1. Adopts the complete OEM Caterpillar retractable-crawler dedicated chasis,Its telescopic scope between the two crawler ends extends from 3000mm(at transportation) to 4400mm(at work). Undercarriage with expandable and removable tracks by means of hydraulic cylinders, guarantee exception stabbility in any type of ground. It has considerable traction force which allows easy movement even in the most difficult job sites.
2.Takes international top CAT Diesel engine with electric injection, turbocharged and air inter-cooling system. It is high reliability, fuel economy and power reserves. Emissions meet standard EPAC-Ⅲ.
3.The winches are positioned in the lower part of the mast, in front of the cabin, so that the operator can constantly check the proper operation. Thanks to the fact that the cable moves parallely to the mast, flection is not created on the upper part of the mast and operating life of the cable is therefore much longer. Tail positioned winch is available for heavy-duty type.
4.New design parallelogram system, computer optimized design and simplified pin connection system featured with nice appearance, great driving force and good stability, especially shaped to fit crowd system, allowing working radius adjustment always maintaining the mast in vertical position. The parallelogram system is easily for convenient transform between transportation and working conditions.
5.Self-erecting mast, high level anti-shock technology and high-strenth material steel attribute to that max torque can be applied all over the mast length. Multipurpose design for cylinder crowed system. Sensor and control center realize real-time measurement of the inclination angle, auto adjustment of mast verticality and inching adjustment.
6.Crowd system by means of long stroke hydraulic cylinder or crowd winch separately, are option for your exact request.
7.Rotary head with variable displacement motors and one high spin off speed. And rotary is extremely reliable, it has been disgned in order to gurantee a very compact, efficient and powerful rotary. The transmission group of rotary is made up of a hydraulic motor and new power shift purposely studied and designed to obtain maximum perfomance. During the drilling phase, the rotary has the entire power of the diesel at its complete disposal. Adapter of rotary is essential to absorb the considerable shock connected to the high speed of the main winch.
8.Telescopic kelly bar with guide made by high quality specially for high boring strength and torque force. Available with friction or inter-locking type.
9. All the main hydraulic components(pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, brevini, which ensure the stability, reliability, high-efficiency and energy-saving of the entire system
10.Electronic controlling system is an innovative system, developed by Osaint, which controls and monitors the operation of the machines. For ease of operation, the system is controlled by a touch screen located in the cab. The system function is to enable the machines to perform different functions more efficiently. A dedicated power module electronic control and CAN-Bus system ensures the main pumps and Disel engine to work at their most effective and productive stages.

Q:Various types of rotary digging drill rod head size
Rotary drilling rig in China as long as the same type of drill head size is the same, such as 22 and 31 of the 22 rivers square is the same size
Q:In the middle of the 220 rotary drilling rig, sometimes the drill pipe slipped down 5~6 meters at work, as if the rope was broken. What's the matter?
The first is when the card drill rod, then the clamping rod parts will appear suddenly from the above phenomenon. Generally, the drill rod is worn out, and the biggest damage to the rod is the power head and the steel wire rope.
Q:How much is a drill bit?
The price depends on what kind of drill bits are used, such as spiral drill, bucket drill, open and close drill, rock core drill, etc.
Q:What are the polymer slurries used for rotary drilling machines?
Polymer polymer mud is a kind of advanced foreign technology imported product. It is a kind of water soluble and easy mixed powder granule polymer
Q:Are our common rotary drilling rigs the same as those for well drilling machines?
No, rotary drilling rigs are used for foundation piling
Q:Rotary drilling rig new steel rope appeared a strand of steel wire, what is the reason for the stock?
A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment preferred anti galvanized - phosphorus corrosion prominent double coated steel wire rope.
Q:What material steel pipe do the drill pipe use?
API standard E75 to S135 steel grade, outside diameter from 2 3/8 to 6 5/8 series of oil drilling rod and high torque resistance of double shoulder joint drill pipe and BNK C95S drill rod for special steel grade used in sour oil well. It is mainly suitable for the construction of deep well, horizontal well and large displacement well during the exploration and development of oil and gas.
Q:The difference between rotary drilling machine and rotary machine.
The driving modes are different: the rotary drilling rig operates the drill rod through the rotary table, while the rotary drilling rig is operated by the power head to drive the drill pipe.
Q:Why is the rotary drilling rig put into the steel cage before pouring?
When pouring concrete to the reinforcement cage, if this time to improve the catheter, catheter at the bottom of the reinforcement cage distance is only about 1m distance, due to pouring concrete pipe after homing large impact force, promote the rebar cage floating;
Q:Which is faster, the reverse circulation rig or the rotary drill?
The place is different. There is no comparability.The engineering process is different and the drilling rig model is different!
