……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: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?
Screw drill to see torque, I use 10T-m. You might be talking about a small spiral drill. In the early 90s, I personally did 3.5 meters of pile, the use is: the first with a diameter of 2.8 meters of drill, and then use the diameter of 3.5 meters drill hole reaming, so completed the diameter of 3.5 meters of pile foundation.As for the rotary drilling machine, we can not rule out the possibility of digging deep, but the cost of equipment and on-site operations are cost-effective. Only the builder knows it; and when it comes to rock formations, rig it.
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:Various types of rotary digging drill rod head size
Because the rotary digging into the sea China earlier, there is no uniform B by national standard, but the host plant is basically the same, but the difference is mainly divided into two types of schools: as schools, using standard rotary drilling chassis, the stability is good; 31 schools, using the general excavator chassis, stability has been lacking, but saves cost
Q:How long is the auger type 360?
The drill rod of the rotary drilling machine is now extended from the lower part of the hoist, the steel wire extends out, and the hoisting rope is retracted. But some rotary drills can be extended either by a crane or by gravity.
Q:Does the rotary drilling rig require a national issued operating permit?
Special equipment safety supervision regulations of the second mentioned in this Regulation refers to the special equipment safety and risk of large boilers, pressure vessels (including gas cylinders, the same below), pressure piping, elevator, crane, passenger ropeway, large recreation facilities and field (plant) in special vehicles.
Q:How to choose the drill bit of a spiral drill?
Each drill bit, its role is different, and then the Xuzhou sea GREE machine manufacturing company to tell you in detail about it ~!First, core auger bitApply to gravelly soil, medium hardness rock and weathered rock formation.Second 、 core bitSuitable for weathered rock formations and cracked rocks.Third 、 single bottom layer soil drilling bucketIt is suitable for the construction of clay layer and dry hole.Fourth, double bottom rotary drilling bucketSuitable for the flow of sand, sand, cement poor size smaller pebble layer, wet drilling rotary drill bucket can also be conducive to the construction of the bottom of the hole hole cleaning using double bottom conditions.
Q:Wylong machinery rotary drilling rig in the use of the external power? How many volts does it take to drive?
Rotary mining generally can not be connected to the electric burn diesel
Q:The Montreal rotary drilling mud powder special effect is good
Use the Montreal mud powder we built in the West Zhengzhou North Sanhuan Henan province Forest Park interchange site every day a rig can pile 3 to 4, if the bentonite for most 2 really benefit.
Q:Construction scheme of rotary pile driver
Overview of drilling hole of rotary drilling machineAccording to the geological conditions of this project, and design requirements, combined with the pile foundation design parameters and requirements of the owner, the engineering pile drilling technology using rotary drilling rig, concrete using commercial concrete and steel reinforcement cage hoisting welding forming, lashing, catheter perfusion underwater concrete.
Q:Rexroth leveling sensor rotarydrilling rig
Intake air temperature sensorRole: provide air temperature information for correction of fuel injection and ignition timing. Effect: idle speed is low, easy to flameout.
