GP72C Underground Hydraulic Drilling Jumbo for Fan Hole Drilling
GP72C middle/long hole production drilling jumbo is specially designed for small cross section tunnel.
It could drill vertical/inclined parallel and fan-shape holes.
High stable double stinger, accurate angel indicator and ergonomics remote control panel,
with high drilling efficiency rock drill, make rock drill more efficient, safe and convenient. Exclusive high stability boom positioning accurate, greatly improved drilling precision, and reduce ore dilution rate.
