……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 new steel rope appeared a strand of steel wire, what is the reason for the stock?
There is no wire rope live picture, it is difficult to analyze what causes it. It is possible that the multi strand resistant rotating steel wire rope has been separated from the inside and outside ply ropes, and it may also be the separation of the inner and outer ply ropes caused by the bending deformation. Cheap no good goods, good goods are not cheap, perhaps encountered inferior steel rope, and small steel rope factory may be an engineer also did not rely on cheap hit the market, the quality of worrying.
Q:What kind of hydraulic oil is used in XCMG XR220 rotary drilling rig?
Rotarydiggingmachine fever is a normal phenomenon, but if serious account of hydraulic oil filter through the difference, the best choice for Shell Tellus s2m46 oil
Q:What drills are used to drill the hard layer of the rotary drilling machine?
I want to know how thick and big the pebbles are in you. Strong, weak, weathered, with double door fishing sand drill (pick teeth) can
Q:Rotary drilling rig on the floor under the floor with steps
The front mast, the drill mast, is upside down. Pour down and drive up.. As for the range of attention, what?.... I can only tell you, without master's instructions.. Very dangerous...
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
Cyclotron is used drilling mud circulation way out of the mud, in the form of power head of rotary drilling, using powerful torque directly to the soil or gravel and other rotary drilling waste slag mining, and then use the spin bucket hole is put forward quickly out of dry soil.
Q:Why not use rotary drilling rig instead of manual digging pile?
It is time the project team in general when digging and construction engineering team can.
Q:What bucket teeth are used in rotary drilling machines?
Rotary drilling machine selection bucket teeth must select special rotary drilling machine bucket teeth, after all, in the ground tens of meters, can not be like excavators, to spin wear-resistant
Q:Rotary drilling rig is not a special equipment?
Pile construction machinery: in all kinds of pile foundation construction, used for drilling, piling, and piling machinery, collectively referred to as pile construction machinery. Generally, the piling machine is composed of two parts, the pile hammer and the pile support. In addition to the special pile stand, the pile rack can be arranged on the excavator or in the machine, and the piling task is completed. The main characteristics of pile construction machinery are its strong specificity and small batch production
Q:How many types of rotary drilling rigs should be used for entering ten meters of weathered sandstone in the rock?
The current domestic rotary drilling rig manufacturers and models are more well-known manufacturers are mainly ZOOMLION, 31 heavy machine, Xugong, CSR, Futian, Shanghai Kim, Tianjin sunward, Bauer, Wujiang geotechnical, Yutong, mainstream rock into the rotary drilling rig has 31 main SR280R into the rock rotary drilling rig, Zoomlion ZR280 360, Xugong, Bauer BG25 into the rock can be, but the price is not high, 31 C8 series rotary recently to participate in the 2014 Shanghai BMW exhibition drill SR285RC8/SR385RC8, is said to have ability to exceed the traditional rock entering into the rock type rotary drilling rig.
Q:What is the difference between punched pile and rotary pile?
Punching pile is the impact of heavy hammer falling, the soil or rock to disperse or break, and then floating through the mud of these debris floating, and then pumping, the pile side of the soil compaction, I think it can be ignored. Punching piles are usually rock - in. They just break the rock and squeeze it out.
