Air Reverse Circulation RC Drilling Rig for DTH Mning Drilling in
Depth 150m
Product Description
The RCJ150RC drilling rig is a fully hydraulic crawler drilling rig
that is good at drilling vertical or inclined holes and supports a
variety of drilling technologies, such as auger drilling and down -
the - hole hammer drilling. It is suitable for processing complex
geology, such as soft layers and broken layers, so it is suitable
for a variety of drilling projects, including RC drilling, water
wells, geothermal holes and small foundation pile holes.
The drilling rig can be used in a variety of compressed air on the
ground hole reverse circulation drilling. The lifting system,guide
compensation, drill pipe loading and unloading, rotation and feed,
legs, winch, walking and other system to achieve all of the
hydraulic system to significantly reduce the labor intensity and
improve the efficiency and quality of construction .
