Reverse Circulation Drilling Rig
Request a Quote
Reverse circulation drilling rig is a hydraulic crawler type drill rig which is new model, high efficiency, environmentally friendly and has multi-functions. It uses gas lift reverse circulation drilling technology and the resulting dust from the drilling can be collected effectively via dust collector to avoid pollution to the environment. Slag can be collected using cyclone separator, which can be used for sampling and analysis work in geological exploration department. It is a preferred drilling device for geological exploration, water well, monitoring well, geothermal pump air conditioning hole and others deep hole drilling.

- Fast drilling — 20m – 40m drilling per hour
- Large torque — meet the requirements of air drilling, convenient for high and low speed adjustment
- Long stroke — meet the feeding requirements of the forward and reverse circulation 3m drilling pipe
- Wide angle — meet the construction requirements of vertical and inclined holes
- Good stability - mast sliding with outriggers to improve the stability of drilling
