……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:The advantages and disadvantages of the rotary drilling rig and impact drilling machine used in the construction of bridge bored pile foundation
Most of the hard rock formations have little pile diameter and are mostly end bearing piles. Most of them are made of impact drilling. Some of them are excavated by hand, and the small hole is short. The majority of bridge piles are impacted. Encountered complex formations, the pile length is less than 40 meters, the most reliable is the use of impact drilling. A look at geology, two to see the quality, or positive and negative cycle drilling, good quality of the hole, steel dragon protection layer can guarantee
Q:Rotary drilling rig is not a special equipment?
It is not a special equipment, it belongs to a pile machine
Q:What are the differences and relations between machine, trenchless drilling rig, horizontal directional drilling machine and rotary drilling rig?,
Drilling rigs include trenchless drilling rigs, horizontal directional drilling machines, rotary drilling rigs, long spiral drills, etc. are you ready to do the housing project? If you are planning to do the housing project, it is recommended that you use the full hydraulic long spiral rig, which is the trend, and now only one in Zhengzhou has the most mature ability to produce the rig,
Q:Rotarydiggingmachine life
Electronic equipment for 3 years. Note: construction machinery generally adopts the fast depreciation method, if your car does not recover the cost within 1-2 years, then you lose, and the later maintenance fee is definitely not a small number
Q:I love inventing super rotary drilling rigs. Can they dig wells? Can they move rocks? How deep can they hit?
Now, the rotary drilling will be replaced by the new double power wells drilled by the China shipping line
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:What's the market for small rotary drilling rigs? Do house foundations pile well?
With the changes of the times, the small-sized rotary digging machines are more and more accepted by the market. But every industry has risks and needs to be cautious. A certain market awareness is needed, and blindness will be futile.
Q:Does the rotary drilling rig require a national issued operating permit?
Of course, you need to go to the safety supervision department for processing, the cost is about one thousand yuan, the training fee is extra. My relatives have done a rotary drilling rig operation card, and now earn seven thousand or eight thousand pieces a month.
Q:Is there a need for slurry retaining wall for rotary drilling cast-in-place pile?
Dry rotary drilling, drilling, drilling into the hole do not need mud, there is water in the hole, it is easy to collapse. Therefore, dry rotary drilling does not require slurry wall protection. In the course of drilling, a wet mud wall is formed on the hole wall by drilling and extruding, and the mud is separated from the ground water.
Q:What is the market prospect of rotary drilling rig?
Domestic rotary drilling rig has a gap compared with foreign or domestic brands, there are 31 rivers, Futian, XCMG, etc., from the ability to see into the rock, in fact almost
