YSL-180 Reverse Circulation Drilling Rig

Application
YSL-180 reverse circulation drilling rig is mounted on a crawler chassis, driven by full hydraulic system. This drilling equipment is equipped with power head, which is widely used for vertical or inclined drilling.

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-180RC reverse circulation 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 according to different drilling techniques ways. Therefore, it has a very wide range of uses in well drilling.
