Usage scope
1. it is applicable to prospecting and exploration, geophysical exploration, road and building exploration, and drilling works such as boring and blasting and various concrete inspection holes.
2. it adopts different drilling bits to so drilling works for different stratums ,such as diamond, alloy, steel shot, and steel drop drilling bits.
3. it can be used to drill 2-9 class sandy clay and basement strata.
4. when the finial hole diameter is 75mm, the rated drilling depth is 250m and the maximum depth shall not exceed 1.1 times the rated depth. The rated opening diameter is 110m and the allowable maximum opening diameter is 150mm.
Features
1. with oil pressure automatic feed mechanism, it can improve drilling efficiency and reduce workers' physical work.
2. it adopts ball cassette clip to replace chuck and can perform non-stop rod reversing. It is easy to operate ,safe and reliable.
3. a pressure gauge is equipped at the bottom of a hole to grasp the condition of the hole.
4. the centralized handle is easy to operate and easy to maintain.
5. compact structure: drilling rig, pump and diesel engine are on the same base.
6. light weight and easy decomposition to quick to move, so it is applicable to plains and mountainous areas.
