CJD Series Crawler Pneumatic Water Well Drilling Rig
1 Introduction of CJD Series Crawler Pneumatic Water Well Drilling Rig
CJD series crawler pneumatic water well drilling rig is a kind of pneumatic water well drill jointly developed by HUAXIAMASTER GROUP and Jining Master Research Institute. It is mainly used for drilling operations in hilly and mountainous areas where there are many rocks. It has the advantages of large drilling diameter, deep drilling, fast penetration, flexible movement and high efficiency. It has been widely used in industrial drilling, geothermal drilling, environmental monitoring drilling and other occasions.â??
2 Features of CJD Series Crawler Pneumatic Water Well Drilling Rig
2.1 Using the principle of pneumatic impact, the drilling footage is fast and the drilling efficiency is high.
2.2 Equipped with steel crawler chassis, strong cross-country performance, easy to deal with a variety of complex working sites
2.3 Equipped with hydraulic high outrigger, it is easy to load and unload the truck, save the hoisting cost, and can be used for leveling the drilling rig to maintain the stability of the fuselage
2.4 Equipped with high-power diesel engine, strong power, to meet the needs of work.
2.5 Equipped with hydraulic take-off and landing composite boom to save space and provide strong lifting force for deep hole operation.
