KD – 150 Tunnel Drilling Rig
KD-150 Boring Rig is a type of machine with hydraulic feeding for tunnel boring, applicable to the exploration of metal mine, nonmetallic mine and coal mine, and the hole drillings for grout, drainage and observation in the corridor at hydropower station. Features:
-
With hydraulic automatic feeding device, elevated drilling efficiency, reduced labor strength
-
Small volume, lightweight.
-
Using double pillar support, compact structure and small operation area occupancy
-
The boring machine and pump are driven separately, convenient for the arrangement at work site.
-
Lightweight, high detachability, easy transportation and installation.
