Drilling rigs CHZGM URB-4T, Chelyabinsk

Due to the increased torque on the rotator spindle (6000Nm), the URB-4T allows drilling with a large diameter, which increases the reliability of samples.

The pressure at the bottom is 2600kgs, which ensures drilling productivity, and the extraction force is 4600kgs, which allows the URB-4T drilling rig to easily remove the drilling shell from the well. Depending on the diameter, the depth of drilling with sampling can reach 50-60 meters.
