Durable Soil Core Test Drilling Machine for Small Bore Well Drilling
Durable Soil Core Test Drilling Machine for Small Bore Well Drilling
Product Features:
1) This rig applies to general survey exploration and, geo-exploration, road and building exploration, shothole drill and the drill of inspection hole of concrete structures.
(2) Selects different drill bit of diamond, alloy or steel grit according to the stratum.
(3) Drills in loams and base rock layers of two to nine grades.
2. Features of rig
(1) The rig has oil-pressure actuating system to improve drilling efficiency and reduces the workers’ physical labor.
(2) Uses ball joint instead of chunk to back the lever conveniently and safely without stopping machines.
(3) It has a manometer to show the pressure in the hole.
(4) Operated conveniently as the handles are centralized.
(5) It has compact structure, as rigs, pumps and diesel engines are on one pedestal so that save the space.
(6) Suitable to work on the plain and mountainous areas for it is moved easily with lightweight and simple to disassemble.
