……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 are the reasons for partial drilling of rotary drilling machine?
Drilling bucket: the main function of drilling bucket is cutting and drilling, but it also has the function of guiding and preventing deviation. The pilot base drilling bucket with positioning function, at the same time the pilot pointed tip can be changed into order, and the number of teeth of the drill view is not common, the drill body on both sides of the knife or door bar height is not common, these details can make drilling bucket drilling about uniform stress and prevent error.
Q:Rotary drilling rig deep hole Doumen difficulties what happened?
It can not be completed by simple drilling technology (rotary drilling rig does not need gas, water circulation is not needed, and soil is imported by spiral sheet, which we call simple drilling process)
Q:What is a rotary cast in place pile?
Rotary drilling rig is the first barrel type rotary drill through the bottom valve with broken rock and soil, and directly in the drilling bucket, and then by the rig hoisting device and drill rod of the drilling bucket dumping hole is proposed, so the cycle, constantly borrow dump, until the drill to the design depth.
Q:What brand of rotary drilling rig is efficient?
Has the product mix 12 tons - 28 tons of rice rice full range of Futian leiwo rotary drilling rig, with large 85m 2.5m large drilling depth, pile diameter, the parallelogram shaped international popular amplitude structure, flexible action, amplitude range, high construction efficiency.
Q:Construction scheme of rotary pile driver
Process selectionIn the construction of the project, the drilling method of rotary drilling rig and dry hole formation are adopted. Combined with the geological condition of bored pile in this project, many factors, such as large quantity and tight time limit, the backfill bit adopts rotary bucket drill, and the rotary digging sand drill bit is used in the cleaning hole. When rock is embedded, the bucket is drilled by rotary cutting, and the partially drilled sandstone is drilled by rotary auger bit. For some of the more abundant underground water piles, the slurry wall should be used as support, and the larger pile will be supported by steel support.
Q:Wylong machinery rotary drilling rig in the use of the external power? How many volts does it take to drive?
Rotary mining generally can not be connected to the electric burn diesel
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 kinds of rock entry models are there in the 31 rotary drilling rigs? Request introduction!
The rock type, strictly speaking, SR250 above can be into the rock, but the real into the current mainstream rock drill rig or 31 SR280R and SR360 three generation, the future of C8 series rotary drilling rig SR285RC8, SR315RC8, SR385RC8 as the main push models will gradually replace SR280R and SR360.
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:Long spiral applies to high-speed rail construction, civil construction, rotary excavation in relatively large diameter foundation construction, such as bridge foundation construction is more common.
The basic construction and working principle of rotary drilling rigThe mechanical device of rotary drilling rig mainly includes luffing mechanism, mast, main and auxiliary winch, power head, follow-up frame, pressurizing device, drill pipe, drilling tool, etc.. The parallelogram luffing mechanism, self lifting folding mast; automatic detection control of engine power, rotary positioning and safety protection: automatic detection and adjustment of verticality of drill pipe: the new technology of drilling depth preset and monitoring. Color screen display working state parameters, the control adopts pilot control, load sensing, maximize the convenience of operation, sensitivity and safety and comfort, the full realization of human, machine, liquid, electrical integration.
