ZQJC series pneumatic column-mounted drilling rigs can be widely used in water exploration, drainage, gas detection, drainage and other drilling constructions. This series of drilling rigs use compressed air as a power source, which is safe to use and has no hidden sparks. The whole machine adopts modular design and is divided into three parts: main machine, guide rail and column. It is convenient and quick to install and transport, simple to operate, and convenient to maintain. It is especially suitable for high gas mines and industrial and mining applications with frequent drilling displacements.

·The power output is stable and strong, the drilling speed is fast, and the construction efficiency is high

·The self-contained water supply mechanism adopts a unique packing type seal, which replaces the ordinary seal ring type seal, which increases durability by more than 10 times

·The guide rail is widened by 40% to improve the stability of the drilling rig during construction

·The rack is enlarged to minimize the possibility of tooth breakage and damage.

·Maintenance-free single hydraulic support, stable and reliable,

·to prevent the phenomenon of no rise or fall caused by liquid leakage

The pillar adopts an extra-long stroke of 600mm, and the inner pillar opens and lowers independently, which is convenient for drilling and accurate positioning
