    Working site:     Various models of DFQ series                                        FAQ   How to choose a suitable drilling rig? 1. What will you do using drilling rig?  ---For water project, core sample, soil test, mineral prospect or others? 2. The depth you need? ---For water well, generally, 30-200m. For core sample, 30-600m, even more.  3. Any requirements to hole diameter? ---Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional. 4. Working land condition? A. soil, sand, weathered land, etc. soft stratum. B. soil, sand, soft and hard rock stratum, mixed one.  C. Mainly hard rock, like granite.   Based on the above information, experienced engineers will help you recommend suitable machine and price.
