Product description

1.Brief introduction of CJD-300 crawler pneumatic water well drilling rig

CJD-300 crawler pneumatic water well drilling rig is a pneumatic water well drilling rig jointly developed by Shandong Machinery Group and Jining Master Machinery Research Institute. It is mainly used for drilling operations in hilly, mountainous and other rocky areas. The advantages of hole depth, fast footage, flexible movement, and high efficiency have been widely used in industrial and civilian drilling, ground temperature drilling, environmental monitoring drilling and other occasions.

2.Features of CJD-300 crawler pneumatic water well drilling rig

  • Using the principle of pneumatic impact, the drilling footage is fast and efficient.
  • Equipped with steel crawler chassis, it has strong cross-country performance and can easily cope with various complex work sites.
  • It is equipped with hydraulic high outriggers, which is convenient for loading and unloading trucks, saving lifting costs, and can be used for drilling rig leveling to maintain the stability of the fuselage.
  • Equipped with high-power diesel engine with strong power, which can effectively meet work needs.
  • Equipped with hydraulic lifting and lowering composite drill boom, which saves space and provides powerful lifting force for deep hole operations.
  • The drilling rig is equipped with a hydraulic feed system, dual hydraulic motor power heads, chain transmission and hydraulic cylinder propulsion, with large torque and high drilling efficiency.
  • Equipped with quick rod unloading device, which can quickly disassemble the drill rod, saving time and effort.
  • Centralized operating handles, reasonable layout, safe and feasible.
  • Excellent workmanship, durable, and low maintenance costs.
