeeded two groups 4, total weight 168 tons of steel and accurate installation to a predetermined position.
