Portable Type RCH-3A Underground Core Drilling Rig Exploration Tunnel Mine Drilling Rig
Portable Type RCH-3A Underground Core Drilling Rig Exploration Tunnel Mine Drilling Rig
Product Description
RCH-3A fully hydraulic down-the-hole drilling rig has a split layout, light weight, convenient transportation and flexible operation. It can complete large-diameter cone drilling, large-diameter hard metal drilling, and impact rotary drilling.
The mast of the drilling tower can slide by itself, and the drilling rig can also be retracted, so that the mast of the drilling tower is in close contact with the foundation, which improves the stability of the drilling rig.
