……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:200 price of rotary drilling rig
According to geological conditions and work content to determine the unit price, generally 200 yuan / meter
Q:What are the polymer slurries used for rotary drilling machines?
Polymer polymer mud is a kind of advanced foreign technology imported product. It is a kind of water soluble and easy mixed powder granule polymer
Q:The Montreal rotary drilling mud powder special effect is good
The Montreal chemical slurry quality.Zhengzhou 107 road viaduct construction are used in Montreal chemical slurry! Good shelter and little sediment.
Q:How heavy is the 250 auger rig?
There is a SR360 rotary rig, the largest 200 ton rig in Asia
Q:What are the components of rotary drilling rig Jixietaiban? How to calculate?
This contract according to the geology and site conditions have different changes, according to a 24 hour standard, a drill, a crane, a forklift, each driver two, a site manager, coolie four, perfusion six, a welder, purchasing a drill, water pump and other auxiliary vessel some general tools, according to the size of pile, geological conditions of pricing, how much money per meter.
Q:How to distinguish the performance of rotary drilling rig?
1. first of all, from the drilling equipment, the configuration of the drill rod to determine;2., from the special chassis to distinguish, its special get off, crawler frame using retractable structure, whether to solve the highway transport laws and regulations on the width of the machine requirements, and improve the whole machine in construction reliability and stability.3., followed by EFI turbocharged, cold engine, with high reliability, fuel economy and high reserve power is better. Computer induced load changes, direct injection electronically controlled fuel injection to provide accurate fuel injection, to ensure strong power and economic fuel consumption.
Q:How can the drill pipe cracking of rotary drilling rig be welded?
Or very good welding, and see what the substrate material. The shaft fracture can be welded. Tianjin source welding can be consulted.
Q:Kim Taixuan drilling operations and other brands of rotary drilling operation do.
Kim said the truth than other manufacturers of machine operation is relatively simple, because the machine is Kim hydromechatronics, many other manufacturers to operate the machines are easy, and the construction efficiency is relatively high in similar products.
Q:What happened to the black smoke from the exhaust pipe of the rotary drilling rig?
Check whether the leak valve pressure cylinder deposit or combustion chamber or carbon 5, check valve check check the ignition advance or deviation ratio consult step related service station for inspection on automobile exhaust smoke introduced hope you help the original wish you a car.
Q:Xugong 220 rotary drilling rig operation instructions who help find
Foreign productsJoint development and production of rotary drilling rig mainly Bauer (BAUER), and force (SOILMEC), (IMT), Matt imgai (MAIT), Casa Grant, (CASAGRANDE), DELMAG, MGAF, Haier and Hitachi, Ingersoll Rand, Bohai - Sumitomo company. The main products are shown in table 1.
