Application of GK-200 hydraulic diamond core drilling rig :
This borehole drilling machine is mainly used for Geological survey and exploration, basic exploration for roads and high-rise buildings, inspection holes for various concrete structures, river embankments, subgrade grouting holes, direct grouting, civil wells and ground temperature central air conditioners.
Advantages of GK-200 hydraulic diamond core drilling rig :
1,hydraulic control system ,easy to operate
2,diesel engine power ,convenient to use ,special in no electric and faraway area
3,two wheels mounted ,can be trailed by pickup truck or tractor ,easy to move to any place
4,can Drill on soil, sand, gravel, thickhard rocks, marble, and any other hard ground, etc.
5,Mainly used for water well drilling for farm /industry irrigating, Soil test, SPT Test ,earth sample taking, Geo-technical exploration, ground survey, etc.
6,Keeping bracket is installed on the hoist to form a double wheel support structure, can withstand strong blow.
7,,Vertical box four couple of bearings positioned to ensure the rotary machine has a sufficient rigid response to gravel layer ,the complex geological conditions.
8,This bore drilling machine adopts national patent technology taper clutch, with characteristics of strong transmission torque, easy to operation, free to maintenance.
9,53x59 driving lever is adopted, high rigidity, strong delivery torque.
