……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:How is the construction of rotary drilling and piling machine built on the floor?
Use the mud pump to bring out the earth which is drilled, form a pile hole, then lower the steel cage and pour the concrete.
Q:Why should auger drilling be done by means of jump excavation?
It is too tight, easy to punch through two holes, and after the hole into the cage, and filling, next to hit, you can not fill.. Hope to adopt
Q:There are several brands of rotarydiggingmachine
Hitachi: Japanese brands, excavator sales is also very big, general can also assemble. (HITACH)Advantages: mechanical matching in general, hydraulic systems in general, flexible movements, generally durable, maintain value in general, the use of cost in general, fuel consumption in general, the strength of the middle, the price is about 3-5 cheaper than komatsu.Disadvantages: not durable, more, after two or three years of serious oil spill, mainly high water temperature or hydraulic system, the No. 20 machine for four missing engine, it is to increase the displacement of the lack of strength reduction, not dare to use, the general price of second-hand car.Kobelco: Japanese brands, sales of large, general can also be assembled. (KOBELCO)Advantages: down payment, fuel-efficient. Good color.Shortcomings; not strong, durable, four cylinder diesel engine overhaul after a very poor quality, only dry earth live, because does not have the strength, is certainly not good for put all sorts of things together.Volvo: good brand, big sales, good reputation, the overall good, assembled. (VOLVO)Advantages: good safety performance, luxury. Fuel efficient and fast.Disadvantages: Volvo new machine can be, but domestic serious, more fragile, not enough thick, two mobile phone price is low, not good sell.Doosan: Korean brand, integrated more moderate, imported machines are low grade products, assembled. (DOOSAN)Advantages: low price, -8 series low fuel consumption. All kinds of projects are available.Disadvantages: the product quality is lower than the average price, moderate price, moderate quality, and poor after-sale. Low inflation.
Q:Does the rotary drilling rig need mud?
It needs mud and wall protection, and there are certain standards.
Q:How long is the auger type 360?
The drill rod of the rotary drilling machine is now extended from the lower part of the hoist, the steel wire extends out, and the hoisting rope is retracted. But some rotary drills can be extended either by a crane or by gravity.
Q:200 rig footage every day how many meters
What stratum? What about piles? Full sticky mud, 1 meters, 60 meters deep, up to 3 hours a, fastest 2 hours,
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:The relationship between rotary drilling and impact drilling and reverse circulation drilling
Positive and negative cycle is another process, which is used to break the soil into small particles or mud, and the positive circulation is to use the pipeline to drill into the drilling site, and the orifice is discharged. Reverse circulation is drilling site pumping, orifice grouting. It can be used either as a roundabout or as an impact. Impact is the use of heavy hammer or DTH hammer broken soil, mostly mostly using positive cycle process.
Q:Do you need electricity for rotary drilling rig?
Generally do not use electricity, the use of the rig itself diesel engine power.
Q:If you have a project, will you make money from the auger rig?
That depends on the length of time and geological reports, ah, generally better early, and if not done, it is best to make a commission
