……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 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. +1And you work with the stratum is related, as far as I know, the intelligent drilling machine is still more fuel-efficient, 31, Zhonglian is also good
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:Price of small rotary drilling rig
Tengzhou Kai Ao Construction Machinery Co., Ltd. small rotary drilling rig, piling depth between 1-40 meters, the pile mouth diameter range is 0.2-2.2 meters, the price is: 13.5-68 million between
Q:Construction steps of rotary drilling rig
The soil sand in the dump in earthmoving vehicles or on the ground to shut the valve back drill, rotary drilling rig rotary drilling rig rotary lock body, put down the drill, drilling, hole cleaning and determination of depth, into the steel reinforcement cage and concrete pouring, catheter, pull out tube and clean up the pile head sink silt backfill pile.
Q:Xr220a rotary drilling machine drilling 2 meters hole can reach 80 meters, its maximum drilling depth is 80 meters, the maximum aperture is 2 meters.
According to the technical parameters of XCMG XR220A, if the friction resistance type 6 section drill rod can drill 79 meters at maximum, the maximum aperture is 2 meters without bushing.
Q:The rotary drilling drill bit rock weathering by what
The rotary drilling drilling in weathered rock weathering, according to the hardness of the rock to determine what bit.Stainless steel drills are generally used. Especially hard cases with diamond or graphite steel drills.
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's the difference between a long auger and a rotary drill?
1., first of all, the cost of machinery, screw digging more expensive than the long spiral.2. construction methods are not the same.3. long spiral diameter generally below 1 meters, 400mm, 500mm, 600mm more, common drilling depth is generally within 15 meters, -32 meters. More than 1 meters in diameter, you have to use rotary digging or other.4. long spiral applies to high-speed rail foundation construction, civil construction, rotary excavation in relatively large diameter foundation construction, such as bridge foundation construction is more common.
Q:Which rotary drilling rig is durable and economical?
Futian leiwo rotary drilling rig is good, durable, cost-effective.
Q:What's the difference between rotary drilling rig and rotary drilling rig? What's the model?
Essential difference: 1, mud 2, move 3, drill pipe 4, drive 5, efficiency
