Surface Core Machine Core Drill Rig High Rotary Speed A Felicitous Speed Range
YDX-800 drilling rig is mainly used in diameter diamond drilling of metal and nonmetal solid deposit exploration. It can also be used in carbide bit core drilling. It is used to bore vertical holes as well as inclined holes, which is also applied in engineering boreholes of hydrology water wells, petroleum or gas field exploration, dike & dam cement grouting, tunnel ventilation and water draining, etc.
YDX-800 Core Drilling Rig, which is one kind of full hydraulic drive power head model drilling rig, it takes advantage in its high rotary speed, reasonable rotary speed range, various rotary speed grades and big torque in low speed. Hence, it’s very suitable for small diameter diamond bit core drilling. Meanwhile, it can meet the requirements of large diameter carbide bit core drilling and varieties of engineering boreholes.
It has a long stroke which is helpful to reduce the rod reversion frequency, avoid coring block, and improve productivity,It has a simple structure, a light weight and is convenient to remove, so as to make the replacement process easily.
Its operation is concentrated, simple, convenient, flexible and reliable, so as to reduce the labor intensity a lot.

1. Full hydraulic control, convenient and flexible operation, convenient shifting, good ability, saving time and effort.
2. Machine has a higher rotary speed and a felicitous speed range which has multi steps and large torque in low speed. It can be applied for small diamond bit core drilling, satisfied for the large diameter carbide bit core drilling and so on.
3. It is no necessary to have a slope tower when drilling a slope hole. It can lift the drill rod in one time.
4. The track or crawler chassis make it possible to move by oneself. It is so convenient and quick that the preparing time can be enormously shortened.
5. All the equipments of this rig are installed on chassis droved by diesel power engine.
