……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:In the middle of the 220 rotary drilling rig, sometimes the drill pipe slipped down 5~6 meters at work, as if the rope was broken. What's the matter?
If the wire rope drops suddenly, it is the power head faultThe drill pipe suddenly slipped, like the first floor, and the inside of the drill pipe was badly worn
Q:Is the rotary drilling rig driven by electricity?
Of course, this is just a simple statement. It's very complicated. So. The driving force of rotary drilling rig is the internal combustion engine of diesel oil. The internal combustion engine then drives the hydraulic main pump.
Q:Does the rotary drilling rig need mud?
Rotary drilling rig needs mud wall protection. Except in the middle weathered rock formations
Q:200 rig footage every day how many meters
Footage number and geological conditions, drilling performance, operator proficiency, construction site conditions have a relationship, and to say that footage of the day, and the length of pile pile diameter has a diameter of 1.2 meters, with 60 meters long, 2 meters under the casing 0.5 hours, casing well Party A, the Commissioner General to look at. General situation, the first 20 meters of drilling, probably within 1 hours, 20-40 meters, less than 1.5 hours, 40-60 meters, less than 2 hours.
Q:31 rotary drilling rig, 280 pairs of steel wire rope, how long?
The main varieties of steel wire rope with manganese phosphating coating of steel wire rope, galvanized steel wire, stainless steel wire rope and coated steel wire rope, atmospheric environment, manganese phosphating coating can improve the wear resistance and corrosion resistance on the surface of the wire, inhibit the occurrence of fretting fatigue, and large increase in the fatigue life of wire rope, for reference only
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
English is rotary drilling rotary drill rig, in addition to the configuration of various rotary bucket operation, installation of casing drilling, with rolling tube device and grab for will casing construction; with telescopic guide rod grab underground continuous wall construction, with DTH of hard rock crushing construction; operation device can also be replaced for jet construction and circulation of construction; construction of pile foundation can also configure other forms of hydraulic hammer, diesel hammer etc..
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:Rotary drilling rig when piling, the drill bit off the hole in the pile, how to fish ah?
The depths of the parts are steel material, jack with a solenoid (suction of 500 kg is enough), tied to a rope and power line down, should be able to smooth lifting. Let go of their depth should be clear, can also be judged according to the change of weight is sucked, if you can see or hear it is more convenient.
Q:The best domestic rotary drilling rig, steel wire rope manufacturer
Therefore, it is necessary to have good flexibility, good abrasion resistance, good rotation resistance and good resistance to extrusion. Especially for the front of multi layer winding
Q:What is the lifting force of the main hoist of a rotary drilling rig?
The rotary drilling rig has two winches, one main hoist and one auxiliary winding, wherein the auxiliary winding is of some auxiliary function, such as hanging a protecting cylinder or something, and the main hoist is used for lifting the drill pipe.
