……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 often does the rotary drilling rig do maintenance?
In drilling rig construction, it is necessary to do the routine maintenance work for the drilling rig at any time:1, each work before the drill rod feeder (wire rope connector), add butter;Note: make sure that the grease nozzle at the other end is unscrewed when greasing the end of the boot. This will help to squeeze the butter out. On the contrary, the oil seal in the lifting device may be squeezed out, and the dirty water containing fine sand can be easily entered, and the bearings can be worn down and the sensitivity of the lifting device can be lowered.Note: the new lifting device has been improved. Please contact the SANY customer service department for maintenance.2, each job before the drill rod to follow the guide frame (drill pipe support), bearing, add butter;3 、 always check whether the wire rope is in good condition;4 、 check the damage of tubing and sealing ring regularly, prepare spare parts to meet the urgent need;5, always pay attention to whether the circuit relay aging, early preparation of spare parts;6, check the drill rod lift (wire rope connector) bearing rotation is flexible, if damaged, should be replaced immediately;7. Check the bolts and pins regularly for wear and tear. If damaged, replace them immediately.
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:Why should auger drilling be done by means of jump excavation?
It is too tight, easy to punch through two holes, and after the hole into the cage, and filling, next to hit, you can not fill.. Hope to adopt
Q:What are the reasons for partial drilling of rotary drilling machine?
Geology: partial hole geology is the main reason, if the geological are loess layer, clay layer, so the hole will not appear error phenomenon, mostly by the geological changes, weathered rock, rock distribution and the drilling bucket uneven stress and the formation of.
Q:Rotary drilling rig new steel rope appeared a strand of steel wire, what is the reason for the stock?
A variety of commonly used wire rope phosphating coating steel wire rope, galvanized steel wire, stainless steel wire rope or coated steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment preferred anti galvanized - phosphorus corrosion prominent double coated steel wire rope.
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:Attention problems of rotary drilling rig
The rotary support first run 100 hours refer to, should check the bolt preload, after check every 500 hours of operation time, must keep enough preload force. Attention shall be paid to the operation of the slewing bearing in use. If the noise, shock and power suddenly increase, the utility model shall be stopped for inspection immediately, troubleshooting, and dismantling if necessary.The use of water is not allowed to directly wash the slewing bearing to prevent water from entering the raceway. Prevent hard foreign objects from approaching or entering the meshing area of teeth. To regularly check the integrity of the situation, if found sealed damaged should be replaced in good time. If it is found to fall off, it should be reset in time.
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:How is the construction of rotary drilling and piling machine built on the floor?
Use the mud pump to bring out the earth which is drilled, form a pile hole, then lower the steel cage and pour the concrete.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Mud: the mud of rotary drilling rig is made of mud while drilling, and more and more waste slurry is produced. The slurry of rotary drilling rig is made in advance, drilled and drilled again2: Mobile: rotary drilling machine, some mobile devices, and some walking style. Rotary drilling rig is tracked mobile
