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:Price of small rotary drilling rig
This is mainly due to customer driven rotary drilling rig drilling depth and pile diameter limit, the depth and diameter of the smaller the lower the price, on the contrary, the higher the price.
Q:What are the advantages and disadvantages of the construction of the bored pile with auger and rotary drilling? Another auger can drill 1800 diameter piles?
About partial holes, holes in the deeper, the probability of partial hole is bigger, so the rotary drilling rig is generally shallow excavation, not many partial holes, and the spiral drill can generally be deep drilling, there are partial hole phenomenon, especially in the condition of non-uniform strata.
Q:How to distinguish the performance of rotary drilling rig?
It adopts box type structure and has built-in clapboard to strengthen it. It has strong rigidity and good stability, and ensures the resistance to bending and bending. The whole mast is hinged with four sections and three sections, so that the overall size of the whole machine is minimum, so that it is easy to transport.
Q:How long is the auger type 360?
The thickness of each drill string is controlled sequentially. Extend from coarse to fine. Retract from thin to thick.
Q:Rotary drilling rig deep hole Doumen difficulties what happened?
Cobble formations, which carry out drilling and collapse, are very difficult formations
Q:What happened to the black smoke from the exhaust pipe of the rotary drilling rig?
Check whether the leak valve pressure cylinder deposit or combustion chamber or carbon 5, check valve check check the ignition advance or deviation ratio consult step related service station for inspection on automobile exhaust smoke introduced hope you help the original wish you a car.
Q:What bucket teeth are used in rotary drilling machines?
Rotary drilling machine selection bucket teeth must select special rotary drilling machine bucket teeth, after all, in the ground tens of meters, can not be like excavators, to spin wear-resistant
Q:220 rotary drilling rig can adapt to what kind of soil?
Rotary drilling rig is a kind of construction machine suitable for drilling operation in building foundation engineering. It is mainly suitable for construction of sandy soil, cohesive soil and silty soil
Q:How can the rotary drilling rig not be pulled out of the ground?
I have also encountered the main winding wire rope broken, but not so deep as 8 meters. Try to connect the main winding wire rope, then put the power head in the lowest position, connect the power head and the drill pipe with wire rope, start the main hoist on the machine and start the power head at the same time. In this way, the power head, the pressure cylinder and the main hoist are combined to raise the drilling rod. Good luck
Q:What are the equipments used for bored pile construction?
The drilling method of bored piles can be divided into impact drilling, rotary drilling and rotary drilling. The commonly used drilling rigs in construction are percussion drilling machine, rotary drilling rig and rotary drilling rig.
