Feature&Technology

1. With large impact energy in the top drive drilling head, that can achieve impacting drilling without using DTH hammer and air compressor, has higher working efficiency and better result.
2. With omnidirectional, multi-angle adjustment, which can meet many kinds of drilling angle requirement, more convenient for adjustment.
3. The impact energy transmit on drilling tools from inside to outside, which reduce drill sticking, hole collapsing, drill bit being buried or other incidents, and make the construction safer and with lower cost.
4. With large torque, high rotary speed, large impact energy, that makes this machine able to applied in wider soil layers, especially in sandy gravel layer, crushed rock layer, stone soil, sandy layer, and other easily collapsing layer that need impact drilling. It has high efficiency of drilling speed and high quality of hole. When the water content is too high in the layer, in this case, the DTH hammer is not working, and the technology this machine process becomes the only choice.
5. With movable console, which is easy to operate and convenient for operators to view the drilling hole.
6. This machine is mainly applied in: foundation supporting, slope supporting, micro piling drilling, tunnel shied, and many kinds of hole guiding construction, and other engineering.
