……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:How many piles per day can the bored pile foundation be 400mm and the pile is 25 meters long?
1 、 impact drilling hole: adapt to relatively soft formation.2, rotating drilling hole: adapt to relatively hard strata or gravel layer, backfill and other complex geological conditions.3. Hole drilling of casing drilling machine: it is suitable for stratum with flowing sand and underground water.4. Drilling by rotary drilling machine5. Drilling under karst geological conditions6, reinforced cage, concrete7 、 deepwater drilling pile fixed platform
Q:Is the rotary drilling rig driven by electricity?
Each hydraulic motor of the redistribution works again. As for the power of rotary drilling, power generation is usually realized by the dynamo driven by the internal combustion engine. So. Generally, the rotary drilling rig I saw does not need an external power supply. But it is inconceivable that a bit of electricity can be found on the auger rig.
Q:Hole drilling price of rotary drilling machine
The geological conditions of deep hole depth into the empty aperture method whether it contains steel cage contains reinforced cage contains concrete auxiliary equipment whether party a gas station how to calculate the construction of reasonable charge pile head break
Q:What is the drilling speed of rotary drilling machine?
If you want to set a constant need for advance, the principle of servo rotary drilling, drilling efficiency and main pressure and bottom friction. It is no use adding pressure to the friction bar, which is only related to the critical value of the sliding friction force acting on the drill pipe. With this principle, torque and pressure servo can be achieved. Achieve optimum drilling efficiency, especially in soft formations.
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?
About partial holes, holes in the deeper, the probability of partial hole is bigger, so the rotary drilling rig is generally shallow excavation, not many partial holes, and the spiral drill can generally be deep drilling, there are partial hole phenomenon, especially in the condition of non-uniform strata.
Q:How can we not drill the rod and drill the rod?
Common causes1. There is a foreign object between the sections of the drill pipe.2, pressure surface wear, curling.3. Bending or deformation of drill pipe.4, the drill scraping hole wall, machine lock rod part into the lock.5, inclined hole.
Q:Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
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. It extends in the first order, the next second, and then the third, the last, the fourth, and the fifth. During drilling, it is stretched by gravity and bit by bit with the drilling depth. Rotary drilling rig in the multi-functional areas to improve, and it is not necessary to complex conversion can be converted to another device, it is worth studying.
Q:The best domestic rotary drilling rig, steel wire rope manufacturer
At present, the domestic and foreign rotary drilling rigs are not equipped with moving pulleys, so the tension of the single rope of the steel wire rope is larger.
Q:How can the rotary drilling rig not be pulled out of the ground?
What you describe is not very thin, but the long retaining cylinder, pumping, excavation, lifting (large crane or Jack) is a common method
Q:What are the sizes and sizes of common drilling rigs?
Theoretically, how big holes are needed for construction, and how large the drill bits are. The common basic 200, one unit, 600800, and 160018001500 are also available... The big one is 25002800
