……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:Can the auger drill be drilled into the two - longest granite of the 1200kp?
Drill the special effort, we have the hardest to 900kp, take the drill, hold up, are a large column, an hour about 2 meters into the rock. Hard, then the hole time is very long, slowly grinding.
Q:200 price of rotary drilling rig
As far as ordinary strata are concerned. Domestic product is ok. If only the strata were rather complicated. Even imported rotary excavation. The price of the project department. You may not be able to do it.
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Such a soil condition, it is not recommended to use rotary drilling rig. The upper soil can be drilled with a rotary drill, and an impact drill can be used after the formation of rock.
Q:Various types of rotary digging drill rod head size
Because the rotary digging into the sea China earlier, there is no uniform B by national standard, but the host plant is basically the same, but the difference is mainly divided into two types of schools: as schools, using standard rotary drilling chassis, the stability is good; 31 schools, using the general excavator chassis, stability has been lacking, but saves cost
Q:The structure and principle of hydraulic rotary drilling rig are discussed!
Hydraulic and electrical should be explained on the spot. It's not good to explain to youConclusion: to know the hydraulic rotary drill movements, each action is respectively connected with the two pipes into one, you can get ahead from, the following are some pilot valve block and control the small tube, you can find the back from the cab, find the valve block. Look, where are the controls? Don't see so many pipes.Electrical is also very simple, the electrical cabinet is the core, but also divided into several blocks, divided into several major areas, the decomposition of control on the line.
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: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 to choose the drill bit of a spiral drill?
Long spiral drilling machine as a construction machinery is often used in a device, the utilization rate will not be less. Long auger drill has a wide range of application, and can meet the needs of bridge construction and high-rise building engineering. At present, rotary drilling rig has been widely used in drilling and grouting projects. For long auger rig operators, requirements are very strict, before the operation can not drink, take medicine, etc., which affect the normal operation of long spiral drill, all can not do.
Q:What kind of stratum is suitable for rotary digging pile?
Short spiral drilling tools are applicable to cohesive soil, silt, earth fill, moderately dense sand and weathered rock formations above the water table.
Q:Is the rotary drilling rig driven by electricity?
Each hydraulic motor of the redistribution works again. As for the power of rotary drilling, power generation is usually realized by the dynamo driven by the internal combustion engine. So. Generally, the rotary drilling rig I saw does not need an external power supply. But it is inconceivable that a bit of electricity can be found on the auger rig.
