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's the difference between a long auger and a rotary drill?
1., first of all, the cost of machinery, screw digging more expensive than the long spiral.2. construction methods are not the same.3. long spiral diameter generally below 1 meters, 400mm, 500mm, 600mm more, common drilling depth is generally within 15 meters, -32 meters. More than 1 meters in diameter, you have to use rotary digging or other.4. long spiral applies to high-speed rail foundation construction, civil construction, rotary excavation in relatively large diameter foundation construction, such as bridge foundation construction is more common.
Q:What are the polymer slurries used for rotary drilling machines?
The polymer mud of rotary drilling rig is a kind of organic macromolecule material which is made up of anti collapse material, sediment treatment material and anti leakage agent. The earliest producers of polymer mud in China are CIS and Chennai, both of which are imported. The price is much higher than that of bentonite, and the dosage is much smaller
Q:31 What about the performance of the auger rig?
Domestic equipment is more than the price, preferential margin, financing efforts, sales services, after-sales service, and 31 in the price, preferential margin, pre-sales, after-sales service and so on are good.
Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?
Like other large machinery, can refer to the crawler crane, but the fuel consumption and artificial to determine, including other auxiliary drill wear, repair, drill tooth replacement, to see more big rig, for what geological construction.
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: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:Tire type rotary drilling rig, drilling depth of 15 meters, diameter 1.2. This machine is how much money.
I have been to the factory, and I can not say it is a lie. The equipment may be used in local geological conditions.
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?
Rotary drilling rig needs mud wall protection. Except in the middle weathered rock formations
Q:31 rotary drilling rig electromagnetic valve is what?
The solenoid valve is used to drive the valve core to control the direction of compressed air, so as to control the direction of the pneumatic actuator switch.Its advantage is simple operation, easy to realize remote control.
