……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 about the collapse of rotary drilling machine?
Drill rig is mechanical equipment for drill holes on the surface, can be a large outdoor wells, oil and gas well drilling equipment, small equipment or single movable, called spiral drill. The drilling rig can take samples of underground mineral deposits, or for underground production facilities such as underground machines, instruments, pipes and wells. It is a mobile device mounted on the truck, trailer, track, or is fixed on land and offshore structures (such as drilling platform, generally referred to as the "offshore oil rig", although the design does not contain a drill).
Q:If you have a project, will you make money from the auger rig?
Great profits, dry spin is the most afraid of lack of living
Q:What is the drilling speed of rotary drilling machine?
I just want to know that a range is the speed at which a hole is drilledIf you want to say the condition, the pressure is 6 tons. The construction stratum is a common surface soil layerQuaternary unconsolidated layer, gravel layer and bedrock layerAbout two meters in diameter
Q:What is a rotary pile?
The rotary excavation pile is the pile type constructed by rotary drilling rig. It is called full blown bored pile.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Drill pipe: the drill pipe of the rotary rig is 3 meters per section, and the section of the rotary drilling rig is telescopic. It is in place
Q:How much does a rotary rig for Sany cost? A?
That depends on what type, model is not the same, with the chassis is not the same, the configuration is not the same, the price is not the same
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:Rotary drilling rig application
The main purpose of rotary drilling rig is to:Bored pile foundation engineering rotary drilling.
Q:How can the drilling rod of rotary drilling rig be telescopic?
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.
Q:When the rotary drilling rig is working, how does the rotated soil enter into the slag bucket?
(1) rotary drilling rig is the soil dust into the drilling bucket by drill pipe and the drill bit rotation and gravity, the soil dust filled with drilling bucket, lifting drill unearthed, so by drilling bucket rotation, soil cut, lifting and unearthed, repeatedly into the hole. According to drilling technology, it is divided into casing drilling method and stable liquid wall drilling method without casing.(3) the rotary drilling rig is mainly composed of operating system, power system, running system and drilling system (guiding column, drill pipe, drilling barrel, long and short spiral rod). Its operating system is mainly controlled by computer and hydraulic transmission. The power system is provided by diesel engine to drill and walk power, and adopts caterpillar type walking system (usually modified by excavator walking system).(4) drilling system is composed of drill bit and drill rod. Drill bit is made up of spiral drill and slag bucket. The drill bit is varied, and different drill bits can be changed according to different geological conditions. The chip type pumping rod drive a rotating drill bit drilling pressure and transfer required torque. The drilling rig is equipped with vertical and horizontal leveling system to ensure the verticality of the bore and to show the depth of the drill tube at any time and to keep abreast of the drilling conditions. The drilling rig has wide application range and high efficiency, and different drill bits can be configured according to different stratum during construction:
