Hydraulic CBM Drilling Rig

The Hydraulic CBM Drilling Rig is designed for coal bed gas drilling, water well drilling, mine rescue drilling, shallow petroleum/natural gas drilling and mineral investigation etc.
· Truck chassis mounted for easy transport and less working intensity.
· The whole rig is driven by hydraulic and equipped with kinds of safety guards on controls of pulling force, feed force, and output torque and drill head feed locking, etc.
· Due to design of two gear shift on drill head, difference torque and rotation speed can be realized and meet requirements of different hole size and drilling technique, max. Torque 27,500 Nm for big hole size drilling and max. Rotation speed 300 rpm for coring drilling.
· Drill head can be set to 80° angle and main spindle floats 102 mm, both for easy rod handling and less working intensity.
