……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 brand of rotary drilling rig quality is better? How much? How long is it back?
From the quality, Bauer, but, force big foreign soil is definitely one of the king, started early, mature technology, excellent quality, engineering absolute peace of mind. The only drawback is that compared to the domestic situation, the price is too high, almost the same level of domestic drilling rig 1 - 2 times. Although the quality of the excellent, but considering the initial investment, back to the time and other factors, most customers are discouraged. The same model, Bao goose can sell 700W-800W, but domestic brands only need 400W or so, although the quality is higher, but the price is difficult to accept. Therefore, it is recommended that you do not recommend investing in these brands unless you have substantial funds.
Q:What's the minimum cost of a rotary drill? How much is it?
Rotary drilling rig rental prices last year at this time, about 220 is 14~16, in case of a month
Q:What is the minimum diameter of a bored pile?
According to the regulations of rotary drilling and grouting pile operation regulations, the minimum diameter of rotary bored pile is 670mm, the drill bit diameter is 600mm, and the actual drilling hole is 670mm.
Q:Working life of rotary drilling rig
The number of total construction meters you have no way to answer, one day a rotary drilling stem two, three hundred meters to tens of meters are met, the weather situation of non visible suspension, or because of the project department, such as the human shutdown can avoid has probably worthwhile. There is no average monthly number of meters.
Q:31 What about the performance of the auger rig?
Domestic equipment is more than the price, preferential margin, financing efforts, sales services, after-sales service, and 31 in the price, preferential margin, pre-sales, after-sales service and so on are good.
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 brand is good for rotary drilling machine?
About aftermarket. CSR mainly rely on after-sales service and Caterpillar after-sales system. Zhonglian, 31, Xugong are their own aftermarket forces. Of course。 Many of the Carter chassis are Caterpillar's men. 31 aftermarket system in mid 2011 last year. Some relaxation. A lot of people ran (I was in Beijing). Many of my friends have gone, the specific reason seems to be 31 restructuring. So at this stage do not superstition 31 aftermarket. A lot of people are new people.
Q:When the rotary drilling rig is working, how does the rotated soil enter into the slag bucket?
Rotary drilling machine is also called drilling bucket drilling method, short spiral drill bit and other operating device for dry and wet drilling, and the use of rotary digging, successive soil sampling, repeated cycle operation and drilling as the basic function of the drilling machine. The rig can also be equipped with long spiral drilling, casing, and drive device, pedestal drilling bucket and auxiliary device, underground continuous wall grab, precast pile hammer device, rotary drilling rig main parts from site and working device, rotary drilling rig in enter the working state, the control system through the luffing mechanism of mast angle adjustment the mast and leveling, is able to drill vertical drilling, the power head provides torque to the drill pipe and the drill bit to do rotary cutting; and pressurized cylinder to drill pipe and drill through the power head transmission pressure, pressure to achieve drilling bit, when filled with muck, the main hoisting drilling bit left, turning to a certain host open angle drill bottom door, close to Doumen, full of muck, back drilling locations, decentralization of drill pipe, the drill hole drilled into again
Q:How can the drill pipe cracking of rotary drilling rig be welded?
Tell you, you remember, it's a friction welded joint! If it is not friction welding, it is deceptive. Because the oil drill pipe is friction welded. There is a welding and cutting equipment company in Harbin. I used to work as a technician there. Can help you with this problem.
Q:For different geological conditions, how to choose rotary drilling, rotary drilling, impact drilling?
Rotary excavation is often used in the excavation of cohesive and sandy soil layers, but the efficiency is relatively high. But for rock foundation excavation, the requirements for rotary excavation equipment, especially the requirements of drilling bit and drilling rig, are very large.
