Xr220a rotary drilling machine drilling 2 meters hole can reach 80 meters, its maximum drilling depth is 80 meters, the maximum aperture is 2 meters.
You can see the instructions for the use of the machine, especially the geological conditions If the geological conditions are special, even if they can hit, the damage to the machine is also greater!
Attention is conditional, and there is the maximum drilling depth is 79 meters, there are 1 meters gap, if you count the drill bucket distance, barely enough.
According to the technical parameters of XCMG XR220A, if the friction resistance type 6 section drill rod can drill 79 meters at maximum, the maximum aperture is 2 meters without bushing.
