I. General Description

DFQ series drilling rig is a kind of light weight, high efficiency and multi-function drilling equipment, it is suitable for drilling water wells, agricultural irrigation well, geothermal air-conditioning hole and other uses, especially for water engineering in mountainous and rock areas. It is much more efficient than the traditional rotary drilling rigs ,can create very considerable economic benefit for users. DFQ series drilling rig solves the problems to drill very hard rocks, gravel, pebble stratum that the traditional drilling rigs are difficult to drill, DFQ series can work efficiently under all kinds of geological structure.

III. Features:

1.The drill rig can drill different stratums, from soft soil to hard rocks,f=6~20.

2.Two rotary hydraulic motors with high torque, strong torque and adjustable rotating speed.

3. High pressure cylinders, supplying reliable propulsion and lifting force when drilling deep holes.

4.Innovative embedded idler pulley structure, we increase the carriage stroke (maximum to install 

4- meter drill pipe), very convenient for users to install and discharge pipes and the casings.

5. Four hydraulic stabilizer legs(can load 5 tons),increasing the stability at work.

They also enable the drill rig can automatically go up and down through hydraulic drive, the height can reach to 1.5 meters, easy for loading and unloading.

6. Two stages air inlet filter design ensures the service lives of diesel engine and air compressor in poor construction condition.

7. Centralized control of the hydraulic control console, convenient to operate. 

8. This drilling rig adopts excavator crawler chassis, strong cross-country ability and easy to transport.

9. With the composite locator, can adjust and change the positioning plate according to different drilling pipes and impacter, combining the horizontally automatic sliding function to ensure the hole positioning and centering more accurate and reliable.

10. We design the special drill pipe elevator instead of the traditional winch according to the practical user experience, more quick and easy to load and unload the drill pipes.

11. (Optional) Equipped with arc welding generator, convenient for on-site welding repair, providing the construction lighting at night.

12. Independent module design makes the drilling rig can be mounted on the truck, increasing its mobility.

13.Our factory can offerφ63.5,φ76,φ89,φ102,φ114 drill pipes,(special thick wall geological drill pipe STM - R780, material: 36 Mn2V, joint materials 35 CrMo thermal refining processing), according to user requirements can do surface nitriding treatment, in order to increase the wear resistance of drill pipes.
