TRD-280 Top-drive Rotary‑Percussive Water‑Air Dual‑Use Drill Rig
- Water-air dual-use drilling
- 9800 N·m power head torque
- Rubber crawler with 4 legs
- 450m mud, 280m DTH depth
TRD-280 Top-drive Rotary‑Percussive
Water‑Air Dual‑Use Drill Rig
Mechanical top‑drive · mud & DTH · for loose soil & bedrock (F6‑20)
⚡ TRD-280 integrates mud rotary and DTH air hammer drilling in one mechanical top‑drive system. It overcomes the difficulty of air DTH in loose overburden and low efficiency of mud drilling in hard rock, gravel and boulders. Ideal for water well drilling, geotechnical investigation and core extraction with high efficiency.
