It is after years of market investigation and research! Its perfect shape, reasonable structure, simple and wide adaptability!
Power diversification: it can be powered by gasoline engines and diesel engines, and single phase and three-phase power can be used as power.
Adapt to a wide range: the area is less than 1 m³, and the height can be controlled at about 2.6 meters. So it can be used in the field and indoors.
Practicality is wide: it can be used to drill the hole with auger stem, sampled with the core tube and drilled well.
It is small, and weight about 100kg. It is easy to carry and construction in a narrow space. It is suitable for investigation and drilling.
