Introduction of cantilever type tunneling machine

The cantilever tunneling machine is mainly used for rapid tunneling of coal roadway, semi-coal roadway, soft rock roadway and tunnel with a hardness of less than f7.5.The stretch design of cutting section is adopted.The hydraulic system adopts constant power, pressure cutting and load sensitive control.All key components are of well-known brands.It can realize continuous cutting, loading and transportation.

24 m2 positioning cutter cut surface, cutting hardness acuities were 75 mpa, longitudinal slope + 16 °.

Main characteristics of cantilever type tunneling machine

1. The cutting section is retractable with a telescopic travel of 550mm.

2. With internal and external spray and external spray front, reasonably design the nozzle position and enhance the external spray effect.

3. Large inclination Angle at the bottom of the spade plate, large ground gap of the whole machine and strong climbing ability.

4. The flat structure of the intermediate transport plane is smooth to connect with the blade, high and smooth to transport.

5. The key parts adopt well-known imported brands, and the components have good universality.

6. The hydraulic system adopts constant power, pressure cutting and load sensitive control.

7. The electrical system adopts the new comprehensive protection and modular design, which has the dynamic display function of liquid crystal Chinese characters.

8. Low center of gravity and good machine stability.
