Features:

1. This drilling rig is applicable to work in mountain, loess, hill, plain, forest,gobi,  seasonal farmland for seismic prospecting, mine survey, geologic framework investigation etc such drilling project.

2. Drilling method includes air drilling DTH hammer drilling, mud drilling, and casing drilling. Adapt to different drilling operation with relative drilling method. Max drilling depth is 30 meters.

3. Self-adaption system to stratum shortens handle regulating time of driller, improves drilling efficiency and ensure perpendicularity of the hole.

4. We design and use DTH hammer with interconvertible high-low frequency according to situation of single using DTH hammer (low frequency, big impacting energy) in prospecting drilling project nowadays. Choose high frequency matching parts of DTH hammer to improve drilling frequency when soft formation as f≤8.

5. Use lithium battery with big capacity to reduce weight at max limit.

6. New design of power swivel that circulation drilling fluid and bearing chamber are separate reduces damage probability of bearing.
