RC Drilling Rigs General Introduction
Reverse Circulation (RC) drilling rig is a type of drilling equipment commonly used in mineral exploration and resource evaluation. It operates by using compressed air to drive a dual-walled drill string, which pumps the drilling cuttings and rock samples up through the center of the drill rods to the surface. The RC drilling method is popular due to its ability to quickly and accurately collect large quantities of high-quality samples in challenging geological conditions, such as hard rock or areas with limited access.
SC-150RC SC-200RC SC-300RC RC drilling rig is full hydraulic top drive type crawler drilling rig which is independently developed by us, it can be used for mining investigation, geological investigation, borehole for water well and observation well, borehole drilling for GSHP system and so on.
Crawler Multifunctional Hydraulic RC Drilling Rig Features:
1. all parts of the drilling rig are installed together on the turning platform with crawler chassis, it moves convenient and has good maneuverability.
2. rig with power head has long feed stroke so that it can shorten the time of installing or unloading drill rods and improve the drilling efficiency.
3. rig with full hydraulic transmission and control operates easily and flexibly. it can show smooth operation and reliable work.
4. rig with dual -channel power head has strong torque as well as pulling force, it has strong ability to deal with accidents.
5. patent design of telescoping system in output shaft will effectively protect drill tools.
6. machine installed a hydraulic clamping & breakout system in order to automatic wrench the drill pipe and tools, both assistant time and lobar intensity are reduced during the drill work.
7. drill head with dual motor drive has a variable speed and wide speed range, it is suitable for the application of pneumatic DTH hammer drilling and alloy drilling.
