DL3-b Underground Production Drilling Rig for Mine and Tunnel:

DL3-b hydraulic mining drilling rig is a cantilever type deep hole mining production drilling rig, which is specially designed for long-hole drilling in underground mines or tunnels. It is often used for doing parallel and fan-shaped holes in underground non-coal mine mining, and it can also do anchor holes. It adopted full hydraulic rock drilling. It can drill a hole of 20 meters depth once a time, and the hole diameters of 64/76/89mm can be chosen. All diesel power for walking, Articulated chassis, four-wheel drive, climbing up to 14° slope, to meet with the flexible transition between roadways.
