Dunrui Holdings has made a total investment of 300 million yuan, and the second - phase project of TBM cutter tools and TBM hydraulic rock bolt drilling rig systems has been launched in Liaocheng!

Dunrui Holdings has invested in setting up a production line in Liaocheng, capable of manufacturing 50,000 sets of TBM cutting tools and 2,000 sets of TBM hydraulic anchor drill systems annually.

Our company's high-end equipment manufacturing base currently under investment and construction in Liaocheng focuses on the research and development and production of key equipment in the fields of tunnel engineering and mining. The project is planned to have a total investment of 300 million yuan, with a designed annual production capacity of 50,000 sets of TBM (Full - face Tunnel Boring Machine) cutters and 2,000 sets of TBM hydraulic rock bolt drilling rig systems. As the "teeth" of the tunnel boring machine, the performance of TBM cutters is directly related to project efficiency and cost. This project will strive to break the foreign technological monopoly and achieve the localization and intelligent upgrading of key components. The hydraulic rock bolt drilling rig system is the core equipment for TBM support, which is of great significance for enhancing the safety and automation level of tunnel and mining operations.
