Reverse Circulation Drill Rig For Soil Survey

ZJRC-300 type reverse circulation drill rig for soil survey is a new multi-functional, high-efficiency, environmental-friendly, and multi-crawler mounted drilling rig machine. It adopts the latest foreign gas-lift reverse circulation drilling technology, which can effectively collect rock dust and avoid environmental pollution through dust collectors. It can also collect the slagging of the cyclone separator, which can be used for sampling analysis in the geological exploration department. It is a geological exploration drilling, drilling wells, monitoring wells, ground source heat pump air-conditioning, and other deep holes of choice for equipment.

ZHONGJIN full hydraulic crawler RC 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, outriggers, hoisting, walking, and other systems all implement hydraulic systems, which greatly reduces labor intensity and improves construction efficiency and quality.

ZHONGJIN® RC Drill Rig Features   * Compact Dimensions * Extending Undercarriage * Stronger Frame * Simple Control * Easy Maintenance * Multi-functional * High-efficiency and environmental-friendly
