HF260RC Reverse Circulation Core Drilling Rig

overview

HF200RC series reverse circulation 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.

►Features
1. All parts of he 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. 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
6. 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.
