……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: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:Current situation of rotary drilling rig in China
In 1994, the Zhengzhou survey machinery factory introduced the production technology of the British BSP company's attached rotary drilling machine, but none of them formed mass production. 1992 Bauer company established a representative office in Beijing China, started their business in China. And in 1995 in Tianjin set up a wholly owned subsidiary of Tianjin Bauer Machinery Engineering Co. Ltd., assembled for Bauer BG20 rotary drilling rig market Chinese.In 1998, the Sino German joint venture, Shanghai Bao Jin Jintai construction machinery Limited by Share Ltd was set up in Shanghai, and the BG15 and BG24 rotary drilling machines were assembled and assembled. In 1998, XCMG began to develop and develop RD18 rotary drilling rig independently. It was successfully manufactured in 99 years and put into mass production. In recent years, China's rotary drilling rig has achieved rapid development. Later, Beijing Jingwei Juli 31 heavy machine, etc. have also involved in rotary drilling production, production of rotary digging drilling machine manufacturers at home and abroad has nearly twenty.
Q:How many litres of oil are usually consumed per hour in a rotary drilling rig?
This is not sure, depends on what type, and when the work is not full power work. +1And you work with the stratum is related, as far as I know, the intelligent drilling machine is still more fuel-efficient, 31, Zhonglian is also good
Q:What are the equipments used for bored pile construction?
Rotary drilling can be divided into positive circulation, rotary drilling, reverse circulation and rotary drilling. Its characteristic is that the slurry circulation is different, the mud is pressed into positive circulation, and the pumping mud is reverse circulation.It is suitable for the circulation of clay, silt, fine sand, and other types of soil; reverse circulation for cohesive soil, sandy soil, sand and gravel and weathered rock, but the pebble size shall not exceed the diameter of the drill pipe 2/3, and the content is not greater than 20%.
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: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 is the difference between punched pile and rotary pile?
Rotary pile generally refers to the pile type constructed by rotary drilling rig. It is called full blown bored pile, which is called rotary pile for short. Due to the use of mechanical work, the number of workers is not high, it can save a lot of labor costs
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:My rotary drilling rig has broken several rotary drilling pipes. Is it my drill pipe or the reason of my rig?
Hello, this is a lot of reasons, 1. may be man-made problems, 2. can also check the machine, 3. can check the drill pipe 4., to see if the geological suitability of your choice of drilling rod
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Mud: the mud of rotary drilling rig is made of mud while drilling, and more and more waste slurry is produced. The slurry of rotary drilling rig is made in advance, drilled and drilled again2: Mobile: rotary drilling machine, some mobile devices, and some walking style. Rotary drilling rig is tracked mobile
