Tunnel

We have Roadheader, Underground scaling breaker and Excavator for Tunnel.

1.Roadheader

Equipped with a milling head, this machine can work during coal or semi - coal tunnel boring with a hardness of 4F without the need for gunning. This machine is equipped with quick coupler, and the bucket and milling head are interchangeable during rock tunneling. After blasting, the digging bucket is used to load the slag, realized the purpose of one machine for dual use. The main hydraulic parts adopt a spur gear gearbox imported from Germany, which is driven by a high - torque hydraulic motor to ensure that the milling head can cope with more severe high - load working conditions. This machine is equipped with internal spray and high - pressure external spray device, which has good dust extinguishing effect. Due to the large weight of the milling head, the whole machine adopts the design concept of super structural parts to ensure that the whole machine has sufficient weight, and the body is stable when cutting rocks, improving efficiency. It adopts the rotary table structure of the TBM, the quality is stable and reliable.

2.Underground Scaling Breaker

The machine is suitable for rock loading, bottom cleaning and excavation of frozen soil in coal mines, metal mines, non-metallic mines, shafts, inclined shafts and flat tunnels. Compared with the traditional manual bottom cleaning, the use of the machine greatly saves labor costs while improving the operation efficiency and improving the working environment. The operator works under the protection of the cab, which is conducive to safe production. Compared with the traditional diesel-powered mini excavator, due to the use of electro-hydraulic system, this machine has the characteristics of energy saving, low noise, no exhaust gas pollution and high efficiency, and is more suitable for underground use. The machine has compact structure, small size and small sub-assembly parts, which is convenient for vertical use. This machine adopts the minimum swing structure, and its tail will not exceed the width of the car when the body is rotated, so it is more suitable for the narrow space underground.

3.Digging Transporting Breaker All in One Machine

This machine uses crawler to travel, with large driving force, wide pick-up range, can be full - section rock loading, no dead corner, no manual assistance to clean the working surface, and can quickly complete the work of risk removal and ditching.
This machine adopts imported hydraulic pilot control lever system, which is light control, strong control ratio and high reliability.
The power of this machine can be equipped with diesel and electric integration, and a variety of supporting accessories can be selected.

4.Excavator

The machine is suitable for rock loading, bottom cleaning and excavation of frozen soil in coal mines, metal mines, non - metallic mines, shafts, inclined shafts and flat tunnels. Compared with the traditional manual bottom cleaning, the use of the machine greatly saves labor costs while improving the operation efficiency and improving the working environment. The operator works under the protection of the cab, which is conducive to safe production. Compared with the traditional diesel - powered mini excavator, due to the use of electro - hydraulic system, this machine has the characteristics of energy saving, low noise, no exhaust gas pollution and high efficiency, and is more suitable for underground use.
