drilling machines in tunnel :

Main feature : the structure is compact, the main body of the machine is short .center of gravity core is low ,easy operation,it is very stable when working. cutting bits of Φ700x550 or Φ750x550 can both be used in the machine,the cutting speed is good when it mines the coal layer which hardness is less than Intermediate Level. The layout of the bits are reasonable,the cutting ability is strong, it has the faction of Internal and external spray, the dustproof effect of is good .

Application scope

It is a kind of cantilever type partly section roadheader, it is used in tunneling of roadway when the roadway section is 8-22 M²coal road or half coal rock . it can also used in railway ,highway, water conservancy for the tunneling.
