……More info  


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:Why should auger drilling be done by means of jump excavation?
According to the construction of regional geological conditions and construction requirements, the general pile drilling pile construction in the jump, has been filling into a pile of adjacent pile drilling bit, is to wait until the strength of concrete bored pile has reached more than 2.5MPa before drilling, to avoid the disturbance of bored pile adjacent construction.
Q:What kind of geology is a rotary drill suitable for?
Is a rotary drill hole construction process operation for building foundation engineering. Widely used in construction engineering to municipal infrastructure construction, highway bridges and high-rise buildings, with different tools, suitable for dry (short spiral),
Q:What kind of rotary drill rig is it?
Yes, and now, Hunan has bought a Matlock
Q:There are several brands of rotarydiggingmachine
Hyundai: Korean brand, but it is low-end goods, assembled. (HYUNDAI)Advantages: cheaper prices, good parts to buy, cheap.Disadvantages: machines can't even reach the standard of domestic machines, either good or bad.Personal view: imported brands can only buy more than these brands, Keith (CASE), JCB (JCB), Kato (KATO), Terex (TEREX), Bohai Seoul (LIEBHER), Sumitomo (SUMITOMO), Ishikawa Shima (IHI), Kubota (KUBATO), Takeuchi (TAKEUCHI) are not allowed to buy. Low share, customer service service points less, difficult to buy accessories, if you buy, there will always be these problems.Komatsu and Carter belong to the independent production brand, the primary consideration
Q:200 price of rotary drilling rig
According to the brand and the place of origin is not the same. The price is different. Pure imports are more expensive than imported drugs.Imports are more expensive to assemble than domestic ones.
Q:XCMG XR360 rotary drilling rig generally how much?
5 million 700 thousand standard 508 drill pipe, section five 77 or four Mimo resistance pipe, section 62 meters machine lock, two optional one
Q:Are our common rotary drilling rigs the same as those for well drilling machines?
A dozen meters of drilling hole, is to drink water, drink water to break the stone, no stone rig also never mind, in Loess
Q:How high are auger rigs and impact drills?
Rotary drilling rig upright, 20 meters to 28 meters, the more high, about 3.5 meters high transport status.
Q:How about the speed of rotary drilling rig?
Not at all. It depends on how you do the work.
Q:What is the lifting force of the main hoist of a rotary drilling rig?
Under normal circumstances the main hoist is responsible for the drill pipe and the drill bit weight can be, but when the drill will be mud suction and pore wall friction in the air, so the main hoist lifting force of the drill bit and is generally greater than the gravity, sometimes if there are some things above the pressure in the collapse of the drill rod can better reflect the main hoist lift characteristics.
