ZQJ-300 / 6 frame column pneumatic drill 
 Pneumatic drill rig frame column pillar drill stand 
 ZQJ-300 / 6 air frame is driving head pillar drill rig, the main use of efficient spiral drill and carbide drill bit for rotary drilling. Widely used in coal seam exploration of water, water, gas and other exploration drilling construction schedule. Host has a positive and reverse function easily in and out of hole drilling; giving into the use of independent motors, to enter force, the failure rate at the end. By controlling the volume, easily adjust the feed rate; console and the host separation, remote operation control drilling construction; unique dual silencer structure, the noise to a minimum, improve your work environment; host, support, Plug and play console, handling convenience.
