……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:Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
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. It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
Q:What are the differences and relations between machine, trenchless drilling rig, horizontal directional drilling machine and rotary drilling rig?,
Horizontal directional drilling machine belongs to trenchless drilling rig. Horizontal directional drilling rig is a trenchless pipeline laying equipment for communication, electric power, gas, tap water, rainwater, sewage, heat, chemical and other industries.
Q:What's the difference between the main oil pump imported from the rotary drilling rig and the home made main pump?
The rotary drilling rig has two winches, one main hoist and one auxiliary winding, wherein the auxiliary winding is of some auxiliary function, such as hanging a protecting cylinder or something, and the main hoist is used for lifting the drill pipe.
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.
Q:How much do you charge for a day rig?
Also, if you rent the rig, you must request a drill safety certificate, and the operator's operation certificate, you must carefully check, because there are more false. If there is no test of engineering equipment, a safety accident, you have to bear responsibility.
Q:Which rotary drilling rig is durable and economical?
With FR622D FR620D, leiwo, comfortable operation, strong ability in rock.
Q:What bucket teeth are used in rotary drilling machines?
We use the site above alloy bucket tooth, tooth special rotary drilling rig alloy, durable many times more than ordinary tooth Oh, but the price is several times more expensive than ordinary, but together, but it is still very good, after all, little change in time, save a lot of trouble.
Q:Rotary drilling rig new steel rope appeared a strand of steel wire, what is the reason for the stock?
A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment preferred anti galvanized - phosphorus corrosion prominent double coated steel wire rope.
Q:220 rotary drilling rig can adapt to what kind of soil?
Mainly suitable for sand, clay, silty soil layer construction, bored pile, continuous wall, foundation reinforcement has been widely used in various foundation foundation construction, the rated power of rotary drilling rig is 125 ~ 450kW, the power output torque of 120 ~ 400kN / m, the maximum diameter of Kong Zhi is 1.5 to 4m. The maximum hole depth is 60 ~ 90m, can meet the requirements of all kinds of large-scale infrastructure construction.
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
English is rotary drilling rotary drill rig, in addition to the configuration of various rotary bucket operation, installation of casing drilling, with rolling tube device and grab for will casing construction; with telescopic guide rod grab underground continuous wall construction, with DTH of hard rock crushing construction; operation device can also be replaced for jet construction and circulation of construction; construction of pile foundation can also configure other forms of hydraulic hammer, diesel hammer etc..
