With the acceleration of urban subway construction pace, adhering to create value for customers, Tysim has upgraded the design of KM220 telescopic arm recently. The upgraded KM220 was successfully completed at the Nanchang test base in Jiangxi Province.Under the leadership of Mr Xiang, the Director of R&D department, the bucket capacity is upgraded from 0.6 cubic meters to 1.5 cubic meters. The speed of ascent and descent has also been improved. The upgraded KM220 will save time for Nanchang subway construction to begin at the end of August.

This upgrading work has involved more than half of the entire R&D team due to the time constraint.  It is worth mentioning that master Sun，the state qualified Rock and soilcraftsman cum model worker from JiangXi ZhongHeng and the staff of his studio have performed an innovative construction method with the upgraded KM220. The application of this construction method has greatly improved the construction efficiency, an icing on the cake for this product upgrade.
