• Applications The YSL-220RC reverse circulation drilling rig is a tracked chassis loading, fully hydraulic driven, and power head drilling rig. It is a drilling equipment suitable for vertical or inclined drilling, and is suitable for the following process methods:
  Non circulating liquid spiral drilling (dry drilling)
  Air Downhole Hammer (Pneumatic Impactor) Drilling
  Mud positive circulation drilling
  Air Downhole Hammer and Pipe Drilling
  Multi medium reverse circulation drilling
  The drilling rig is suitable for different drilling techniques, so it has great adaptability to various formations and complex working conditions. It can effectively solve the problem of difficult drilling in loose cover formations, gravel layers, and fractured bedrock formations, and has a wide range of applications.
  The drilling rig is mainly suitable for the construction of RC reverse circulation/water well drilling, as well as the survey and construction of ground source heat pump holes and small foundation pile holes.
