PRODUCT FEATURES
1. The Maitong intelligent slot raise boring machine uses mechanical rock breaking, with a roller cone bit for pilot drilling and a cutterhead for reaming in a one-pass raise completion process. It offers advantages such as safety, high efficiency, low cost, and good raise quality.
2. Structural components are made of high-strength steel with a yield strength of 1000 MPa. The machine features a lightweight and compact design and flexible operation.
3. It is tire-mounted for travel, providing high mobility.
4. Its modular design enables rapid disassembly into sections of less than 3 m and quick reassembly, making it easy to transport in a mine cage.
5. All operating actions are driven by dual modes—wireless/wired remote control and manual handle—with free switching and mutual backup, ensuring high reliability.
