Working with Second-hand rotary drilling rig equipment in rock demands precision. Here’s how to improve boring speed and durability using SANY used rotary drilling rig and XCMG used rotary drilling rig setups.
1. SANY SR360 + Tri-cone Bit + Auger Cleaner
This SANY used rotary drilling rig thrives in fractured granite and hard shale. The tri-cone bit increases penetration, while the auger cleaner avoids clog buildup.
2. XCMG XR280D + Pilot Barrel + Torque Guide
Effective in dry and abrasive zones, this XCMG used rotary drilling rig keeps vertical bore integrity even under vibration stress.
3. SANY SR235 + Conical Tooth Bucket + Low-Vibration Mode
This Reconditioned rotary drilling rig setup is a cost-effective option for deep boreholes. Its variable-speed torque avoids tool failure.
Helpful Hints:
- Pre-inspect bits before each shift
- Adjust rotational speeds based on feedback
- Use casing in deep fractured rock zones
