……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:The principle diagram of operating system rotarydiggingmachine
The rig can also be equipped with long spiral drilling, casing, and drive device, pedestal drilling bucket and auxiliary device, underground continuous wall grab, precast pile hammer device, rotary drilling rig main parts from site and working device, rotary drilling rig in enter the working state, the control system through the luffing mechanism of mast angle adjustment the mast and leveling, is able to drill vertical drilling, the power head provides torque to the drill pipe and the drill bit to do rotary cutting;
Q:200 price of rotary drilling rig
According to the brand and the place of origin is not the same. The price is different. Pure imports are more expensive than imported drugs.Imports are more expensive to assemble than domestic ones.
Q:How often does the rotary drilling rig do maintenance?
1) each movement shall pay the grease according to the lubrication sign, and the main part of Carter shall be carried out according to Carter's lubrication requirements. For example: turning on the car, slewing bearings and other relatively large parts of the rotation, it must be in the entire rotary surface plus enough butter, each rotation of a certain angle to fill once;2) lubricate the main and auxiliary steel wire rope and butter each share;3) apply grease to the three sides of the mast rail;
Q:What is the essential difference between rotary drilling rig and rotary drilling rig?
Rotary drilling rig is a kind of construction machine suitable for drilling operation in building foundation engineering. Mainly suitable for sand, clay, silty soil layer construction, bored pile, continuous wall, foundation reinforcement has been widely used in various foundation foundation construction, the rated power of rotary drilling rig is 125 ~ 450kW, the power output torque of 120 ~ 400kN / m, the maximum diameter of Kong Zhi is 1.5 to 4m. The maximum hole depth is 60 ~ 90m, can meet the requirements of all kinds of large-scale infrastructure construction.
Q:What are the reasons for partial drilling of rotary drilling machine?
Drilling bucket: the main function of drilling bucket is cutting and drilling, but it also has the function of guiding and preventing deviation. The pilot base drilling bucket with positioning function, at the same time the pilot pointed tip can be changed into order, and the number of teeth of the drill view is not common, the drill body on both sides of the knife or door bar height is not common, these details can make drilling bucket drilling about uniform stress and prevent error.
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:Rotary drilling rig how telescopic, I mean, what power so that it extends out of step by level, it extends out in a certain order?
Friction compression drill rod (abbreviation: friction rod, friction drill rod)It is generally used for drilling in soft formation, which can be used for drilling mud, soil, sand and egg (drift). The friction drill rod is usually made up of 5 sections, each of which is 13 meters long and 1~4 times longer than each steel tube. Drilling depth of about 60 meters.
Q:The best domestic rotary drilling rig, steel wire rope manufacturer
At present, the domestic and foreign rotary drilling rigs are not equipped with moving pulleys, so the tension of the single rope of the steel wire rope is larger.
Q:What is the minimum diameter of a bored pile?
The minimum diameter of the bored pile is 310 mm;
Q:What kind of geology is a rotary drill suitable for?
Rotary drilling can be used in all geological conditions, but only in accordance with specific geological conditions, to take appropriate construction methods drilling tools
