TR series cantilever type tunneling machine is a new form of tunneling machine developed to meet the needs of tunnels of various sections. This series of tunneling machine has strong rock-breaking capability, high construction efficiency and wide cutting range, and comprises targeted professional models for water conservancy and subway tunnels with small and medium-sized sections as well as highway and railroad tunnels with larger sections, which can meet the construction requirements of tunnels. The tunneling machine has strong geological adaptability and can be stably operated for construction in tunnels with rock hardness within 120MPa: With stable cutting performance and wear-resistant cutting head, it can excavate semi-circular, oval, rectangular, horseshoe-shaped and other special-shaped sections and sections with abrupt changes. The tunneling machine adopts hydraulic and electric components of internationally well-known brands to ensure the operation and control reliability of machine, and is equipped with spray system and fan for dust removal to provide a low-dust environment for construction workers. The complete machine has high configuration, good stability, high automation, safety and reliability. 

Advantages: 

1. It adopts new cutting mechanism, conical pedestal cutting head and double helical arrangement of cutting teeth. 

2. The surface of loading system is made of high-strength wear-resistant steel plates, with good wear resistance and strong discharge capability. 

3. The complete machine has a spray system and onboard dust removal device to reduce dust pollution. 

4. It can be remotely controlled to effectively protect operators and equipment. 

5. The air cooling technology with good cooling effect is adopted to ensure that the main unit operates normally without external water supply. 

6. Components of internationally well-known brands are adopted, and a cable reeling system is fitted for the convenience of laying, reeling and unreeling cables to save manual effort. 

7. The hydraulic system adopts constant power, pressure shut-off and load-sensitive control technologies.
