……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 a rotary drilling rig
You are not open rotary drill, the dray and digging machine is the same.
Q:What's the minimum cost of a rotary drill? How much is it?
Rotary drilling rig rental prices last year at this time, about 220 is 14~16, in case of a month
Q:How many litres of oil are usually consumed per hour in a rotary drilling rig?
This is not sure, depends on what type, and when the work is not full power work.
Q:What brand is the best for rotary drilling machine?
Domestic rotary drilling rig brand, that is, Sany, sunward, XCMG, Zhonglian and so on. Among them, 31 of after-sales service is the best, but its host price is also the highest.
Q:Is there a need to calculate the construction and transport of the mud pit separately in the budget of the pile driving pile?
There is no need to calculate the construction and transportation of the mud pit separately in the budget of the pile driving pile.
Q:How can the drill pipe cracking of rotary drilling rig be welded?
Or very good welding, and see what the substrate material. The shaft fracture can be welded. Tianjin source welding can be consulted.
Q:What kind of hydraulic oil is used in XCMG XR220 rotary drilling rig?
Summer fever is normal, at about 50-60 degrees on the line, the use of hydraulic oil is no problem, check the system has no leakage, and if there is leakage, and then a good hydraulic oil will also be hot.
Q:Kim Taixuan drilling operations and other brands of rotary drilling operation do.
Each manufacturer of rotary drilling rig has its own advantages and disadvantages, the truth is basically interlinked, but need to find out the performance of the machine, but also need a specific practice, you can try,
Q:Which is faster, the reverse circulation rig or the rotary drill?
The place is different. There is no comparability.The engineering process is different and the drilling rig model is different!
Q:What are the equipments used for bored pile construction?
Impact drills are mainly suitable for drilling in eggs (DRIFTS), stone soil and rock formations. The main equipment can be divided into two categories: one for the drill itself with the whole set of equipment, drilling frame, shock and lifting equipment; simple percussive drill another by double drum hoist with clutch components, the drill frame by simple rods. According to the circulation mode of the mud, the impact drill can be divided into impact positive circulation drilling and impact reverse circulation drilling.
