GY150A Core Drilling Rig is a multi-purpose engineering drilling rig suitable for high-speed drilling engineering in complex rock formation. CHANGTAN serial drilling rigs covers all the main foundation and drilling technologies with a range of models whose characteristics, capability and performance find application in every operating condition.
Applications:
1. Drilling construction for high-rise building, highway, railway, bridge, port, harbor work, dam and tunnel.
2. Small-diameter hole foundation piling drilling.
3. Solid mineral exploration.
4. Anchoring engineering for battered slope.
5. Geothermal pipe-installing for heat pump.
Features:
1. Function of rotary percussive drilling.
2. Wide range for the great angled drill holes from surface and angles in underground drill holes.
3. Easy disassembling for transportation to most inaccessible areas.
4. Good stability and high reliability.
