Drilling Rig ZBO U15A

ZBO U15 drilling rig designed for technological underground drilling down, up and under any angle fully replaces import analogs and compared to them has the following advantages:

  • modular explosion proof design for use in aggressive environments;
  • complex supply with a set of drilling tools;
  • service;
  • ZBO U15 price is lower than of similar imported models.

Due to compact size and power drilling rig can be used in limited space conditions. Modular design and several equipment options allow to use ZBO U15 also for exploration drilling.
