Hd-40a Portable Drilling Rig For Works On Mountains

We are engaged in manufacturing, exporting and supplying HD-40A Portable Drilling Rig For Works On Mountains in Zhuozhou, Hebei, China.
1. Drilling method includes air drilling DTH hammer drilling, mud drilling, and casing drilling (With casing puller). Adapt to different drilling operation with relative drilling method. Max drilling depth is 40 meters.
2. 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.
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 inter convertible 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 fAcA A 8.
