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:Can the auger drill be drilled into the two - longest granite of the 1200kp?
Depends on the power of the machine
Q:Why is the rotary drilling rig put into the steel cage before pouring?
When pouring concrete to the reinforcement cage, if this time to improve the catheter, catheter at the bottom of the reinforcement cage distance is only about 1m distance, due to pouring concrete pipe after homing large impact force, promote the rebar cage floating;
Q:What kind of stratum is suitable for rotary digging pile?
Construction, according to different soil and geological conditions, according to the following provisions choose different drill bits:
Q:What are the hidden dangers during the construction stage of rotary drilling rig?
The rotary drilling cast-in-place pile is also divided into dry hole, soil sampling rotary pile and reverse and reverse rotation pile
Q:What is a rotary cast in place pile?
Engineering terminology, generally refers to the construction of rotary drilling machine pile type, the full name of rotary drilling pile, engineering referred to as rotary pile. Due to the use of mechanical work, the number of workers is not high, it can save a lot of labor costs.
Q:On the cleaning of rotary drilling rig
Rotary drilling, which meet the design requirements when the rotary drill is a few laps and idling; after several hours of the cage and the catheter after the hole and some sediment, have to clean the hole, now called the two hole cleaning. However, with the development of science and technology, the popularization and application of new technologies and materials. With the new wall protecting liquid, not only the wall is well protected, but also the hole and the sediment behind the cage seldom meet the requirements, the two cleaning procedures can be omitted, and the pile forming speed is greatly improved. For example, we use the Montreal chemical mud in construction after the Zhengzhou Xinzheng Airport, nearly 70 meters of sediment pile placed for 2 days no more than 20 cm. It brings great convenience to the construction.
Q:Are our common rotary drilling rigs the same as those for well drilling machines?
A dozen meters of drilling hole, is to drink water, drink water to break the stone, no stone rig also never mind, in Loess
Q:Which rotary drilling rig is durable and economical?
With FR622D FR620D, leiwo, comfortable operation, strong ability in rock.
Q:How can we not drill the rod and drill the rod?
Resolvent:1. Remove the drill pipe and remove the foreign objects.2, repair wear and deformation parts.3, open the drill rod, plastic alignment.4, adjust the operation method.
Q:The principle diagram of operating system rotarydiggingmachine
(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.(2) 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).
