YSL-220 Reverse Circulation Drilling Rig

  •  YSL-220 Reverse Circulation Drilling Rig
  •  YSL-220 Reverse Circulation Drilling Rig

The YSL-220 RC drilling rig is mainly applied to RC drill/water well and observation well, geothermal hole, small buildings foundation piles.

Drilling techniques way of the following:

  • Dry drilling
  • Down-the-Hole hammer drilling
  • Direct circulation- Mud Rotary
  • DTH hammer drilling with casing
  • Multi-medium reverse circulation composite drilling

YSL-220 reverse circulation (RC) drilling rig is suitable for different drilling ways, so it is highly adaptable to all types of strata and complex working conditions. The versatile RC drilling rig is able to resolve the difficulty of boring in the stratums such as soft and loose cover ground condition, the cobble layer and also the bedrock fracture zone.
