1. Rig has a long feeding stroke which can reduce the assistant time of adding drill rods and avoid block during the core drilling work. Thus, the efficiency will be advanced.

2. It has the long feeding stroke which is helpful to reduce the rod reversion frequency, avoid core block, and improve productivity

3. 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.

4. Operating is collected in one position, simple and convenient, flexible and reliable. It is unnecessary to have an extra slope drill tower when boring a slope hole. It can lift the drill rod in one time.

5. The chassis makes it possible to move conveniently and quickly. Thus, the preparing time can be enormously shortened.

6. The main hydraulic parts of the drilling rig, such as, the hydraulic pumps, hydraulic motors and quick links of the drilling rig are all selected from international famous products. Thus, the performance of the machine will be stable, creditable and long life.

7. The structure is in various forms, such as, skid mounted, trailer mounted and crawler mounted which are all available for customer to select. Skid mounted form has the advantages of easy removed, small size and light weight, so it assures good disassemblies, rapid and convenient installation and transportation, as well as lineate remote operation. Trailer and crawler mounted with great forms as a whole, can be removed and transported faster. Crawler one is also easily to move and flexibly to direct the location of the hole
