Bryant AF20RW tunnel dug milling machine milling head Boring head

Milling digging machine, it is mounted on a hydraulic excavator and other equipment to work as a milling machine is digging equipment. In the low hardness of rock wind rock, tuff maximum reach 25 ~ 40m3 / h (with the density of the rock fragmentation varies), can also be Milling dig unreinforced or a small amount of reinforced concrete, the use of equipment in 300 tons of milling digging machine digging machine, milling can be easily dug with less than 30mm diameter reinforced concrete. Precise control of construction: cost arising from the trim structure can quickly and accurately outline in tunnel excavation, not only make the construction units can solve the headache problem of under-excavation, thereby reducing construction unit also "rather super do not owe" Raise the issue . Safety, the use of milling digging machines replace the manual soft rock or broken rock tunnel boring, eliminate the risk of the excavation working face in front of the workers, thus greatly improving the safety of tunnel construction.
