Key Operational Benefits

300m deep drilling, fits all kinds of strata
Equipped with original 85KW Yuchai diesel engine, it delivers stable power continuously under harsh field conditions including high temperature, drought and high altitude, featuring low failure rate to avoid frequent maintenance downtime during long-site construction.
Dual drilling modes, DTH air & mud drilling available
4T axial pressure matched with 24T main winch lifting force prevents slipping when drilling loose gravel and hard granite, saving labor and time on pulling deep drill pipes and casings to cut on-site labor costs greatly.
30° climbing crawler, flexible movement on mountains & orchards
The whole machine measures 4.8×1.9×2.35m with total weight of 8 tons, fully loadable into standard 20GP container without disassembly, reducing shipping & assembly labor cost for export sea transport.
