……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:Attention problems of rotary drilling rig
Lubrication of Slewing Support racewayThe slewing support roller shall be filled with grease once every 100 hours. Under special working conditions, such as tropical, humidity, dust, temperature difference and continuous operation, the lubrication cycle should be shortened. A new grease must be added before and after the machine stops running for a long time. Grease the grease before injecting grease. Each lubrication must be filled with grease in the raceway until it oozes from the seal. When grease is injected, turn the slewing ring slowly.
Q:How can the drilling rod of rotary drilling rig be telescopic?
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.
Q:What are the advantages and disadvantages of the construction of the bored pile with auger and rotary drilling? Another auger can drill 1800 diameter piles?
Suitable for a variety of spiral drilling geological layer, and the hole diameter can reach 3.5 meters (I did at the start of 90s); rotary drilling rig only for certain efficiency with gravel clay layer or work, but for the rock layer, sand layer is not; and rotary drilling rig can not drill deep hole (more than 30 meters deep is more difficult).
Q:31 rotary drilling rig, 280 pairs of steel wire rope, how long?
This problem is best advised to equipment manufacturers, they have after-sales service team, can ensure the accuracy of the answer.
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
Hole air quality, hole wall quality, water gushing, quicksand and other geological conditions, orifice protection, safety protection inside and outside the personnel hole, mechanical equipment operation conditions, probably on these, one, a good grasp on the fine.
Q:Why not use rotary drilling rig instead of manual digging pile?
Rotary drilling rig deviation is too large, the basic holes are straight, and drill down to the following oblique error is great
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:Rotary drilling rig GPS unlock?
Yes, there are pumps, trucks, mixing stations, auger rigs, crawler cranes, GPS unlocks
Q:Rexroth leveling sensor rotarydrilling rig
Solar term door position sensorRole: throttle position sensor is to monitor the throttle angle of opening size, determine idle speed, full load and acceleration and deceleration conditions to implement and throttle opening stateCorresponding fuel injection control. Failure effect: idle speed is high or low, or cause runaway phenomenon.
