Specifications

the reverse circulation drilling machine can drill max1.5m diameter,80m Depth for special stratum with high drilling efficiency

 

      CJF-15Percussion Reverse Circulation drilling machine mainly used for the construction of deep
foundation large bored piles(hight-rise buildings,bridges,irrigation works,etc.) and the
work of large diameter bored piles and underground continuous wall.It can be suitable
to more complex stratum,and with great efficiency especially in the terrain containing
pebbles and rocks.It adopts reverse circulation technique with much more higher
efficiency than percussion drillers of type CZ,and reduces the abrasion of aiguilles.

Characteristics

1 Mechanical transmission with excellent stabilization and trustiness
2 Hydraulic raising and lowering mast with few quiver and fine security
3 Can be removed by hydraulic track easily
4 Landscape orientation remotion can be achieved with exchengeable hydraulic underprop
