Dalian Heavy Industry·Zhangzhong Group has recently successfully developed 9 series of tools for shield machines, and its full-section shear strength test parameters have reached the performance indicators of world-class tools.
For a long time, due to the special material of the shield machine and the complicated manufacturing process, only a few well-known enterprises in the world can manufacture it.
In addition, the shield machine tool used for cutting and excavating the soil layer of the excavation is a consumable part and needs to be replaced frequently. The tool imported from abroad is expensive and has a long delivery period. In order to break through this key issue, Dalian Heavy Industry·Hangzhou Group has set up a project team for the development of shield cutters. After five months of hard work, it has independently developed and developed its own knowledge. The nine kinds of shield machine tools of property rights can be used for mud water shield machine, earth pressure balance shield machine and composite shield machine.
