Underground Tunneling Drilling Rig DF-B1

USE
Electro-hydraulic drilling rig is designed for tunneling up to 40 m2 in size.  A reliable diesel engine Deutz is the drive of the chassis. The drilling rig is equipped with a hydraulic oil station, which operates from the electric motor during drilling and positioning. A sturdy boom with a feeder equipped with a rock drill has an optimum coverage zone and high productivity.
