……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: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:How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
The bored pile foundation is capable of hitting 20 piles with a pile diameter of 25 meters a day and a pile length of 400mm meters
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:There are several brands of rotarydiggingmachine
Let's say a joint venture brandCaterpillar: American brand, old brand, independent production. (CAT)Advantages: full strength, durable, strong, not easy to bad.Disadvantages: high price, high fuel consumption, short arm, small work range. Especially mine type models, large fuel consumption, after-sales service in general.Komatsu: Japan brand, excavator industry leader, the total cost-effective, independent production. (KOMATSU)Advantages: better strength, strong and durable, low fuel consumption, hydraulic pressure is its strong point, the overall coordination is good, the speed is very fast, not easy to bad, good hedge, used car good shot.Disadvantages: high prices, accessories expensive. (Note: because of its high share in China, the sub factory has many parts, so it is cheaper.)
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:What kind of stratum is suitable for rotary digging pile?
Core auger bit is suitable for crushed stone soil, medium hardness rock and weathered rock formation. Core rotary bucket, applicable to weathered rock and cracked rock.
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
Cyclotron is used drilling mud circulation way out of the mud, in the form of power head of rotary drilling, using powerful torque directly to the soil or gravel and other rotary drilling waste slag mining, and then use the spin bucket hole is put forward quickly out of dry soil.
Q:How about the collapse of rotary drilling machine?
Drill rig is mechanical equipment for drill holes on the surface, can be a large outdoor wells, oil and gas well drilling equipment, small equipment or single movable, called spiral drill. The drilling rig can take samples of underground mineral deposits, or for underground production facilities such as underground machines, instruments, pipes and wells. It is a mobile device mounted on the truck, trailer, track, or is fixed on land and offshore structures (such as drilling platform, generally referred to as the "offshore oil rig", although the design does not contain a drill).
Q:Working life of rotary drilling rig
Rotary excavation life with maintenance, operation, construction geology, pile diameter have a great relationship.Maintenance needless to say, a little common sense of all know.Operation is like adults with children, teach good, just do not learn well, it is waste.The quality of construction geology is also very critical. Just like the 60 year old man, called him one night and three young woman gas Wang ML, certainly fall apart!Pile diameter size and depth: for example, type 220 rotary excavation, the maximum theory is 2 meters 5, depth of 65 meters. But it's really hard to reach. The geology is good. 2 meters will be enough. If you really do 2 meters 5 of the pile, it is like a night can only do 3 times, I'm going to do 5 times, 7 times.
Q:Rotary drilling rig GPS unlock?
This method is actually the simplest one for most Android phones. Before the operation, you only need to shut down mobile phone, and then press the volume + or - when rebooting (different brand mobile phone may differ), while holding down the power button, you can enter the Recovery mode. Go to Recovery mode and select Restore factory.
